Hi. I have two 2hp Whisperflo pumps that are on their way out and some ~20 year old PVC that probably needs some attention. The automatic controller simply turns them on for two minutes a day, and we turn them on through the iAqualink about 10x/year for an hour each. I need advice on two...

The intermatic junction box broke. I want to fix it. I was thinking the job would be straightforward (and it still is, I guess) but: 1) does this appear to be a junction box for the pool light? 2) what's the blue wire? It goes in the first conduit and the third conduit but it's unbroken. I...

Ok. This is actually about my fountain, which is plumbed just like a pool. It's 6*8ish, about 3' deep, 1.5" PVC, has a Whisperflo pump and a brominator etc etc. Pump is 30 feet away and 8 feet above the fountain. It has always had a small problem pulling or holding prime; sometimes (before I...

After two years of neglect, I have diagnosed and repaired my infloor system. Unfortunately it won't turn on due to inadequate pressure. The gauge shows 8psi and it needs 14-20 per the manual. I am getting ~28psi at the (clean) filter. The pool was installed (by the previous owner) by the...

Hi. I have a fountain and I am considering a new pump as the old pump is probably pretty inefficient and electricity rates are now in the high 20s per kWh. Considerations: 1. Existing pump is 1/2 HP. 2. Pump is ~6 feet above the water level in the fountain. 3. Presently have a small suction...

How "watertight" and "airtight" are properly installed PVC ball valves? I have what I think is a suction-side leak on my fountain circuit. Since we have owned the house, the pump would never self-prime (maybe that's to be expected as the pump sits 6-8 feet above the water level), but now it...

Hi. My wife noticed that the grass around our inground pool was starting to fall. We have owned the home and the pool for a little over a year. It "works" fine, and sits way, way above the water table. So I took out the shovel and did some digging and I have established that there are a number...
