Ro Unit Extension

[demonmagus]

Hi, just wondering if it possible to extend the output pipe of a RO unit a long way, my tank will probably be in my bedroom, and the RO unit would have to be in the kitchen, the kitchen is actually the farthest room from my bedroom lol and it is a long way and up stairs to my bedroom.

Would it be possible just to have a huge pipe going into my bedroom from downstairs, or is there not enough pressure (as in not possible - I know it depends on my pressure). Although the wc's will be alright, I can't imagine lugging 25 gallons up the stairs for the first fill up



thanks

Well, there are a LOT of variables here, many of which I can't answer cause I dont know a thing about UK plumbing. Some basic questions though... Were you planning on running the tubing up through the wall or just kind of snaking it along the ground? What size diameter tubing were you planning on using and what length will it ultimately be (even if its a rough guess)

I know in the US where typical house water pressure is 50PSI, running say 50' of 1/4" hose will significacntly knock down your pressure and cause RO discharge to be painfully slow if not ineffectively slow. Now if you run another copper pipe at 1/2" or 3/4" diameter through the walls you can go a long distance before the pressure backs off too much.

How about running a hose pipe from the mains supply downstairs to the RO unit upstairs (bathroom, say, so you can easily get rid of the waste)?

I do that kinda thing, run a hosepipe from a tap outside through the kitchen window as I can't get a fitting to stay on the kitchen tap - the outside tap has a screw thread so it's a breeze.

that's a good idea actually, put does an RO unit go on the end of a hosepipe? are there any adaptors, I'll have to get a long hosepipe then, I'll see just how long in a mo

I have the same my tank is in a bedroom and the RO unit is in the garage about 40 feet away. I have used thin blue airline tubing to extend the outlet from the RO unit.. It is mains fed so there isn't really a limit to how far away it can discharge from the unit unless were talking really stupid lengths.

hmmmm, only problem is that with mine it will be coming from under the sink (is that mains? I dont think so), I could use it outside, but there may be a problem with freezing weather,


does anyone know if you can fit a RO unit to the end of a hosepipe?






thanks

Sure can, just a matter of getting the right fittings

 

[demonmagus]

oooh that's good news, do you have any idea of what fittings I could use?


wait a minute - just realised I have a sink in my bedroom hopefully RO compatible, do RO units make any noise?




thanks

 

[SkiFletch]

Heh, they only make noise if they leak

If you have a sink you can just use the self cutting tap that comes with the RO-Man kit and will cut a small hole in the mains water pipe in the cold inlet to the sink. All water going to a cold tap will be under mains pressure its only hot water supply pipes that are normally tank fed. Buy the ro kit and the auto shut off kit, it comes with a float valve and a shut off valve that turns the water off when the float is satisfied in the bucket you are filling. Can you not install it anywhere in the room with the sink as you will have the waste pipe there as well so wont need to run it over a large distance/outside?.
