I just swapped out the flow restrictor on my RODI for a flush valve from BRS. It’s making a hissing sound. Is that normal? My last restrictor didn’t make a sound.

Thanks!My flush valve usually makes a little hissing noise when in use. Mine was leaking slightly, so just received a new one in the mail last night. Hopefully I have a chance tonight to install it... then I can see if it is also hissing
Yup! The connections look good. It sounds like it is coming from inside the valve itself. Just checked the ratios and I’m getting 3:1 (waste to product) so it seems to be working. Just loudly.Might I assume it has the John Guest / Quick Connect fittings.....just make sure the tubing is square cut and is pushed in all the way.
I’ll have to look that up. I’m not familiar.Are the ones from BRS Murlok valves? If not I’d recommend picking up those. Best thing I did to my spectrapure maxcap was replacing all the valves with Murlok fittings. * Edit I believe they are if you have the grey ones with green valve.
I was afraid of that.My flush valve on my BRS RODI hisses when open and flushing the membrane, but no sound when closed and the water is forced through the flow restrictor during normal operation.
I was going to say, mine hisses when closed. I also run around 85psi. No leaks or other issues, and production is great.Just talked to BRS. It's normal. Apparently if you run higher pressure it makes noise. I run at 85 PSI. Max for them is 90 PSI, I just found out. Good to know!
I'm running mine at 70psi. Will it produce the ro water faster if I turn it up to 85?I was going to say, mine hisses when closed. I also run around 85psi. No leaks or other issues, and production is great.
Yes - your membrane will produce water faster at higher pressures.I'm running mine at 70psi. Will it produce the ro water faster if I turn it up to 85?
ThanksYes - your membrane will produce water faster at higher pressures.
But be careful - your clear housings probably are not rated for 85 psi. If you are producing this pressure with a booster pump, make sure the pump is AFTER your prefilter housings.
You can plug in your water temperature and your water pressure into this calculator to see what your membrane will produce.
