Water spill feature draining after pump is off
- Thread starter EBD
- Start date
It will be this one. Currently fully open towards cleaning and close towards returns. Still at the time of test, all valves opposite of it, including the water feature return which is used to circulate water when the pool pump
Is on, were also individually closed just in case.

That’s what I thought. It looks like the only 2 valves it could be are the drain on the suction side for the second tier and the ifcs return. Unless there is another return on the second tier I’m not seeing from pics. It looks like the ifcs jet is missing a part, even with the ifcs valve shut off it could still return back into the pool floor cleaners. If you want to test theory turn ifcs off pull jet head and plug with a winter plug. Fixes are placing check valve on second tier IFCS return or you can replace head and see if that fixes it(not sure)

Going back to the check valves, I wonder if the check valves are the problem. Even though they look the same they might not be compatible with Hayward systems? I bought some these.
is there a chance the check valves are not fully compatible. These are the only parts that were changed and were not Hayward brand. I couldn’t find them so these Jandy check valves appeared to be the same size.

I don’t believe so, your Second tier is on the IFCS, so even if you closed off any valve it would drain back through the caretaker and back into the pools floor cleaner jets. I believe you need to test(posted above) if correct install check valve on return to WF after caretaker.

I don't think you can assume a Jandy check valve part will fit a Hayward valve. I know for sure Jandy and Pentaire are slightly different. (I have both.) Hard to believe that Hayward would magically match. I'll also ask this though I'm sure you have it covered: Were the new flappers installed in the right direction?
The return valves return to the water feature. Today I shut down the water feature pump and right after I heard a rush of water running down the main drain. This is how the valves were when this happened. The water feature pipe on the pool suction side was closed. The skimmer was partially opened. The main drain was completely opened. Water was rushing down main drain.
I then turned off the main drain valve off instead of having the off position on the water feature and the water flow down main drain stopped and the water feature bowl remained full. See picture.
Does this mean this pool was replumbed wrong. This started happening after the pool pump was replaced by a company.

Actually, i just got the correct part number and Hayward brand. Psxvde. Check valves are just generic ones.
Another thing I question is why do I have 3 water feature returns on the water feature pump and only one check valve. Wouldn’t the other two returns with no check valves allow water to go back up the returns, through pump and down the drain? All these three say water feature returns.

I don’t think it’s plumbed wrong just different, just use the water feature drain on FP to clean and leave it off on a regular basis. Just use the wf pump to run feature. You will have to isolate valves on wf to see what they go to, maybe pool features because they don’t have check valves?
So you are saying to close the main drain and use it only when cleaning at night? This could work but what a pain to do that everyday. I also noticed that air relief valve is having issues closing. Had to force it closed as it leaked. Going to change this next. I read on another thread that someone was having a similar issue and changing this helped.
I would confirm valves to make sure valve labels are correct by isolating valve to see what it does. If it is indeed the suction side, have that closed for the majority of the time, only opening to brush accumulated dirt and debris towards wf drain, maybe once a week. The wf pump will replenish/cycle the water. I have a feeling main drain and water feature are mislabeled on suction side.
You might be right. I am going to check on these. At least is somewhat isolated now but I am still baffled that pointing the valve closed at 3 o clock, which closes any water flow altogether to or from the “shared” pipe where the main drain and waterfall drain are (and flow towards the pool pump suction) , fixes the problem. If you take a look at the first picture, the waterfall drain is right next to the main drain and either could be closed by the jandy valve. In other words, I could close the waterfall drain, the main drain or the whole path altogether which will isolate the drains from suction side. Closing the path altogether is what is fixing it. If I understand this correctly, closing this whole path with the jandy valve at 3 o clock, shuts down the suction from the two drains which include main drain and wf drain and leaves only the skimmer as the source of suction. Since the pool pump is not even on and suction from feature still happens making it go through the main drain, doesn’t this mean there is still a vaccum created somewhere by the pool pump suction side perhaps by some air leak which is making water flow backwards?
Closing the valve at 3 o’clock would just stop the pump from sucking from those ports. The wf drain would still be able to drain back into main drain at the 3 o’clock.
Right, but why does it fixes the issue when closed at 3 o clock? What could be causing suction from waterfall drain into main drain when pool pump suction path is opened? Seems that closing all suction towards the pool pump fixes it.
The only thing I can think of is a check valve on the main drain, possibly underground. Verify labeling is correct and If mislabeled close off wf drain and see if it continues to happen.
Closed wf drain, wf went down. Closed Main drain, wf went down.
Closed both wf drain and main drain, feature water stays put
