They are spa jet pumps. They run for a few minutes a day to keep the pumps alive and keep the water circulating. And 10x a year when people actually use the hot tub that is integrated into our pool.

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...

When I say I killed the water, I mean that I stopped the autofill. Yes, I turned off the pump as well, so no water was circulating. Despite this, the fountain essentially drained until it was dry. I think that also means that the leak is below the level of the fountain's drain (or in the base...

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...

It's true that when I close all of the other valves and crank the pump to 3250(?)RPM I can get sufficient pressure for the Caretaker to run but I don't think that is the design condition (or the valves would be motorized like so many of the other valves). I mean, I am grateful for the...

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...

Thanks for the advice on the check valve. If mine is typical the job will be easier than I feared and you will have saved me a lot of trouble. I assume any pool supply store should have a suitable valve. I have four pumps: one is a circulator, two are jet pumps, one is a fountain pump. I am...

Hi. I bought a Superflo VS to replace my Whisperflo and in my haste I did not notice that the connections were different on the two models. "No problem," I thought. "I will just order a new union of the same make and mate half of the old union to half of the new union after gluing in the slip...

I think it would probably be best to get something adequately programmable so I could run it at a very low speed ~20 hours per day and run it hard for ~4 hours per day. I believe you, but I am surprised my existing pump is relatively efficient. It looks pretty old and it is noisier than the...

Oh, no. The fountain is separate from the pool but it is plumbed with Schedule 40, it shares the pump pad with the pool, has a brominator and an Aqua-rite (pool-style) filter. It currently has a 1/2 HP Whisperflo. I mean, it's designed to work with a pool pump. Not a $100 fountain pump or a...

It is a standalone fountain. mas985, you are the resident pump guru, right? The EnergyStar spreadsheet is blowing my mind. This is complicated!

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...

Thanks for the fast reply! The runoff-from-the-deck hypothesis makes sense. The pool has a valve that automatically fills it if/when the water level drops. Of course I could turn it off and watch it to be sure. But before d If the pool had a real leak, would I almost certainly know 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...
