View Full Version : RO/DI vibration/noise issue

03-15-2016, 07:49 AM
Installed a new shutoff valve on ro/di system. Worked fine for 6 weeks. Last week, there was a loud vibration/noise coming from downstairs. After a while, went down and the plumbing going into the RO/DI system is buzzing, vibrating, and . the RO/DI system vibrates and the whole thing vibrates a makes noise.

Any ideas? I have at a check valve on one side (not sure which one)

Do you have a flow restrictor on it, also anyway air could of got trapped in the membrane? You may want to let it free flow in a bucket for awhile to make sure there is not an airlock trapped in the unit.

I do have a flow restrictor. so just push the top off float up and let it flow for a while?

Sounds like too much pressure going in and either a bad shut off or failing one.
