My pool is 18x36 gunnite, with one skimmer, one sidewall and one main drain on suction side. I recently changed out my old Pentairt WhisperFlo single speed pump motor for the Neptune variable speed. Works well, pressure at returns is strong. As you can see in photos attached, swirling action in...

I am looking to replace an old single speed 1HP pump with a more energy efficient model. Service at the pad is 115V so want to stay with that. I know there are quality VS models that would be great but they are expensive. Does anyone still make a reliable two-speed in 115V that would be...

My Dolphin S200 starts normally, makes a lap across the pool, then stops and starts, stops and starts, raising up on its back wheels, for about 30 seconds, before continuing on its way. BUT then it only goes side to side in same line across width of pool at bottom of deep end, from wall to...

In this 18x36 gunnite pool, there are two returns (marked in yellow in photo below), and a single skimmer on far wall of deep end (marked in red). There are three suction ports: skimmer, sidewall and main drain, but I have only the skimmer line fully open. The pump is an older single speed and...

Would anyone care to share experiences with the non-adhesive vinyl pool floor decals available from a variety of online sellers? They come in different sizes and shapes but all seem to be 1/8" thick vinyl that you just drop into the pool and it sits flat on the bottom. Some example links...

Would appreciate any suggestions for weak suction and corresponding weak pressure in return lines but normal/stable PSI at filter and no apparent air in the system. Equipment pad is in garage, approximately 10 feet vertically below pool surface level and 30 feet away horizontally. Pool is...

I'm laying pipe in a trench to feed solar panels. As you can see from the pictures the angle on the 22° elbow is just slightly off so the pipe on the right does not seat fully in the elbow. If everything else is rigid already, is there a way to get this connection right so it will not leak?

I am installing a solar panel array (Heliocol) on a patio roof. As shown in the picture below, the feed and return lines come down from the roof along a vertical post, then continue into the ground where they run horizontally about 25' before turning straight upwards to the pool equipment pad...

This gunite pool has two returns (circled in red) and one skimmer on the far side. Pump is a one-speed and return strength is very strong. The eyeball on the back return near the steps is pointed down 45 degrees and straight ahead towards the far wall. The eyeball on the left sidewall return is...

Apologies if this has already been covered in prior posts. What is recommended way to wire new SWG control unit to same timer controlling the pump? See my setup below. Power from panel comes in from below (120V 40A), runs to pump plug-in box, which also feeds light switch box and GFI outlet...

Our gunnite pool was recently emptied and resurfaced (epoxy). I am slowly refilling it now by hose from house well water. Once I got to about halfway (12,000 gallons) I added one bottle of liquid chlorine and turned on the pump, using only main drain suction. The water had been crystal clear but...

I'm in Dutchess County, New York and we are installing an aluminum pool fence similar to one shown in the picture below. The fence is within 5 ft of the pool edge along three sides and further than 10 ft away on the remaining side. The electrician says he is required by code to bond each...

I am converting an old cement chlorine pool to SWG. There is no water bond device in old setup so we will add this at pool equipment pad while doing the SWG conversion. Can the new inline zinc anode double as water bond or only when using the "Pool Defender" product as shown below? If not, is...

Pool had finally become crystal clear after opening up to green water and going through SLAM process. For past week, water is clear to the bottom, all levels within TFP ranges. This morning I decided to throw in my Dolphin robot to help remove any debris from floor. It's been running fine for a...

Opened up in New York two days ago to green/algae. With mesh winter cover, CYA had gone to 0 so immediately added 4-lbs bag in sock (all since dissolved). Ph at 7.2. We skimmed the top for floating clumps of algae and then added SLAM level of liquid chlorine and have been running the pump and...

We live in New York City and have the pool pad with all equipment in the garage, which is 10 ft lower and 20 ft away from the pool. Our current setup uses an in-line shell-and-tube heat exchanger that is plumbed to our home boiler. It works ok but not enough to heat the pool in May or...

When lowering water level in pool for winter, the top stair or two become exposed and vinyl begins to come away from wall/step. Is that ok to leave for winter or better to not lower water that much? Water level is currently just below the returns, which are at 18", and a good six inches below...

I have this valve at the bottom of our combo skimmer/main drain (Hayward SP1082VG) : According to instructions, you switch between suction from main drain and skimmer by turning the red-handled valve straight up or horizontal (or in between). The manual shows a plate assembly for the opening...

I made the mistake of following package instructions on Home Depot CYA granules and sprinkled directly into pool. It's all collected at bottom of deep end and I'm worried about staining to our new (dark colored liner). I have the pump running continuously to help with distribution and dissolving...

I'm looking for a winter cover for new in-ground vinyl liner pool in New York (14x28) but as far as I can tell they come either all solid or all mesh. I understand there are real benefits to the hybrid models that are solid but with a mesh drain panel in center -- but only see that is expensive...

As seen in the pictures, our setup includes a 5-ft straight vertical run into the heat exchanger, with a flow switch and acquastat inline. Then flow switch and acquastat are wired together so that either can trip the boiler (e.g., if pump is off and there's no flow, zone should not call for...

Our PB completed the plumbing setup before the inline heat exchanger was available for installation. Now that we're installing, I'm not quite sure the plumbing is set up quite right. Would really appreciate any advise/observations on the setup and how it really should be arranged. As you can...

Per the image below there is a check valve and Jandy valve between the single suction line coming from pool and the pump. My understanding is that the check valve ensures that no water come through into the pump if the pump is not powered on and operating. Our equipment is in the garage a...

Pool and pump are less than a week old. Pump has run very very quiet on low speed (1400) without any issue but today, after pouring 2 lbs of stabilizer into the skimmer, the pump began making a buzzing sound you can hear in the linked file below. It may not be connected to pouring in the...

Mid-way through constuction of new inground vinyl liner pool that we managed to tuck into a corner of our backyard in the Bronx. 14x28 rectangular (which is maximum size allowed in NYC without prior permit) with liner-over-steel corner steps and deep end climb-out bench. Pictures of...
