Title: help with merlin
Post by: LBWCS on April 08, 2013, 04:49:40 pm

having some real problems getting tds down. I used to get 20-30 ppm from a 250 ish imput. now its gone upto 70-90!!
Membranes arent that old, and im getting 50 psi pressure. I know that isnt ideal but I used to get a lot better results.  Any ideas? It does kind of sound like there is a splutter of air aevery now and again which I dont know if it has any relavance.  Iv taken it all apart and all the rubber rings seem to be in place.  I have thought of a booster pump but now Im seriously thinking of just changing it. Any help guys???

Thanks

spluttering noise is normal I think " mine splutters" but as for the 90 read out no idea..
Is the waste water flow rate ok??

Yes I seems ok. Does changing the carbon block make much difference?

I'd change it on your normal 3 to 5 months interval.
270 to 22 at 44psi mine runs at
