i,ve just helped a guy convert to wfp, set up his ro but his water pressure to it is only 30psi,very slow.
it,s only a 100 gpd but think it should produce more than it is.
will a booster pump make much differance?? and how do they work?? and where is the best place to buy one?
thanks

HF5 40x40 membrane at that pressure will produce 10 times the amount of water he`s getting without a pump easily.

sorry hf5,whats this and where from please?

This is the kit he needs or the RO at least but he wants it in an HF5 version.

Same as my situation, though i started with a 75GPD RO

I have added a second membrane to push up to 150GPD. I have a 100psi shurflo pump which im going to hook up to my RO when i get chance. When adding a booster pump to the RO, make sure the pump goes just before the membrane. A mistake i made.

This is how the system should go

Tap - pre filters - pump - membrane - di filter

A 4040 would be better as production is quicker. Depends on the funds avalible though. If your interested in a 4040, then GAPS water is your place. They do special 4040's for those with low pressure.

Any other questions feel free to email me.

I had booster pump before the prefilters and never had a problem.

EDITED: I have a 4040 hence why I could do this, after pre filters for a domestic ro

Mine has been cracking the first casing on the pre filters.

I have spoken to John Hewitt who said the reason my casings were splitting was that because i was using the pump through the whole system. He runs his pumps between his pre filters and membrane on the systems he sells.

the booster pump on my ro is between the tap and the ro.
