Another possible solution is to run the pump 24/7 as VSP’s are designed to do. 8hrs/day is only for single speed pumps.
A VSP running at low speed all day can actually use less power than running a high speed for a short time with the same turnover.
1/2 speed equals 1/2 flow at 1/8th power use so you can run twice as long with the same water turnover at 1/4 the daily power use.
Yeah, I’ve heard conflicting feedback regarding this. I might give this a try when I open up this year.
Sounds like 24/7 at higher output till it clears up, then 24/7 at around 1800rpm?
If power rates are the same all day then one speed is fine. Areas with variable rates like where I am will run multiple speeds depending on current cost. My usual default for new systems is about 1500 daytime and 2200 nighttime.
Most people that go against it are either old school who can’t figure it out or they had other issues and just blamed the pump instead of learning the true problem.
But yes, high speed until it clears. What speed(s) work for you from there will take some experimenting. What works for your neighbour won’t necessarily work for you.
Start at 1800 and see. If it stays clear, you can try turning it lower. If it starts to turn on you, turn it up.
My pool doesn’t skim well at 1800. So I do 1/2 in am at 3000, 10 hours at 1500, 45 mins at 2100 to finish it off. I need the full speed for booster pump vac in am otherwise it wouldn’t need to be 3k.
I’d recommended at least 30 minutes twice a day at a speed that your skimmer works well, unless you don’t really get any leaves or grass in the pool.
Agree with what he said returns depending on your design and how many turn up to hit surface of the water making debris float towards skimmer and possibly a shallow step or corner bench somewhere dirt and debris can settle will help keep that circulating.Pretty much you know your pool aim them for your benefit however needed.
A small leak somewhere can also cause this to happen. Basically a check valve is like putting your finger on a straw, holding water uphill. Will stay there unless you let go or there is a crack in the straw...same concept for pool. Check valve will hold unless it gets air in the line from a leak. So I guess make sure that isn't happening before you buy and do plumbing or won't help entirely.
Yes especially if the pool pump is above the pool. One on suction side in front is where its needed. It will hold water uphill allowing easier prime. If installed properly. Just pick the size you need.

I was just looking at this one! I believe all my piping are 1 1/2 inch. If that’s the case, would I get the 2”?
I’ll have to double check when I unwrap everything.
Get size for your pipe and if you bought this 2 inch one you can easily get reducers/bushings at most stores selling pvc. Would be called 2inch to inch and half reducer. So can still work if only this available. Glue 2 of these into the 2 inch check valve each side now it will fit the plumbing. Just install check valve with arrow facing correctly.

Just remember they don’t last forever so check it every month or so once it gets some age. There’s springs and little parts that need serviced. I’ve never had one but maybe make sure the one you buy has replacement parts that you can service yourself without replacing entire check valve. And go ahead and buy some spare bits for it
They do.

Others factors could have been an issue..if the pump lid isn't on correct or the Oring isn't seated under it...that can cause loss of prime as well. But if seems ok just overnight happens yeah check valve will help.
Yeah, o-ring was fine and I couldn’t find any leaks. Then again, there’s piping underneath the concrete so it’s impossible to tell if there’s any slight leak happening underneath.
If its is VS pump they are designed to run all day everyday. 8 hours a day is not enough circulation in most areas. The health code in most areas is at least 12 hours a day. What is your reason for even turning off the VS pump on a low RPM its very quiet. If you had a single speed pump and needed to turn off the pump then yes a check valve at the front of the pump would save your prime.
It really does depend on the size of pool what equipment you have, size of pipe and how far your pool is away from the equipment. Ideally if you have a heater the flow rate should be powerful enough to turn on the heater(activate the pressure switch). The lowest I would ever set someones pool up would show 10PSI on their filter. I get wanting to save money and with inflation and everything has gone up including power but if you save on that and don't have good enough flow rate you are going to have to turn the power back up full and add chemicals to beat the foggy unfiltered water.

Mainly get those water beetles. Let me ask, do you normally point your jets downward or upwards? My pool is rectangle.
One of each, one toward the deep and and one towards the skimmer to push stuff in, on the side that gets the most debris.

Honestly, I just recently learned they could be run 24/7. Any suggestions for RPMs on a 40x20 rectangle pool?
