Leaking internally?

[calvinwch]

I just noticed this year that when on filteration mode,I have leak on the waste output so I add a valve to close it.
Then while I was doing waste out I saw I have very slow flow on my return??? Do I have bad internal multiport? Affect my filteration?

Do I have bad internal multiport?

That's what it appears to be. Either the spider gasket inside or in some multiport valves the entire diverter part. They can go bad over time.

Bummer, I open top of the multi valve, it seems pretty good on the gasket and internal no sign of crack or anything. Could it be the plastic ring right under the handle? It broke as well?

Which MPV do you have? Do you see a make/model number or label so we can look it up?

So in your case, you would want to consider replacing:
- Key/Seal Assy
- Spring Washer Assy
- O-Ring Shaft Seal (2)
- Cover O-ring
- You may also need the spring washers.

That should do it, but feel free to look over the link below. You can also reach out to them on the phone or compare recommendations between them and InyoPools for a second opinion.

Be mindful of the costs for each part as they can add up. In some cases, it's just as easy and cost effective to order the entire Key Cover and Handle Assy all as one unit.

I guess best bet is just replace the whole key union, to remove the handle pin need compressed tool.
