Frequently Asked Questions
Why only one tap?
Because that is all it can supply.
A domestic membrane makes litres per day.
Which as a flow rate is a trickle.
Far below what any tap delivers.
So it never tries to feed one directly.
Then how does the tap run properly?
From the tank, not the membrane.
The membrane fills it slowly.
Continuously, in the background.
And the tank answers the tap.
At its own stored pressure.
Which capacity actually matters?
The tank's, not the membrane's rating.
It decides how much comes at once.
Draw it down and the next glass waits.
Size the tank to the largest single draw.
Not to daily consumption.
Does it need its own tap?
Yes, and it is not optional.
Water leaves the tank at tank pressure.
Through a dedicated small-bore outlet.
So a hole is needed in worktop or sink.
Which on stone is a real job.
How is the reject water drained?
Usually a saddle clamp on the sink waste.
Fitted above the trap, deliberately.
So the reject cannot draw sewer gas.
Back through the connection.
Position it correctly, not conveniently.
How much cupboard space is needed?
More than people expect.
Pre-filters, membrane, tank and pipework.
Take a real part of a base unit.
And leave room for a waste trap.
Measure before buying.
Does accessibility matter?
It decides whether it gets maintained.
Filters have to be reachable to change.
A system packed into a back corner.
Gets left until something goes wrong.
Site it where somebody can kneel at it.
