Late start

I bought a metal frame pool on clearance last year and thanks to helpful input here, i realize i started too late, triple digit in full swing, and storing for next year, will start setting up in May. in May weather permitting.
I got a inflatable ring pool used knowing they don't last too long especially in the high desert. I am doing my best to level the ground, which is not easy in 105-111 temps. It is 12 feet and 3foot deep. Does leveling need to be perfect? Any margin of error?

Old Aluminum Coping Needs Repair

Hello all-

Been through a lot with this pool but this is the first time I've had to deal with the coping. It's definitely old and is something I've thought about replacing before, but this year two sections have pulled up away from the PT lumber frame that they were attached to, and I don't think I can get them back into place securely enough to really call it a fix. Problem is, I'm completely lost as to how I would go about replacing it. This style seems to be very old and most of my searches for aluminum coping show completely different styles, so not much to go on so far. In the pics you can see the coping and then there are a row of pavers next to it, surrounded by poured concrete that also needs to be replaced (lifted up in a lot of sections, trip hazard and rough on the feet). Not sure if there is a way I can remove the existing coping and put something else down, and then put pavers over top of that up to the edge? Open to any and all ideas, thanks!

Polaris 3900 sport replacement

My 3900 is about 3 years old.. bottom chassis is all scratched up and worn out to a point that there is a big hold and you can see everything inside. it is also leaking water where the water shoots up to the mesh.

Kind of sad to see its in this shape after only 3 years.

- Would you just get a rebuild kit and rebuild it?
- upgrade to a different model like quattro?
- other suggestions?

Pool Refinishing

We’re having our pool refinished with new tile, coping and gunite. They put in the coping and stone tile around the spa area and when I inspected it all a little closer I discovered chips the size of nickels and dimes in multiple coping tiles. The back side coping tiles have really bad jagged edges as though the blade was dull while cutting those tiles. In addition to broken pieces of the stone tile stuck in place. Plus the coping line inserting to the spa with a cut edge vs angled into the spa. There are a few tiles that don’t line up and are more than 1/8th of inch difference. I’m attaching pictures.

I just need to know if this is typical? I don’t want to be difficult and could understand one or two small chips but there’s over 10 tiles that have chips in them that they tried to fill with grout. See the pictures and please advise.

Bearing squeal, then it stopped

In-ground saltwater pool was rocking-and-rolling, clear as a bell, numbers looking good. Then we had a pool party with 40+ folks after which pool looked cloudy, flow light on the chlorinator went red, AND, the pump motor starting intermittent squealing in a way that was very reminiscent of when the bearings went bad in the pump motors on our hot tub. Fearing it would seize up, I ordered a new motor intending to put it in place. While waiting for the motor to arrive, I also opened up the DE cannister and did a super clean on the fins (yuk!), after which, flow light green, pressure < 15 psi, and pool back to crystal clear in < 24 hours . . . AND the pump motor is humming right along with not even a squeak.

Could 40+ bodies in various stages of cleanliness overload the system, i.e., the pump, and now that everything is rocking-and-rolling again, the pump motor is ok? Just trying to discern if I should replace the motor since I have one, or send it back (or try to resell it).

Age? We've lived here six years, and the pool has been here for a long time before that, so no idea how old the motor is.

Thanks!

1. Suction side air leak. 2. High CH, low pH, low TA, added baking soda but can't get rid of precipitate.

I was recently asked to look at a pool the forum helped me stabilize years ago.

1. The initial problem of why I was contacted was that there was a suction side air leak whenever the automatic pool vacuum (Barracuda MX-8) was connected to the skimmer. I changed the hoses and still got a leak. Then I tried hooking up 1 hose section at a time (this vacuum uses twist lock hoses). To my surprise, even with just 1 new hose 3 foot hose section fully primed with no air in it connected to the top skimmer, I would still get a large air leak in the pump basket. I would get no air leak when the top skimmer was just functioning as a normal top skimmer basket. Is the additional pressure caused by hooking up the vacuum hose causing the leak to appear?

It was time for a filter cleaning anyway, so I changed the grids and manifold (grids were well worn), changed the standpipe o-ring, changed the large filter o-ring, changed the pump basket o-ring, and tested every joint and plug by pouring running water over it with a hose. I couldn't find the air leak. Now I'm wondering if it's maybe a cracked skimmer pipe that only shows up when a vacuum hose is attached to it and there is additional load placed on the pump system?

