I had to go for a quick refill I'm in a maisonette and block my neighbour in when producing "good job we get on well" the booster pump wasn't cheap though at around £200.

You can get a 160psi Shurflo pump which is also very good for boosting 4040 systems.

I have now set it up pre filters and running it at 70PSI with 7 on the TDS.....

Still learning....

Alex,


Are the pumps loud?

You mean after the pre filters?

[Highrise]

No, Before....


I am noticing that the TDS level is dropping as it fills up, Is this to do with the salt as the water is going through at a higher Pressure the salt levels are dropping quicker...?

TDS is now 15

They are as loud as the standard delivery pumps. So they do make a noise, but not deafening.

[chris@c.m.s]

Dave my pump is loud probably about the same as a hoover so I don't use it at night I refill when I get home and then relax with a few tins when the tanks full 

[mustafa]

 i run it 60psi    4 my ro      my tds 00  or 01

[Highrise]

Have been going now for about a week and now running at 60 psi starting of at 7 TDS and when the tank is nearly full the water going in near the end  is 15TDS.....

One thing I did forget to do was when I striped the system down from the van I stupidly forgot to backwash the RO unit which I did everyday in the van....
