Question 1

how far can the purified water tube extend? im trying to run it a few feet like about 50 give or take.

Accepted Answer

It comes with 10 foot tubing. Fifty sounds like a lot, but I can't see why you can't do it other than making sure it is one piece to avoid leaks. I will ask in a reef forum for you to be sure, but I would say as long as you're not trying to run the ouput tubing upstairs it should be okUPDATE:  Nobody I asked has ever run more than 25 feet.  Those who do let it run a few minutes before collecting water to make sure it's all "fresh".  I think 50 is a lot, so maybe it's not quite that far?  Why do you have such a long run?  Mine is very short by design, but I could have put my RO/DI unit and my collection bucket in different places and would still not have more than 20 feet.  If you could provide details I am happy to help if I can.

Question 2

I have water pressure of 100 will this damage the unit or just reduce its effectiveness

Accepted Answer

The unit came with a valve to control the pressure going into the unit

Question 3

Flow restrictor is shown on the waste line but none was provided in the included parts.  Is it required?

Accepted Answer

You may want to double check your waste line, my unit came with it already installed on waste side. And yes, the flow restrictor is a must on ro systems as they create pressure throughout the membrane and maintain adequate reject and permeate flow.

Question 4

one of the DI filters are leaking. Has anyone else had this problem?

Accepted Answer

Similar problem first time removing filter canister.  Wiped threads clean and lubricated threds with a very small amount of silicone lubricant.  Canister hand tightened an additional full turn and did not leak.  Also insured sealing surfaces clean and not craked or deformed.
