O-ring lubrification and cartridge filter lid popping off

[tenkas]

I have a problem since installing a new VSP. It seems that at 2850 RPM, the lid pops off my cartridge filter since I cleaned it today (used to be ok). I suspect the o-ring not being lubed is the problem.

It is a Carvin cartridge filter and in the manual, it is written to use petroleum jelly on the o-ring.

This seems to be against all what is recommended on this forum, I even called the installer of the pool (this is a new pool) and they recommended petroleum jelly.

I guess worst that can happen is I need to buy a new o-ring?

Use silicone grease. Petroleum based grease will damage the rubber o- ring. I’m not aware of when silicone grease could harm your equipment.

Is it the filter in the picture. Unless the lock ring is not completely in the "locked" position, either the ring is damaged or the threads on the tank are. That's how a filter lid could pop off.

Hi,

Sorry for not replying earlier.

They changed my filter for a newer one, slightly bigger with a better locking mechanism (Carvin sherlock 160).

I have it lubed now, works great.
