Ppm in cornwall

Hi, a question to any wfp chaps in Cornwall, was wondering what the ppm is roughly? I know it's soft water area, but can't find out what the ppm is online?

Also what's the water pressure like there, generally?

Hi Monkeyman

 

Generally the TDS reading of water in Cornwall is within about 50-100ppm

 

Water pressure can vary greatly from area to area and from different parts of the same town as in most other counties. Here on the western edge of St Austell it is about 105psi from the tap.

Ok, thank you Alex, so you still have to put your tap water through a ro membrane then.

It is quite possible to use a DI only system here in Cornwall, but the most cost effective method  is still to use an RO system. Of course that does vary depending if you are in a 50ppm or a 100ppm area of Cornwall (St Austell is about 90ppm)

Thanks for the info, yes you may get away with just using DI in 50ppm area?

At 50ppm I would consider DI only especially as it can be more flexible. However at 90-100ppm I would always use RO.

Mine has gone up round here from 70/85 to 110/120 but I still use a double Di.

Am also on a water meter so the Ro waste bumps up my water bill.

Di is a lot more flexible and quicker.

I generally change one of my 16 litre Di vessels about every 5 weeks when it usually hits 05.

Where abouts are you in Cornwall?
