Drip leak at eye of multi-port valve

[johnjmattingly]

Hi all,

I've got a small, drip leak coming from the "eye" of my multi-port valve (the clear plastic bulb that lets you see the color of the water when you backwash). It only happens under high pressure / high pump RPM. It's also annoying because due to the location of my pool equipment, I can't even backwash my filter - I always have to crack it and hose it down. So, it's a useless feature for me.

I'm wondering if a simple thread of silicon caulk would be the best way to take care of it?

It looks like the eye is threaded. Does it maybe screw in?

Any help appreciated, thanks!

John

It does screw in, silicon works fine. You could just tight'en it by hand. But if it's leaking while in filter mode you have an issue with your gasket.

The gasket for the eye piece itself?

The sight glass should not be under pressure.

The ball valve on the waste line was probably installed due to a leak on the multiport.

You can try to replace the spider gasket, but they can sometimes be glued in and it takes forever to remove.

You should also clean and lubricate the other O-rings.

Or, just replace the multiport.

I would replace the multiport.
