Ive been doing my round for years now and following an op in hospital that will keep me away from ladders for a while im going to try wfp, got a system all set up but the ppm is up to 36 and wont go down the cleaner i brought it all from said he had replaced all the filters so any ideas? im sure its a 300gpd. any help would be appreciated same as if anyone wants to know what it feels like to be off sick while the suns out and have loads of work to do just ask me

[darren clarke]

u might need a di vessel in your van to finally polish it off

[Richard Neal]

im sure it has one the other side of the booster pump, the small pipe then comes out of that and goes into the storage tank

[Mike #1]

you have a di best thing to do is flush your  RO for 30mins without water going to storage tank then run normally for 10 mins then check tds the guy you bought of may not have run it for a few days so the tds will be up this should take your tds down to 000ppm

[Richard Neal]

how do i flush it? its got a red pipe with a tap fitting on it but i dont know what to do with it, sorry for being so green but my window cleaning technology has always stopped at the fairy liquid 

[geefree]

ONE HALF TURN OF THE TAP WILL FLUSH IT  oops sorry 

[geefree]

Whats your tds before it goes through filters ?

[Richard Neal]

cant remember exactly but up in the hundreds i did have the hose switched on and the booster pump going and left the red tap open for 45 mins but didnt make any difference

[Dave Willis]

He may have changed the filters (they are cheap) but the membranes could be shot (expensive) so if the ro is more than two years old I would say there is a good chance you'll need new membranes soon.

[Richard Neal]

how expensive is expensive?

[Dave Willis]

£75.00

[Richard Neal]

Thats about what i thought youd say!
so as i look at the filters would it be the one the other side of the booster pump?
can i tell by looking if it is worn out?

[steven ainger]

the membranes are on the top of the unit, and you cant tell if they are knackered by looking at them. test the product water coming out of each membrane individually to see what tds each one is producing, as it may only be one of them no good.

so ive got 3 verticle filters and i think its 3 horizontal ones on top of them is that them?

[steven ainger]

the 3 on the bottom are pre filters, change them about every 4-6 months, and the 3 horizontal ones on top are the membranes.

[Dave Willis]

Yep the vertical  ones are the cheap ones that protect the membranes usually changed every six months. membranes should last a couple of years and get the tds down to single figures.

[Richard Neal]

right thats me out of bed tomorrow! Thanks for your help i,ll let you know how i get on

thats good advice about the membrane wear and tear. thanks.

maybe a silly question......but have you got new resin in your DI?
