Multi Port Valve Issue

[0xblurz]

Hi!

New to owning a pool. After opening the pool I was not getting good pressure out of 2/3 jets. It looked like the spider gasket needed to be replaced, and seemed easy enough. But now my pool is not operating correctly. The pump fills with water for a few seconds and I get good pressure out of the jets, but then it stops and water empties out of the pump. Also - when screwing the lid back on, it struggles to fully close without me applying pressure to the top. The handle is also popping up when fully closed.

Any help would be great. Sorry if I did not do a good job explaining.

It may not be anything to do with the valve. Check your skimmer weir. It may be stuck in the "up" position.
What lid "struggles to fully close?" The valve or the pump?
Changing the spider gasket should have no effect on the diverter assembly if it stayed in place when the assembly was installed.

The problem was the skimmer issue you pointed out.

For the valve handle, ever since changing the gasket, it has now become loose. I attached a photo. Also getting low pressure out of my jets.

The spring that holds the diverter tight to the gasket may have collapsed.
Which jets have low pressure? A spa?

Is that a big issue?? The handle still turns.

The pool return jets. One nearest the pump works well, the other two not so much

Is the diverter in backwards?

Did you take the top assembly apart and lubricate the O-rings?

Did you replace the non-metallic bearing?

Not usually an issue as long as the MPV is not leaking between its internal ports which usually shows up as water continuing to flow out the backwash line.
Since you have a new gasket, be sure to only turn the handle one direction or the other when moving between positions. Going to one position and then reversing to go back can cause the gasket to be pulled from its slot in the valve body. Its just good practice.
