i dont no havent got it working yet lol.

i dont think there is a diffrence just stronger etc for an extra 25.00 it was well worth it

[dave0123]

Thanks alan,

will give that ago 2morra! thought the stainless steel would be slightly less as its very strong but thin were if you had that thin on plastic it wouldnt be so strong if that makes sence?

yess pleased with the stainless streel  very strong arnt they haha! had bit of trouble getting the end caps in very tight fit had to be nocked in slightly couldnt imagine doing that with a plastic one? unless they connect diffrent.. Also got that clarke booster pump today and some fittings to reduce down to 1/2 standard hose so should be up and running tommorow.

thanks for your help! dave

[alanwilson]

no problemo davo.

the best way to seat the end caps is to get a little bit of pure water and wet the o-rings, should slide in easy (no jokes please)

[dave0123]

Tar Alan,


I didnt think of using water and didnt want to use anything else in case it interfered with the system.

[alanwilson]

yeah a little bit of pure water is fine, even a little bit of water ran through a carbon filter first (to remove chlorine) will do the same.

hope its all going well now

[tompoole]

hi
Dave, what Tds readings  before di do you get compared to your last ro

Cheers

Tom

[dave0123]

hope its all going well now

it is so far 



tompoole,

still havent got it running yet mate, should have running tonight sometime.

been busy yestaday so didnt have much time to do anything setting it up in garage.

[dave0123]

Iv just started running the system and i have a pressure gage before the filteres which is saying 15psi and after the filters the gage hasnt even moved? could there be a simple  explanation for this?

Hi Dave,

Bit off topic mate but have you notice a sharp increase in tds today. Checked mine this morning before stopped filling and it was 140ppm. Come back this evening and started filling and its at 255ppm plus the pressure has gone up by 10 psi?

dave

you have a pressure problem

[dave0123]

you have a pressure problem

think iv sorted that now! i didnt have the tap value slightly closed soon as i started to close it over both gauges shot up!  dont no if thats normal. still low pressure tho  havent got pump set up yet tho so that should sort it out.

your tds is normaly 140ppm? got u lucky git mines normaly about 380 - 400 todays its 340 lowest ever iv seen it. not sure about pressure mines allways bin crap from tap.

[colley614]

When I put my membrane back flush on the pressure drops by about 40psi. If thats what you mean? Plus when I first set up my waste pipe hadn't been inserted correctly so I was getting a back log of pressure. One day I leaned on it as the pressure gauge shot up.

Have you seen biscute lately? did he sell up or is he still knocking about?

[dave0123]

Carnt seem to get the TDS down below 39 

[alanwilson]

dave

you need to leave the valve open fully for 2 hrs or so on the first run to get all the preservative out of the membrane.

If your pressure is low (lower than 55psi) then get yourself a booster pump, the ones I gave you links to will be fine and you don't need one with a pressure regulator as that is what the valve is for - you can regulate the pressure yourself.

A pump will only set you back £80 - £100 and will increase production, reduce tds and preserve the life of your membrane and save you more resin.

From 350ppm with a pump you should be looking at a tds of about 007ppm.

[dave0123]

i have run the system with the tap open for a good 2 hours and ran with tap a little closhed for about hour n half.

i do have this pump just havent set it up yet

[alanwilson]

ok if you have everything I can talk it through with you now if you want.

[dave0123]

 thanks Alan,

 on setting the pump up?

i have one or two connectios to get in the morning! thats y i have just connected up without the pump today.


do you think with the pump running it will come down lower than 10ppm ??

[alanwilson]

depending on the chemical make up of your water it should do - what membrane did you get?  If you got the desal membrane I think it has a typical rejection of 98% so in theory yes 007ppm is reasonable.

[dave0123]

the one i got was...


Osmonics Desal AK4040TF Membrane,

maybe if it doesnt come down after pump might need a water softener.

[alanwilson]

I'd be really surprised if it doesn't come down, your water is hard but I have known of ones with higher tap tds getting low output below 010ppm.

let me know how you get on with the pump
