Great! The handle on the MPV is right now set to BACKWASH. If you turned your pump on with this setting the water will flow out and be drained.Pictures the kids took for me of what is on top of the sand filter
Thank you. Should I turn that on know or wait until we know more.Great! The handle on the MPV is right now set to BACKWASH. If you turned your pump on with this setting the water will flow out and be drained.
The handle needs to be rotated 180 degrees to the FILTER position for normal water circulation. Read here about the functions of the MPV settings...

It seems that the cap is glued on. If it does come off it’s not easy, I can’t budge it.Can you stick your camera/phone above the sand filter and take a pic of the top of the valve? there is writing on multi-valve that will indicate what the positions are for. That will be a nightmare to service the way its stuck under the deck.
Also check the end of the "yellow" line marked "to where" . and see if the end caps are just stuck on without glue. At first I thought that line might be a backflush line and the fittings are stuck on so nothing crawls into the pipe when its not in use. But after seeing that its connected to the outflow of the spa pump I wonder if its a stub for something else.
My guess it was run for a stub for something else. After seeing your video its clearly part of the return line from the "Spa pump" after the ball valve. at first glance it looks like a drain line of some sort. Yes leave the cap connected.It seems that the cap is glued on. If it does come off it’s not easy, I can’t budge it.
Time to practice water testing on your pool water. Pull a sample and test forI received my tf-100 test kit and magnetic stirrer today.
That “waste” line that comes out of the back of the filter exits from under the deck towards the pool just like all the other pipes and is underground as well so that’s as far as I can follow it.Below are new plumbing diagrams. You have a very complex plumbing system and your videos were very helpful. I welcome anyone looking at this to audit what I marked up. I think I have the pipe flow figured out and this gives us a layout to discuss how Jess should startup her pool and operate it.
Here is the legend:
PS1 - Pool Suction 1
PS2 - Pool Suction 2
PS3 - Pool Suction 3
PR1 - Pool Return 1
PR2 - Pool Return 2 (which may be a return to the spa to circulate water over the spillover)
SR - Spa Return
SS - Spa Suction
Waste - Waste line from the MPV used to drain water when MPV set to BACKWASH, RINSE, or WASTE
The Hayward manual for the Variflo MPV on page 4 shows you what each of the MPV handle positions does.
- You have 3 suction lines into the pool pump. One is likely for the skimmers, one is for the main drain, which is which you will need to figure out once you get the pool running. From the fact that the ball valve on PS1 is open my guess is that is the skimmers.
- PS2 valve handle is broken off and we don;t know the position of the valve. It could be to the main drain.
- PS3 valve is CLOSED. It could be any number of things - a suction vacuum line; or another skimmer line; or even connected to the spa.
- I am stumped why there is a valve connecting PS2 to PR1. A suction line to a return. If anyone has ideas have at it.
- There are two returns coming out of the filter - PR1 and PR2. There is a knife valve that looks like it controls if PR2 is open. PR2 may run to the SPA and the knife valve controls the spa spillover running or not when the pool pump is running.
- A waste line comes out the back of the filter. You should follow it and figure out where it dumps the water.
- Then there is a separate spa pump, probably for spa jets with suction line SS and return line SR.
- As others have noted there are some flexible couplings that should be replaced by rigid PVC. Although I suspect they are there for a reason and it may not be easy to align all the hard pipe.
- Absorb what is here and then we can discuss the process for starting the pumps. The question is going to be if anything is leaking once the pump is running.
