Hey Lads,
I have a HF5 40/40 and at the moment my water pressure is awful. Only getting around 25psi. Any suggestions on a decent booster pump to increase my flow rate and save my membrane. Thanks, Phil.

they used to do these without the pressure switch at £50 less but can't see them anymore - been using these for 9 years

but no idea if that will be powerful enough

Thanks Spruce,
You seem to be the technical Guru on this site, so using your extensive and insightful  knowledge, which one of the 3 would you buy?
Thanks, Phil.

i use the exact same one as in the x line link (but got mine from gardiners) had it for about 18 months now and has been faultless.  I would check first though to make sure it comes with the fittings, pressure gauge etc that it doesn't show in their picture. You also have to do a small bit of wiring to connect the electronic cut off to the pump itself.

Hi, I to am looking for a booster pump and was looking at the Clarke CBM which is also in a link on this thread. I have a hf4 but a 40x20 would this pump work with this RO? I think it’s an equivalent to a hf4? Also do I need an inch hose or will it bust the pump or indeed the ro if I reduce it to 3/4 inch or half inch? I hope I haven’t  hijacked this thread but I am hoping to get one today and want to do it right first time.
Thank you in advance!

Darran has used his pump for many years so the pump side is a goer. But the pressure switch is the problem for me as it doesn't fit in with our systems.

The Machine Mart unit was at one time the one that GAPS water recommended.  The Wortex unit was the same one sold by Gardiners and I haven't heard any issues with them.

What I like is the flow switch (its not a pressure switch) and will switch the booster pump off when the IBC tank is full. This and the Machine Mart unit would be used in conjunction with a float switch and normally off solenoid valve.

I think P1W1 has added a couple of additional things to bear in mind when ordering either unit.

What would I go for? The Machine Mart unit is much more  expensive although you can get the same thing elsewhere a little cheaper.

The Wortex unit is a bit cheaper and again you might be able to find another cheaper supplier. There are cleaners on the forums who don't rate Xline's after sales service. I don't know as I've never purchased anything from them before.

Machine Mart has a good sales /service counter (where we live its excellent), but you pay for that service. Personally, I would with the Machine Mart unit, purely because its been around a long time and its what, another £65 more.

Gardiners used to sell the Wortex Booster pump for the PRF r/o (Merlin), the 4021 and the 4040.

Back in 2011 LeeGLS posted;
you need 2x 1"BSP to 3/4"BSP thread step down, and then you need 2x 3/4 male thread to 1/2 hose tail.

Thank you so much for your help! I’m going the Machine Mart route. 
Thanks again!

One other tip.

If you're setting up a new RO, I'd advise you to consider setting everything up from the start with 15mm John Guest fittings.  Half inch is a PITA, as you're stuck with expensive fittings from few suppliers.  Plan it around 15mm JG and if anything goes wrong, you can pop down to any plumbers' supplier and get replacement bits on the spot.

Some of these:

And some of these:

https://www.johnguest.com/speedfit/products/plumbing-fittings-home/brass-fittings/15-22-28mm-size-brass-fittings/

And you can set the lot up.

Screwfix are expensive (but handy when you need a spare) - cheapest I've found is JTM plumbing - cheap and next day delivery. So cheap you could buy a spare or two of every part and never need to go to Screwfix.

Sadly, ever since B&Q bought them out their prices have steady increased. They now seem to have the same ethos as B&Q has - its drifted away from Trade to Retail where there is more money to be made. As an outlet, they they seem to be very profitable whereas B&Q, with its high store maintenance costs are financially wobbling.


Sometimes there are some good tool specials, but the day to day stuff is just too expensive.

[Perfect Windows]

Indeed.

Toolstation is run by the guy who started Screwfix and seems better priced though their range is smaller.

£6.65 at Screwfix,  £4.09 at JTM.  My setup took five of them (three in the 4040 casing and two for the particle filter) so it really does add up.

Thanks for all the advice lads, I'll let you know how I get on!

Following on from Spruce's advice I've ordered the "Machine Mart" booster pump. Was thinking of putting it in the van before the pre filters. Is this correct and would I be able to use Hose Lock fittings or will they blow off with the added water pressure?
Thanks, Phil.

Just be aware that it's a big pump to be putting in a van in my opinion.
I connected the inlet hose to the pump using a jubilee clipped barbed fitting.

Thanks Andy,
Just took it out of the box and yes it's a monster!
