Those of you who use this as a booster pump please help......

What connectors do you use at the inlet / outlet?

I am considering the choice of connecting standard household hose or John Guest 1/2" pipe (this is my preferred option).

Struggling to find the right connectors

Thanks for any help

I cant remember the thread size on the actual pump though, so check that.

This was a thread in September discussing this very issue

Thanks Guys

Having had time to think about it I am thinking of using......

then screwing this into the reducer.....

then inserting my 1/2" tubing

This would enable me to use 1/2" tube all through my system.

Only concern I have is would this reduce the pressure down into the HF4?

Should be alright on the delivery side providing the pipe from the  booster pump to the r/o isn't too long.

No its only about 1 metre long.

I am also not sure whether to position the pump before or after my 2 pre filters (sediment and carbon block)

The pump needs a good unrestricted supply, so better to have it before the prefilters.  Won't harm the prefilters, just puts extra stress on the unions/housing seals but ours has run like this for about 5 years without any problems
