?     Asked on 5/8/2018by Johann

Is this sight glass plastic or glass? The plastic one I have on my MPV has oxidized and I can't tell if the water is flowing clear or not.

Hi, Johann. This Sight Glass is plastic.

why would a sight glass leak?

A  Answered on 8/27/2020 by InyoPools Product Specialist Lennox H.

Hi, John. It is cracked or has a bad gasket.


Est. Repair Time

Less than 1 hr

Tools Needed


Sight glass I had was also a vent and any backwash caused water to continue to spray out it as well

Removed old Sight Glass and gasket, then replaced with this, now works perfectly with no leaks.

Were these instructions helpful?
