[C-N-C]

Hiya guys .....
Gunna make this short...as im moving home
Im having trouble with merlin!!! water coming out has risen to 50 tds....it was always 27-30 odd.
Iv just changed membrains & postfilter,not long ago....things were working fine for a while,
But checked ppm couple days ago & it has creeped up to 50,i had a couple leaks in two membrain housing,but fixed now with plumb tape
still a lil bit of a drip from drain outlet on merlin........dont think that should be the problem?
I have used merlin with oil filled radiator close to it in when we had them cold days.....
I was thinking my water feed pipes run outside(lagged) underground,i just ,hope maybee a bit ice entred membrain? or the heater to close hasnt broke system.....
Any ideas will be much appreciated,
As you can understand i NEED to keep making water & this will use loads resin
I have a booster pump so my psi is 70
and my water is Very hard water  532ppm.......
and coming from merlin is 50 ppm...

Any help will save me money i hope

Thank you guys
take care

I had same problem, merlin was chucking out at 90.  Turned out the membrains were faulty, sent them back for new ones, and problem solved.

i dont like the sound of leaking membranes - surely this would affect tds 

have you tried replacing the seals.

and you have not mentioned changing the pre filter - did mine last week and made a small difference to tds but huge change in flow rate

also, just noticed your high TDS of your tap water.

520 is very high, and melins will reduce water by 90%, so a tds of 50 is about right for you level

Hiya guy's....thanks for ya posts fella's
I have changed pre-filter darran mate,
Was the membrain housing wot was leaking mate,prob needed new o ring seal,but used thread tape & it stopped dripping....so no leaks in membrain department,unles its inside merlin?or do you think o rings on membrain itsself could be leaking a bit?contaminating water??

Its normaly a lot lower than that Hermski mate....50ppm was the tds when i bought new membrains as i thought old ones were used up,i had them 3 years until it rose to 50ppm, i put new ones in it was 27-30 (ish)a couple of months ago....
I know 30 (ish) to 50 isnt much diffrence,but,i spend a fortune on resin man.....
Good work on working % ov ppm man
In the process of paying for a RO to be built of my local chemical factory for hard water areas.....nice ov them to help me out...just need to keep this merlin workin till new system ready....
Bin told of loads of folk now....merlin not for hard water areas :
Well thank you Hermski & Smudger,BIG UP YOU GUYS......

Take care & kind regards
