I can see your logic but it's missing some consideration or factors. In a particular situation your statement could be correct, but it's only certain conditions. If your pool is already at the desired temperature the heater would only need to be as large as the heat loss to maintain the temp...

Not to preach, but pool stores are not always accurate in there reading. I took the same sample to 3 stores the same day and got different reading from all of them and from testing myself. The time it takes to drive to the pool store you could have tested already. If you want to continue to...

I when RJ60 because my pool is 32K gallons and it was a free upgrade from the RJ45 at the time. The RJ60 is only $70 more than the RJ45. The CORE55 is also about the same cost as the RJ45. In theory the RJ60 should be the lowest cost over time since it can output more chlorine. If you are not...

Careful use of a heat gun or pouring hot water over the liner will help make it more pliable to align the screws. I have used an electric tea kettle to heat water and pour if over the line to help get the liner back in the track. Also wear gloves to help protect your hands and don't accidently...

Yeah that looks like an experiment that didn't work. I would suspect the light was on when it was not under water and it caused the potting compound to expand and break through the what was sealing it in place. I kill shut off the breaker to my light when the pool is closed or when the like is...

As Bperry state the light should float. Check to make sure there is no water in it. Would may need to replace the gasket and dry out the inside. Also check the ring in the pool wall to make sure the light can be installed in it. I am not sure how the mounting is on your model, but the metal...

Once it's open and you're brave enough to get in start checking for leaks. Make note of the level you found the pool at, it may have a leak at that level or could be lower. If the light is at this level there is a likely chance electrical connection to it is the culprit.

Typically it's almost the same cost to replace the entire unit and not just the tank. Last time I replacement mine the height was a little different as well and needed some of the plumbing changed as well.

Make sure the sealing surfaces are clean. Also check that the sealing face is flat. Are you sure it's leaking through the gasket and not where the cord enters? I have only used Pentair gaskets, if you are using a gasket from someone else maybe it does not fit correctly.

How long a patch lasts depends on many things. It could last the life of the liner or it could last days or anywhere in between. Depending on the location of the patch and how it was done, I would ask for a new liner or half the cost liner replacement. If the patch is in a stressed part of...

FYI the NFPA 70 - National Electrical Code is freely accessible. You do need to create an account, but it's free. With some searching the interweb and asking your favorite AI, you can usually find what sections on the NEC have the information you are looking for.

Consider how the irrigation controller is powered (power brick or wall wart). Not all fit under an in-use receptacle cover. You may need to put a receptacle and the controller in an weather proof enclosure.

If you have 3D printer or know someone who does you can make those plugs a lot cheaper. another idea to limit how far the ladder drops into the cup would be to put collars on the ladder to limit how far it can drop in. McMaster-Carr - not sure if this is the correct size I tighten the cup...

Compact the soil in the trench to start with if it's been disturbed. Then bed the pipe in pea gravel, stone or sand. Use materials that require little to no compaction around the pipe. Sand does have a greater risk of washing if there is a leak. Also consider the surrounding soils, don't...

For my outdoor holiday decorations I have poured concrete in the bases. I add enough so they generally stay in place other than when it get really windy. So far they have only blown over and once knocked over they don't go anywhere. Tried stone at first and it worked well, till they got...

You will have to check if your breaker is rated as a motor disconnect. Most likely it is.

I would guess, the leak is at the skimmer, based on where you are seeing soggy ground. Take a close look around skimmer and in it to see if you can spot any cracks. Might be able to patch them. On the plus side if it's a line or fitting break near the skimmer, there is a good chance it can...

If the skimmer is choked off and the pump can't enough water it will cavitate. The cavitation is what causes the raise in temperature.

I have added these to my skimmer baskets, GPIAngel Skimmer Basket Handle. Have lasted 11 years so far. I also have a basket without this for when I need to vacuum. There are cheaper ones on Amazon too not sure if they are same, better or worse.

My automation is my own cobbled together solution. I can do more cobbling to ensure the HP only runs when the pump is on.

Looking for recommendation for a 140K BTU HP (large single phase ). From looking over multiple manufactures spec sheet the efficiency are all similar (as expected). Are there mfg that are more DIY install accepting? Warranty for DIY install? Any brands more or less reliable than others or...

With that much water movement in the soil in that short period of time, settling is a concern. I would start looking for the leak at all the opening in the liner (steps, returns skimmers, lights, etc). How old is the liner?

No matter what paint you use it will be a maintenance challenge down the road. Prep to repaint is not going to be fun. Once it's painted it's almost impossible to undo. I would be more concerned with splinters over time. Wood generally gets slippery if mold/moss/mildew start to grown in it...

Depending on how the pool was built and backfilled it may be acting as a reservoir. What is the soil in your area, sand and well draining, clay and poor draining? is this from the water table raising? Are you in an area where the water table is close to the surface? If it's not the water...

Is it AC or DC coming out of the pump? I used a common power source (AC) and it works fine (i did not use the pump as the power source). If it is DC did you get the polarity correct (if it even matters)? I would think there should be enough amperage for it to work. Does the wifi board power...

The pump also needs it's configuration change so it knows if it is being controlled by the stand alone or relay control. If using relay control all DIP switch have to off except #1 has to be ON.

If you are going with relay control then it is not connected correctly, the green terminal block is used. Also the DIP switches are not correctly set either. The terminal block you used can be used to power you control board and to supply power to the green terminal block when the control...

Depends on which one you have or get. There is one takes 85 -250VAC the other takes 7-32V AC/DC or USB 5V. Also check to see what voltage is acceptable on the relay side of the switch if you are going to use it the same power there. I used this one...
