I have been given a water filtration plant and would like to know what
it is so I can get bits and get it going.

It has two components. One being a blue gas type bottle that has one
top tap with a yellow pipe from it. The tap is a small brass butterfly
type and just shuts the bottle off. There is also a bicycle valve type
connection on the side of the bottle.

This is pressurised storage vessel. The bottom part is separated from
the top part by a rubber diaphragm. The Schrader valve (the bike valve)
is used to pressurise the lower compartment. It holds treated water.



The main part is a white panel about 10 inches by 16 inches.
This has three plastic cylinders on it, a white one on each side and a
bigger blue one in the middle. There is a black valve between the LH
white and middle blue cylinder.

Pipes go from one cylinder into another and I have blue, black, red,
and yellow pipes trailing around.

One must be a mains inlet and another the pipe to the outlet tap. The
yellow goes to the blue bottle. That leaves a pipe that appears to go
nowhere.

Any sort of help appreciated in this.


This is a reverse osmosis system. There are a few different
configurations, but the most common one with 3 cylinders has 2 activated
carbon cylinders and an RO membrane.

Water goes into the first carbon cylinder, then out and into the RO
membrane. Water comes out of the RO membrane and then into the second
activated carbon cylinder. The storage vessel is usually connected at
this point (where the RO membrane connects to the second activated
carbon cylinder).

The RO membrane also has a waste outlet, usually black, which needs to
discharge into your drain.

Without seeing it, this is about as much as I can tell you.
