New House, New Pool, What kind of filter is this?

HI all,

Brand new to TFP, heard about it from the finance who found it on next-door. I'm our new pool service going forward. Mega nerd here, so jumped on the fact that I now had an excuse to order a water chemistry set (got a TF Pro in the mail). Hoping to get the hang of this and really incorporate it to get the best results out of our pool without dumping $150/month at a pool service. We're closing on a house in a couple days and just did the final walkthrough today. I took a couple pics of the equipment and plumbing while I was there today. Would someone help me with what kind of filter this is? Maybe sand? Didn't get a chance to open it and didn't want to take a chance in case it wasn't something I was expecting. Any help on operation, like what the black handle on top of the plumbing does would be helpful. I'm assuming something to do with the likely obvious waste line with the blue tube connected to it?

Apologies for the completely novice question, but we all gotta start from somewhere right?

Thanks for any help and looking forward to preaching the good TFP word with time!

Welcome to TFP. You will find lots of help on this forum for any question you may have as you get to understand your pool and pool equipment.
Post a picture of your pool as well as that will help.

You have 2 inlets to the suction side of your pump. Probably a skimmer and a main drain but a picture of your pool would be helpful.

From the pump it goes to a push-pull slide valve. That is the item in front of the filter. In current position, the flow goes into the sand filter, then back out to the pool through that single pipe which leads to 1 or more returns in your pool.

If you twist to unlock and push the handle down (or pull up- hard to tell from the picture) the flow will backwash through the filter and go to waste down the blue hose.

You do not appear to have a timer on your pump so you must manually switch it on and off to filter the water.

This should get you started and you can come back with more questions.

Thanks for the quick reply, really appreciate it! I don't have a great pic of the pool itself, but will upload what I have below. I can take a much clearer pic on Wednesday. Note, the picture doesn't show it installed, but the pool does have one of those vacuum systems with the squid looking thing that runs along the bottom that hooks into the sidewall of the pool.

I certainly will be back with more questions! Let me know if the pool pic gets the gist across or if something more hi-res or specific is needed.

That is likely a suction side cleaner. There are far more efficient cleaning systems that do not require the running of the pool pump and clean the pool far better.

Thanks, that's good news as I haven't been impressed by the suction cleaner! Do you have some cleaning system suggestions that you've found work well?

This is good. Nice design. Suggest you make a hand drawing of your pool and mark where returns are located , the skimmer and drain. Also the connection for the suction side cleaner. Good reference if you have additional questions.

Thank you both for the replies. We should have the keys tomorrow and I can start my pool ownership journey. Good tip on the schematic. I need to create something anyway in my attempt to calculate the volume of the pool for some pool math, will document where the peices/ports are while I'm at it.

P.S. that cleaner looks freaking sweet - I need one now! Thanks for the video. Need to convince the fiancé that we need it too LOL.

Good news - I inspected the electrical on the pump and found a timer box on the far side of the house!! Set for 12a-6a daily. Is there a good way to tell the pump flow rate without measuring the output in the pipe?

I'm committed to getting the volume measurements figured out tomorrow after work so I can start working on the chemistry, will definitely hop in with how hot/muggy (for the desert) it's been this week!

I think I've talked the fiancé into getting the better cleaner after inspecting the one at the house today - the on there is pretty ripped up...will probably pick up an S200 from a shop on the way home from work tomorrow LOL! Got my TF-Pro kit in the mail today, secretly am a little excited about all of this.

To open the sand filter I'm assuming I need to crank on that top part of the filter with the black handles. Just giving it a little tug today, it is in there pretty good, I'm a little worried what I may find once I get it open if it's on there that tight, or is it under pressure even with the pump off and I need to bleed the system somehow before hand?

Few questions now that I've had some time to play with my new test kit. This is turning into a get me spooled up thread, so I appreciate all of the help so far. Just signed up for pool math premium to kick back to the TFP community/devs.

Question 1:
Pool services rock some HIGH chlorine levels apparently, who woulda thunk? Very much smells like chlorine, but at least I won't need to do anything with the FC levels for a little bit. As I was running some of the tests for the first time, I noticed the calcium test took a HUGE amount of drops to complete, that got me thinking....living in Phoenix with ridiculously hard water, is there even a point of monitoring the calcium levels since they will ALWAYS be high using city water?

Question 2:
Anyone know what this thing is in the wall of the pool near the steps? It really looks like a place to clip something.

Question 3:
Pool feels very hard, so I'm assuming it's plaster or some sort of concrete etc. I'm assuming it would be noticeable if it was a vinyl liner or fiberglass from reading the forums. Can someone tell from that pic of the thing in the wall?

Thanks!

Q#1
Pool services only come once a week cuz at that cost who wants them more. The chlorine smell is they load you up to last till the next visit but as you'll see it can't really work like that as for the ones that don't know better it is what it is.
Q#2
The wall thing I think is for tying a rope to separate shallow and the deep.
Q#3
It is a plaster pool.....

I'd leave the filter alone unless there's a good reason to go at it. Use your new kit and post all the levels including the CYA which may be off the charts.

You need to test your CH - about once a month - as our hard water and high evaporation rate will cause CH to climb. Then you need to enter all your test results in PoolMath and track CSI. Keep CSI in the range of 0.0 to -0.3 to keep scaling to a minimum. As CH rises you will need to maintain a slightly lower pH to keep CSI in range.

Once the CH gets above 900 - 1000, you will need to drain your pool (late fall thru early spring) and refill. Our tap water CH runs around 225-275, depending on water source and time of year. Some of us use a water softener plumbed to our autofill to help keep CH in check.

Fill out your signature with your pool, pool equipment (including manufacturer and model numbers) and you test kit info. This will assist us in helping you without having to ask about your pool and equipment each time.

Thanks for the tip - I'll keep that in mind.

Bummer - didn't know that was a yearly thing. How much are you draining? Just some to control CH during backwashes or a substantial amount?

Signature coming up tomorrow, forgot to grab the paperwork for the pool when I left today. Current stats are 21000g IG plaster (rough estimate using online calculator for oblong pool, will check with chemistry soon), single speed 1 HP pump (model # will grab when its light), Triton II sand filter with a push/pull valve, dolphin S200 vac on the way will have early next week), liquid chlorine, TP Pro test kit.

LOVED that rainstorm today, after it was done grabbed the pool chemistry for fun. As @wireform predicted, the CYA is off the charts (see pic). Something tells me I should take the tricolor floater the pool guy left in there when we bought the house out and lock the gates so the can't come back in! Here's the current stats of the pool in the loving care of the pool company (previous owner used pool company regularly):
FC = 7
CC = 0
pH = 8.2
TA = 160
CH = 500
CYA = 115 (I'm just guessing - there isn't a line about 100)
Temp ~ 90 (according to the old yellow ducky floating in the top 6 inches of water)
CSI = 1.08....yeah, a little high lol.

Where do I even start fixing the chemical "mess" the pool guys left me? Also, heads up I'm out of town for a week starting next Friday, so if there's a long term strategy it will need to wait till I get back, but would like to get the pool chemistry right before the vacation if possible...

Thoughts?

Thanks as always.
