Hi there,

Currently opening the pool and the backwash exit of my filter is leaking water when the pump is running on "high", or when I set it in position "Closed".

Yesterday I opened the filter to examine it and didn't find anything out of the ordinary. I tightened it better and it seemed to be better, but today it's leaking it again.

Another smaller issue is the pressure gauge is stuck on 12psi when the pump isn't running, or is on "low". It goes up to 19 on "High".

Attaching a picture in position closed and another in position filter with pump running on "High".

What could be wrong?

Thanks!

I would disassemble the multi port valve and inspect the spider gasket. Sounds like it is damaged or twisted. Fairly easy to do.

Get a new gauge while you are working on the multi port. TFTestkits has a really good one that's freeze protected.
 
I've disassembled the multi port valve (Hayward Var-flo XL) and didn't find any damage to the spider gasket. Please see the photos, it looked like the gasket was more like caulking than a removable part.

After re-assembling the leak was gone...

Well at least now I "know" how to disassemble a valve ;)

@duraleigh I saw in another thread that the Vari-FLo XL valve didn't have a gasket as such, which confirms what I thought earlier.

Do you see any issue in the pictures I've posted? Now the problem has disappeared when running on "High", but still interested in your opinion.

That is a gasket. For some reason that material deteriorates into a "caulking-like" material. Gaskets are available for that valve, or that assembly is available as well.