I don't know if anyone has experienced anything similar, but any suggestions on where I might be able to trace this leak? I don't like running the pump too long in the air leak state as it will lose prime fairly quickly.

I've done a bucket test, and I don't seem to be losing any water. It just appears to be an air leak.

I resorted to just placing a basket in the top skimmer.

I was in the process of contacting a leak detection company.

2. I went to check the water balance.

The first test I got, the water was clear, but the numbers were way off.

FC 5
CC 0
pH 6.8? (It was below 7)
TA 10!
CH 1875!
CYA 30
Salt 3200
Temp 65
CSI -1.56!

When the forum helped me with this pool years ago, the CH was fairly high, but below 1000. Now it's solidly above 1000.

As far as I know, they were using liquid chlorine to chlorinate the pool. They floated pucks for 2 weeks prior to my arrival when they went on vacation.

From these results, I added about 10 pounds of baking soda with the goal of bringing total alkalinity to 50. For a 22K gallon pool I believe the calculation was for 16 total pounds of baking soda to reach TA 50. I'm glad I didn't do the full amount. I also added about 1/3 gallon of chlorine to try to bring FC to 6.

The second test 2 days later:
FC 7
CC 0
pH 7
TA 75
CH 1750!
CYA 30
Temp 67
CSI -0.18

The problem now is that I've got a cloudy pool. It's blue and I can see to the 3rd step in the shallow end but not the main drain in the deep end. It looks like baking soda hasn't dissolved or I'm getting calcium precipitating out. It appears that I overshot on the TA which makes me wonder if my pool volume calculation was off.

Any way to clear out this cloudiness?

I'm thinking this pool needs to be drained. I've struggled with this decision even years ago. I'm thinking of using an RO filter company. For a 20K gallon pool, they quoted me $1K for the job. I like the fact that most of the water will stay in the pool being that it is the hottest time of the year.

I'm not sure if this is better than just simply draining and refilling it?

3. Questions:

At this point, should I do the leak detection / repair first?

Is it even possible to do a leak detection in a partially clouded pool or should I try to wait and see if I can filter out all the precipitate?

Does anyone have experience with RO pool filtration versus draining/refilling the pool in the middle of July?

Thanks in advance!

Skimmer Issue

This is my first time on a forum so I hope I'm doing this right. If I don't get a response then I'll know I did it wrong. My question is concerning my skimmer. My algae problem is so bad this year that a "normal" vacuuming will not work. I'm having to vacuum to waste. This is the first time I've had to do this. My problem is that water is being sucked out around the vacuum hose where it's connected in the skimmer. The end of my vacuum hose that connects to the skimmer is larger than the skimmer hole so I have to use an adapter to get it to fit. It feels like a good connection but it obviously isn't. Therefore, the water in the skimmer is sucked out which causes a loud sucking sound. My question is will this hurt anything other than having to listen to the noise. I can still vacuum the algae but, of course, the suction isn't 100%. I just want to make sure I won't damage my pump or filter by continuing. Thanks for any input.

Replacement Aerator - Brass instead of Plastic? Increase gpm?

One of my 3/4 inch plastic aerators - Pentair 8620150 - broke and instead of getting the exact same cheap plastic version, I was wondering if I should get this brass version. Any thoughts on whether brass could cause issues with my salt water pool? It wouldn't be submerged and and most of the time no water would be in it since they drain out when not in use.


I also wanted to look at options that put more water through, for better cooling. The plastic ones only get like 12gpm for 4 with the filter pressure already at 15psi. I found this fire suppression option. Anybody have experience with that? However, I'm not sure if this will actually spray much at 10-15 psi pressure ... or if it will just gulp the water out without shooting into the air.

And I found this thing with a much bigger diameter hole in the center according to the picture but no specs / data on this.

Any recommendations?

Ran the pool pump without a filter assembly for a month and a half.

