I’m renovating my pool/yard & have modeled the equipment & plumbing pad in SketchUp CAD. Does the plumbing/valves in the image look about right in theory? I’m not sure on what sort of valves would be best or correct, I just hear a lot about only Jandy valves. Should all the plumbing on pad be...

I’m close to getting started on renovating my pool. I originally planned on a salt pool but all I’ve heard from folks in the Phoenix area is to avoid them due to deck issues and the hard water here. Pool is in ground 16 x 30, 25k gallons, gunnite, 3 return sets, 1 skimmer, aerator, whip cleaner...

I’ve been fighting some black algae and in one particular spot that appeared the worst after regular brushing with a stainless brush a different material/texture was exposed. My first guess is the plaster is gone in this spot & the gunnite shell is exposed? It’s a brown color & the small circles...

Is there any way to stop (at least temporarily) a small leak from an old gate valve without dismantling the valve/piping assembly? Recently I've noticed both of these gate valves leaking at the interface between valve and piping (as best I can see). I believe one controls return flow and the...

Hi, I’ve noticed water leaking slightly from my pools backwash pipe so I’m assuming the push/pull backwash valve is not sealing correctly? It’s a Pentair Triton sand filter & im assuming Pentair push/pull valve, guessing from the early 2000’s. The valve housing is beat up from previous owner...

Well some black algae has reared its head again. In addition to the stainless bristle brush I have I want to try directly scrubbing a chlorine puck on the affected areas. Is there a particular holder that’s recommended? Looking around online I’ve just seen plastic holders that appear pretty flimsy.

I’m going to add borates to pool but need to determine the quantity required for the suggested 30-50 level. I have the Pool Math app but didn’t see anything in it for that? Is there a calculator for this somewhere else? Thanks. (It’s a 24000 gallon in-ground pool).

Is there a preferred skimmer diverter plate flap position? I’ve been leaving mine fully open. If fully open will any water be pulled from the main drain? It seems like some sort of ratio between floor drain & skimmer would be preferred. Maybe leaving the flap 3/4 open? If you ran without one...

I recently tested the CH level in my pool & the fill water at source ( pool fed from exterior hose bib, city water). Note we had about 2” of rain over last few days. Results: Pool: 1350 Hose bib/fill: 375 I know the pool value is real high, but wonder if the two values should be relatively...

As title says is there a calculator available to determine how many chlorine pucks are needed to keep chlorine level of pool safe without adding too much CYA if you can’t maintain pool for a week? I’m going to be out of town for a week & don’t have any way to add liquid chlorine while gone. Thanks!

I discovered some small bits of black algae in my gunnite/plaster pool in areas where the paint has been removed (previous owner painted it, stupid). Question is I bought an 18” stainless brush & wonder do I scrub until the black algae exterior is removed/broken & floats away, then perform the...

Anyone have a recommendation on a submersible pump for use in pumping excess water from pool during heavy rains? I’m guessing something a 1/3 to 1/2 hp? Would probably need to pump water around 30’ to discharge area. Unfortunately my pool doesn’t have an overflow built in. Normally this isn’t an...

Wondered if anyone could help me figure out source of a sound coming from skimmer piping. At random times (maybe every 3 days) I’ll hear a deep, rapid “thud” sound coming from the piping above ground that goes from skimmer to pump. You can feel the piping vibrate as this is occurring. If you...

I had a few questions on the exposed plumbing portion of my ‘77 pool. I’d like to relocate the equipment a little further away from pool and trying to educate myself on the layout. The equipment is a simple pump & sand filter with a valve to turn on/off an aerator, one skimmer Anyone have...

I have the set of standard solutions from TFTestkits, they’re approx a year old. I filled the CYA testing tube up to the 50 mark as noted on the standard bottle but the water was perfectly clear. Shouldn’t the black spot on the bottom not been visible? Wondering if the solutions are too old? Thanks.

I was looking to replace the return jets in my 1977 pool with something you could adjust easier and that won’t crack. I went to remove and noticed that the first one fell out rather than unthread. someone had duct tape it around the portion that fits into the wall. it seems as if it is just a...

Previous owner of my house never kept up with keeping deck o drain free from dirt/debris etc. & it doesn’t function now. Is there a way I can disassemble the top cover to clean it out? Here’s a pic of part of it:

I have a rigid/in-ground backwash discharge piping attached directly to the valve on an older Pentair triton sand filter that previous owner installed (see pic). It’s convenient for backwash since there’s no hose to connect. Unfortunately the piping runs to yard in an area I need to re-grade &...

I’ve noticed that when people are playing in pool (mainly jumping around, resulting in a “wave” action in the water) occasionally I’ll hear a knocking/thudding sound that appears to emanate near the skimmer & portion of plumbing that is above ground, you can feel pipes vibrate slightly. I turn...

Just getting into the TF100 kit I recently ordered & was doing the calcium test today. The card said to fill to the 10 mark but I saw a video on YouTube where they fill to 25? Reason I ask is because after testing at 10, the red/pink color never seemed to definitively turn blue, just noticed a...

I recently purchased an M600 robot, it has worked real well as far as cleaning (the iOS app needs work). I’ve noticed that after (& during) the water develops a little haze/slightly cloudy; prior to running robot water is much more clear. Any ideas on why the cloudiness? It’s a 25k gal plaster...

Hi, did first time test of the chlorine levels w/ TF100 kit & curious about “turning clear”. As I added drops eventually solution went from pink to what I’d call a “cloudy” clear, no pink but not crystal/see through clear. After setting 30 sec or so the previously clear sample had a very slight...

I’m in the process of renovating my late 70s pool & was curious if anyone knew what sort of coating the previous owner applied. It looks like paint applied directly to pool shell that is falling off, but someone else thought it was coated with fiberglass & now chipping out. Below is pic of...

I need to replace my old single speed pool pump and filter, add SWG and automation (will also need to re-plaster soon as well). I live in Phoenix AZ and my experience so far with pool companies has been most of them are flaky. Do any of you that live in the Phoenix area have a recommendation for...

I’ve reached the point of replacing my pool pump & filter. The old one is a single speed with a sand filter. I’d like to have a Pentair variable speed pump and their cartridge filter. I’m just a little bit confused on which version of either I need there are several different types of Pentair...
