RO filter rattling

[albinooscar]

I just installed a 5 stage RO filter last Saturday (22 March) and Tuesday (25 March) it started to make a rattling noise. It's not a continuous rattle. It only rattles in about 5 seconds’ intervals and then about a 1 second rattle. It does this until I drain (use) some of the water in the reserve tank. Once it recharges it starts the rattling again.

Could too much pressure cause this? I don't have a pump; it's just the city water pressure.

Could a faulty auto shut-off valve cause this?

Thanx!

Mine was doing the same thing. I just wrapped it in a towel to keep the noise down.

The rattling went away in a couple days.