Our pool was opened as usual by our pool company. The water remained cloudy and the pool bottom was never cleaned despite multiple back washes and chemical checks. After a month and a half, we finally opened the DE filter tank and to our surprise found no filter in it. Just water inside the tank. We realized that we had no filtration for all this time and even the DE we added after the backwash ended up in the pool. The pool company had removed our filter and never replace it and didn't tell us about it. We had them come back for a service call to replace a cracked chlorinator, but even then they didn't say anything to us. I am concerned that running a pump almost continuously for 45 days could have caused damage to the pump and the impeller. Is it reasonable to assume that damage has occurred?

Dolphin Active 40 vs Active 60 - Pickup Mode?

Hey all!

So I have a 22k Gallon "bean" shaped pool with a 11" deep Baja shelf and a 17" deep seating ledge across on end of the pool. Its Grey Pebble finish if that matters.

Ive tested the Dolphin E20, and Dolphin Sigma so far.

The E20 did a good job cleaning bottom of floor, but would hardly climb the walls, wouldn't even make it up to Baja shelf, would just stop

The Sigma so far does an amazing job! It drives up and cleans the entire 11" Baja shelf and the seating area which to my surprise I was told these robots "dont do" However the Simga every single run has gotten stuck on my main drains (2) and the filters are a pain to clean.

Ive been in contact with Marina Pools & Margaret which have the best prices but aren't very good at replying. Im stuck between the Active 40 with Caddy $1299, and the Active 60 with Caddy $1599.

Pickup Mode is important to me because I have a bad back and dont like tugging on the cable, but Margaret & Marina claim the Active 40 does not have this, when every other website says it does?

Margaret did recommend the Active 60 as it would do a better job cleaning the shelfs with the Dual Drive, but also told me "not to expect them to clean the shelves much as none do".

My question to the community is which would be a better bargain for my case scenarcio? Does the dual drive and extra motor on the Active 60 make that much of a difference? the bottom looks like my sigma so im concerned it will also get stuck on my drains.

The Active 60 looks taller, will it be able to make it to clean my Baja shelf like the sigma? Or will I have better luck with the Active 40 cleaning my shelf/seating area with its lower profile?

The price difference is $300 which the only major thing I can say for sure sets them apart seems to be the warranty? Please help. Thanks!

Pentair FNS Plus DE Pressure Rise

Hi.
I have a Pentair 48 FNS plus DE filter and a Pentair Intelliflo pump. After backwashing and refilling my DE I notice the pressure start rising 16- 25 now and the GPM on the pump keeps slowly dropping over the last week.

I would assume I should backwash and refill with less DE. Maybe it's a combination of too much DE and excess dirt on the filters. Chlorine is fine at 5ppm and PH is steady at 7.6-7.8 for a salt water pool.

Just wanted to see if I was off base with next steps. Thanks!

Pool filter part - what is this?

I'm attaching a pic of the part I need to be replaced. It's a wire mesh that's torn. I'm three weeks into adding water to a newly plastered pool. I'm seeing some priming issues. My pool guy took a look and said this may have caused the blockage in the pipes but hasn't given me a final estimate or recommendationIMG_6455.jpg.

Any thoughts on what I should check or do next?

I've already cleaned those filters with acid and emptied out the plaster in that mess.

What is this inside the pool diverter valve?

First of all many thanks for all the useful insights in this forum and it has been a great help to me to manage the pool. We have an old pool that in the house we bought and learning how to manage. I am upgrading the pool pump to an energy efficient variable speed and also replacing some of the old diverter valves (broken handles, broken lube, ..). I noticed that inside the 3 port diverter valve there is some plastic hose between the main drain & skimmer -- sort of like prevent using either one exclusively for safety. Wanted to check what this exactly is meant for and if I should use same set-up in my new diverter valve. Please find the pictures where I have high-lighted the part in question. Thanks!

Pentaire problems/spa

Hello,
approx 8 years ago I had a custom spa/waterfall built (not enough room for a pool) . I left all decisions to the contractor who installed a Pentaire ic40 salt chlorine generator system. To date, I’ve had non stop issues with equipment going bad and spent $$$$ on replacing things. I have a company that maintains the spa weekly but I’m beginning to wonder if bad water chemistry has contributed to all the money I’ve spent replacing things - I'm on 2nd heater, second pump, 3rd set of lights, and now I’m told salt generator cell went bad. The cell was replaced yesterday but there are no lights. I’ve contacted the pool company that I’m seeing no lights. Could I have a bad salt cell AND bad power supply? As a point of reference, I noticed last week that the spa was cloudy. I went out and purchased a test kit and there was high ph and zero chlorine. What a mess. I really have no clue when the salt generator went bad but based on the maintenance log I found, there have been no entries for a year! I’ve always assumed this Pentaire system was too complicated for me to learn but now I think feigning ignorance is my biggest $$ mistake. Thoughts from the group?

