where is the best place to put the booster pump?    (outside tap then about 5 meters to shed then ro and di unit) should i put it on at the first point of entry to shed ?  on the tap inside the house  or inbetween ro and di unit (100gpd ro with di unit)

also its a ro man unit but cant get hold of them at mo    can someone breifly explain the 3 cartridges and top memnrne unit and how it works   it also said to flush unit but instructions bit tricky to understand
cheers

The best place to put the pump is just before the RO unit.  On the RO unit, the bottom three cannisters are, from right to left:

Sediment Filter
Carbon Block
Granular Activated Carbon

These three take out the nasties that would damage the RO membrane.  The top membrane unit then works on a reverse osmosis principle, only allowing clean water molecules through.  As the dirt builds up on this membrane it needs to be flushed off regularly.  To do this, open up the flush valve to allow most of the water freely passed the membrane surface and out the waste.  I would do this for about 3-5 minutes before each major tank fill.

i opened flush valve and the waste water increased in pressure and the product water stopped    is that right

sorry new to this am bit silly

[Alex Gardiner]

That is exactly what should be happening.

the instruction also mention a saddle valve    what is one of them



chheeeers

It comes as standard with a lot of RO-Man units.  It goes around a 15mm copper pipe and then you screw in a needle that pierces the copper pipe and when screwed out, provides you with a water feed.

cheers for all the help


must gt the pump fitted as the water pressure is low and is taken so far about and hour and i have just about enough water to fill a small glass and about 5 pints of waste   

you have been a great help

thank you
