R/O unit question

budhorse775 · 06/19/2010, 10:05 AM

I am planning on buying a r/o unit but am not sure the best way to store it. It will be attatched to my sink only when being used. Otherwise I would like to keep it "not visable" like my wife wants it. Will doing this create problems such as mold, bacteria, or shorten the membranes life?

Can you mount it under your sink? That way you can tie it into you cold supply and drain and always have it at the ready without the wife wining about it sitting in the sink.

Or how about mounting it in the laundry room near the washer dryer hookups? It has water and drain available and generally out of view of most people who would come in the house. Mines been there for 6 yrs and not in the wifes way or a place she minds it.

If i remember correctly, the ro membrane needs to stay wet. If it dries out completely, it renders it useless. As for the bacteria mold concerns, that is the purpose of the filter in the first place =). If there is some present in the filter, it will get filtered out and flushed with the outlet water on your next watermaking cycle. If you are concerned with build up, they make a reverse flush attachment that attaches easily that "strips" the ro filter of gunk before you use it.... takes like 1 minute to use and cleans the membrane

As pointed out above, once the membrane dries out, it's shot.

I'm a big fan of teeing off between the RO and DI to a tap or the icemaker. Best way to keep the membrane clean and happy is to use it often.

The big RO units in dialysis centers are typically set up to run a minimum of 20 minutes every four hours. The concept being to flush out any bacteria before they attach and multiply.

Good Luck!

Do most people keep them attatched to the water supply line and use a valve to stop the production? Also do they need to be mounted higher than the storage container?
