400 in, 2 out. 40x40 pumped 105 psi.

What pump do you use ,if you dont mind me asking?

It's the one RO Man supplies, Robert.

Here's a picture!

Cheers Nick

Does it give 105 psi on the gauge when producing , or is is 105 the max it gives ?

How much did it cost ?

I have a 50 quid pump from lidl that gives me 80 psi on the gauge while producing.

Sorry for all the questions !

No problem Robert!

Yes, it does produce 105 psi to the RO and I think it was priced at about £200.

I'll see if I can locate the invoice.

[Nick_Thompson]

Robert! It was £227 inc vat.

I must be doing something seriously wrong!!!
360 in and 37-39 out. Gulp

[Nick_Thompson]

What is your setup Mick.

[roundbuilder]

A merlin and have never had it below 37ppm running at 40 psi.

[Nick_Thompson]

I dont know much about those particular RO's Mick, only that the chaps here have mentioned that the high tds readings are a compromise for a greater volume of water production.

I have just moved and have nearly identical figures with a Merlin. A real downer after 240 tds and 70 psi. 200 litres in 90 minutes to 200 litres in 3 1/2 hours.  i will investigate what difference a pump will make.

Why the hurry?  Are you on a meter?

Two reasons. Convenience and I understand that the tds will come down quite a bit with a pump.

My TDS is now 2 after RO.  That's better.  My last RO filters only lasted about 10 months.  I flush them fairly regularly but I sometimes get slack with changing the pre-filters (so I've bought them in bulk now).

How long does your RO filters last?

I use two 150 gallon per day ones.  I don't see the point in upgrading to a merlin (or something like that) because mine produces at least 500 litres a day (which is what I use); so come a Monday morning I've got a full IBC; and I never run out of water during the rest of the week.

My tds after RO is now 34. Not good.
