Puratek 100 RO/DI Help

HL649 · #1 12-31-2013, 03:26 AM

The unit is new out of the box. Well That is how I installed the RO membrane. So where is the flow restrictor? I didn't see any left over parts or instructions about installing the flow restrictor. I don't have any water at all in the DI canister.

What colour of hose did u use in the drain for the ro unit is it possible you can send me a picture of the set up or post it here. If I can't help u tonight I will defiantly try tomorrow and if that doesn't work we can try over the phone. Just got home from 14 hr day so I am starting to crash

So all your water seems to be coming out of the waste water line?

No water in waste line or production line Even when it goes through a flush routine.

So there is water going in building pressure but not coming out, seems strange almost like maybe one of the solenoids are stuck or hooked up wrong have seem this from new as well. Will it continue to run at 140 psi or does it cutout saying reservoir full.

140 psi, that's a bit on the high side and your RODI system is at risk of bursting a seam! This your normal house pressure? Most houses have a Pressure Reducing Valve somewhere to bring city pressure down to about 60-70 psi. In any case, if you have that much pressure & no output from either waste or product line, sounds to me like something's plugged up downstream of the membrane?

Not familiar with your brand of unit, but in many cases the flow restrictor is built into the outlet fitting on the membrane housing. On my system it's part of a manual flush valve plumbed in downstream of the RO membrane.

These units have a booster pump mine runs 130 ISh, also have auto back flush and a few other features, all in all about 3 or 4 solenoids on top of a normal unit.

I'll get a picture up of it later today. I kind of have a pretty busy day today.

I appreciate the help

Overview of the unit as installed

View of the waste line as installed

View of the output water line as installed

View of the source water line as installed

When I plug the unit in it goes through it's 15 second flush and then the source light and the producing water light turn on. The TDS meter reads 000PP but then there is no water at the sensor. They both will stay on indefinitely but no water gets through to the DI canister. If I get time I am going to pull th outlet lines of the RO canister and see if the water is making it through the membrane.
