## Questions & Answers

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

**Q: I have water pressure of 100 will this damage the unit or just reduce its effectiveness**
A: The unit came with a valve to control the pressure going into the unit

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

**Q: one of the DI filters are leaking. Has anyone else had this problem?**
A: 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.