Added DE to Sand filter for the first time...

First of all, I'm thankful to this community for all of the wealth of information provided here. Unrelated to the reason I'm posting now, but I'm on day 2 of my first SLAM because I got complacent about my chemistry and got myself a nasty algae bloom. This is our first full summer with a pool and kept telling myself "everybody said a saltwater pool was low maintenance, so what am I worried about? Look how crystal clear that water is!" I said that to myself off and on for a few weeks until our water turned green! I'M WIDE AWAKE NOW and this site has been a treasure trove of information over the last week or two. Water's more clear each day and my FC level right now is about 25 and my CC's have been 0 to 0.5 for a few days in a row. which brings me to the reason I'm posting.

I wanted to increase the filtering performance of my sand filter by adding DE so I followed the how-to on this site. My filter runs at around 20-21 PSI immediately after a good backwash and rinse, and it was at 21 psi when I went to add the DE to the skimmer. I added 1/4 cup in a bucket of water and checked after 2 minutes, and my PSI had already increased by 1 pound. I was expecting to have to add 1-2 cups, per the how to. Should I be concerned or relieved that it only took 1/4 cup?

Tons of rain and need suggestions please

It’s rained upon rain . I was constantly draining pool . It has been crazy weather . My numbers changed considerably. Here they are and I have a few questions please .
Fc 2.5 ( I added 35 oz 12.5 bleach ) already
Ta is 50
Cya 20 or Lower I added the whole bottle and still seen dot ( faintly )
Ph my dad says 7.2 I say 7.6
My questions are this
1. Is alkalinity up the same as baking soda ? The bucket says sodium hydrogen carbonate . Pool math says baking soda
2. To raise cya can/should I use left over chlorine tabs that have stabilizer ?
3 will the alkalinity up raise ph ? I want to use alkalinity up because I already paid for it and don’t want to waste money . I moving forward just do what pool math suggests .
4 . Wanna Gus’s my ph

My Heated Intex Prism 18x48 setup

i might have went a bit overboard for a Intex setup but hopefully it was worth it , I built my pool on a 24x20 pad made from 3/4” horse stall mats , I purchased the largest Intex pump and SWG they offer, a Hayward Pro Series 50,000 BTU Variable speed heat pump, Vinylworks sliding ladder with a custom 3D printed frame mount to secure it . We wired the heat pump with a plug as my garage is less then 8’ away , I want to be able to take it down easily. I still need to finish the landscaping and cleanup , but as of today everything is working, pump. Has no issue triggering the heat pump ACD72DAA-481C-43CE-8FDF-6F00343C8A59.jpeg

'Dishing' around return jet (pics added!)

I need advice! A month ago we noticed a symmetrical concave area around one of the return jets, about the size of a dinner plate, where it's sinking in slightly (1/2" or less). The concrete is not cracked but there is a white line around the perimeter where the dishing starts. Does anyone know what would cause it and how it would be fixed? I called our installer but he's not returned my call yet. This is their busiest time of year and they are very difficult to reach. I am losing sleep over it, worrying it's going to collapse during the night.

Tile Repair Question

I have just discovered a section of tiles that have come loose at our cover vault wall. The tiles are pushing up and need to be repaired.

Apparently our tile warranty was only 1 year, so we either need to pay the original pool builder to come do the repairs, hire any tile person we want, and/or DIY the fix.

Seem like a pretty easy fix. However, we would need to get the safety cover completely retracted and out of the way. The tile is above the waterline, so there is no problem with water while it is repaired and the mastic or adhesive cures.

One fix I thought of was to just shoot some good construction adhesive or caulk under the tiles and press them back down into place and be done??? Or I could buy some latex modified thinset and do the repair.

Anyone have any ideas or suggestions???

Thanks!
