Title: Merlin TDS
Post by: 8weekly on July 25, 2014, 05:25:31 pm: Would you say I need new membranes? My input TDS is 280 and output with a Clark pump is 24.

I used to get around 18 from 280 at my old house with a merlin no pump..

What's the pressure going in?

34 without the pump, but the meter is broken on the Merlin so not sure on the pressure. Membranes are 22 months.

Which pump Clarke 250e?

Some only run 3 bars which is about 44psi still to low
