RO/DI help

[discretekarma]

I finally got an RO/DI yesterday. It's the 6 stage unit made by The Filter Guys. I will be trying to install the unit in the laundry room some how and then going to some type of tub in the laundry room. I want to then set up an auto top off from the tub in the laundry room through the drop ceiling to my sump. My biggest problem that I've run in to so far is where to tap in to for the water. I don't have a sink in the laundry room. Can I split the cold supply line to the washing machine or with that cause problems with one or the other? I really don't want to tap in to a water line with the needle tap. It's not my house.

 

Also, what type of pump should I use to get it to the bottom floor? Mag? Power Head? Not necessarily the brand as much as what type and how strong.

 

Any help will be very appreciated since this is my first time dealing with an RO/DI and I want to make sure it's done properly.

 

Thanks

I was looking around in the laundry room in between games and found the connection. It comes off the house's main water somewhere and goes to the basement's kitchen sink. The blue and orange go to the sink and dishwasher. The hot splits off to the dishwasher but it looks like the cold goes straight to the sink. Can I split off this cold line to the RO/DI with some type of splitter from home depot?

Do your laundry room fittings yous garden hose threads? If so it looks like you are all set with what you've go pictured there? If not, I would just go ahead and tap into that cold water pipe with the needle valve. It looks like it would be a cinch to just cut the pipe and replace the connection before you leave (I'm assuming that "not my house" means you are renting).

With that being said, I think I understand where to mount it, how to run the supply line and the drain line as well. The I should have this done sometime this week. Next will be getting it from the RO/DI in the laundry room to the sump. I'm guessing I will go from the RO/DI to a tub in the laundry room where the auto shut off from the RO/DI will go. How should i pump it from that tub in to the drop down ceiling and then about 30 feet through the ceiling and down to the sump?

 

Should I use a mag drive pump? What size? Will a power head work? Thanks.

Sounds like you're going to need a pressure-rated pump. I don't think a mag will do it - though a 24 might. Add up the total head pressure and look at the flow distribution graphs - don't forget to take into account the elbows in the system which contribute to back pressure. You might want to look at something more along the lines of a Reeflo Tarpon:

Thanks. I decided to go with Dandy's Panworld 50px-x.
