I read a few threads and saw different answers, also different pool company gave different numbers too, so want to get some more info here. In Northern VA, so we do get freezing winters here. Company which closed for us indicated 1 inch below skimmer on their invoice (definitely feel they...

Single speed pump, the breaker on my main panel in the utility room is a regular 30A that feeds into the pool equipment subpanel (non-GFCI 20A dual pole breakers currently for the pump). I have a rather simple setup, currently just one single speed pool pump that was running from that subpanel...

We've only replastered it two seasons ago, and it was fine until opening today I noticed the crazing small cracks on the first step of the shallow end. That area would be always dry during the winter closed time and there wasn't any problem at least last spring. Is this something I should be...

Just noticed that my new DE filter has a much larger (probably one inch OD brass nut, since my largest socket 13/16 is still too small). It came with this large nut and large washer in front of the spring. On the manual it says part number 194997 which is a 5/16 nut. I have the small one from...

I have socks on both skimmers and wonder when adding the DE media, do I remove them first or not? Thanks a lot

Bought a supposedly new Jandy 2-way neverlube valve off ebay, and it came in with small amount of water inside and some crack lookalike stuff on the body. The seller was claiming those were cast marks and showed me at least three more valves with similar marks, and said the Jandy valves...

My local HD/lowes carry pipes, elbows and joints mostly. I checked the further reading and saw the mentioning of Buy Schedule 40 PVC Fittings at Discount Prices, also Ace hardware. I found the former's shipping pretty much kills the deal (starting from $18 for a few small/light parts) unless...

We are converting the ground level deck into a paver patio and during the process we decided to tear down this pool equipment shed and removed the gas line that were underneath the deck (pool heater was dead and we may consider that later with above ground gas line). So now we have about an...

We have this composite deck that is adjacent to the concrete pool deck. According to the location of two skimmers and pool equipment shed, the pool plumbing most likely is under the deck (not sure if it is above the dirt or not), also the gas line to the pool heater (not in use currently) is...

Recently got a new Pentair FNS plus 48 to swap out the old PACFAB NS48 DE filter that starts to leak. Currently has a slide valve and it looks like there would be some replumbing needed. I'm wondering if you guys feel MPV is better if replumbing is needed. I understand the added...

Cannot tell if it is a hayward or pentair, but it is an old typical push/pull backwash valve. A month ago I did a backwash myself for the first time, today noticed water puddling on the bottom of the plunge. Read a few threads and talked about having to replace the o-ring. Can anyone direct...

22k gal in ground pool, refurbed minimally back to operating condition last season. Earlier this season, the PACFAB developed some leak from the bottom, so I started to think potential replacement/upgrade. I saw quite a few fellow pool owners recommend changing that to cartridge filter for...

I have a few chlorine pucks that were in floaters for a week about two months ago, and put outside since. They are dry and exposed to sunlight. I plan to go vacation for five days and the plan is to bump up the FC before I go and put a few pucks in floater (with a friend coming to add 1 gal of...

I've seen folks recommend "rinse" cycle after the "backwash" with multiport valve, but I have a slide/push valve, so how should I proceed with multiple "cycles" of backwash (seen recommendation of backwash 30s, then back to filtering, then backwash again, for three times)? Or with my push/pull...

20000gal IG pool with solar blanket, no SWCG unfortunately. Currently CYA at 40,, and daily consumption with the cover on in high uv days (direct sunshine from 8am-5pm) is about 2-3ppm, less with cloudy days. FC consumption could be 4-5ppm with cover off during the PM sunshine and 2hours of...

It is actually right at the skimmer box area, tile is intact. Can I simply use this Henry 1 Pound Under Water Tile Repair | HD Supply, and do it with the current waterline (all underwater).? Is it simply just apply the henry material at the back of the tile and press it in? Should I do...

Just now, when my pump is already stopped, I noticed that my NS48 stainless steel DE filter was leaking water. I can hear the water dripping sound from inside. Checked all the visible and common leaking places, metal clamps, air pressure relief valve, the inlet pipping, backwash valve and pipe...

One side has oz the other side has ml looks like. I thought that would mean it's volume, but solids normally measured by weight i heard.

So we renovated this abandoned backyard pool (in my signature_) without much knowledge. It had a broken booster pump and broken Polaris 280 and all, so the pool company just replaced it with a new booster pump. With the pandemic price, the equipment of these cleaners are through the roof these...

We are in Northern VA, and a newly replastered pool since last summer. The first season was alright and we learned a lot about the TFP protocol and handled our water chemistry ourselves. Had pool company to close and open for the first time. New DE filter grid installed too. Pool was under...

Just got the sun2solar reel, have some question about the location of putting it. Our pool is this double roman end with two stairs on the side. What you are looking at is from deep end to shallow end. Shallow end has more space and closer to the garden hose (for cleaning), but deep end has...

We just cut the solar cover to fit the pool. Half of the stairs are exposed, also with gaps between the cover and pool wall due to the cutting. We do not have the reel yet, and have been just dragged up the cover when not using it and put it on the deck, and put back after swimming. I've seen...

I plan to use the vacuum plate Amazon.com : Hayward SP1106 Skim Vac In-Ground Pool Skimmer : Lawn And Garden Tool Replacement Parts : Patio, Lawn & Garden with my basket/sock on, so that debris would be in the basket instead of pump/filter side. I have a 3 way valve like the picture, two inlet...

Noticed water leaking through the upper side of the joint, not sure if that is the only place as the water seems to be running a bit more than it feels on that joint (upper side leak). I have never done any pvc plumbing job, more of a electronics guy, soldering and stuff. I guess the repair...

Pump is new single speed, there are two inlets (one for deep end skimmer+main drain; the other one from shallow end skimmer) going into the inlet pipe into the pump. The valve on inlet pipe going to pump only has three positions to either let one inlet from skimmers through or both inlets. My...

Moved from here.. Complete DE Grid assembly with Manifold @Andy49 @JamesW Sorry to bump this thread up, I have the exact same problem with the grid assembly. It bears the label of 192326, and according to the NS48 manual, it should comes with the manifold 192193, instead, it comes with...

Just noticed some discrepancy for adding MA to change PH value on the old calculation page: PoolMath For example, for 18k gal size, using the calculation of Ph adjustment, from 8 to 7.5, it says 25oz of 31.45% MA However, from the bottom "effects of adding chemical", add 25oz of 31.45% MA...

I tested my fc with k2006 at 645pm after no sunlight hitting on the pool, it was 3, I've been using 25k gal as pool volume (as I heard the water company guy said it probably would need 5 loads water to fill up, 5k gal/load). I used poolmath to calculate 102 oz of 12.5% LC to give a 4ppm raise...

First time plaster pool owner, just refurbed the old pool (I think more than 30 years old) three weeks ago, still learning everything from all you experts here. Current CYA is 40, CH 250, and I have been super cautious about these two levels as I do not want to drain and refill if not...

I used 10ml sample, and when added to 8 drops it turned blue but with maybe some red hue (or red stuff in suspension, not entirely sure, but it is light blue color and not changing back), added 9th seemed not change too much of the blue color. Do I count the 9th drop into the calculation...
