Issues with ro/di

HI there.

We received a new aquasafe unit yesterday. And just put it in place of the old one. I have maybe gotten 15 gallons since last night. And considering it is a 100 gallon per day unti i don't see me hitting that mark. What have i done wrong.I see it going through everything but it is an obscenely slow trickle.

I also sent ed and email as my first di cartridge is already black!!

Don't get that either.

Any suggestions?

Thanks
Craig

I believe the flow rate is determined using warm water and at a increased PSI, some units have this info included. The colder the water the slower it works and the same for city pressure.

You can get a booster pump if you wanted and I used a long piece of inlet hose and coiled it up in a salt bucket with warm water and a heater, to warm the water going in the unit. I just did this to originally fill the tank. Other than that the slower rate is not an issue for me.

Not sure on the DI cartridge.

Okay so yes the water coing out is pretty cold as it is hooked into my cold water supply.. So how do i hook it up so i get warmer water?

I don't think you can, you don't want it coming out of your hot water tank.
You could do what I did but that's not really a long-term solution.

Okay we'll i dunno but really i am getting a little irritated

Considering they advertise this thing to do about 4 gallons and hour when it is not freezing outside i don't get it.

It is hooked up to my cold water pipe but how can you control the temp of that? YOu can't. And my god it is pretty warm outside ...lol

Is there anyone in Calgary with one of these units that can either send pics or pop by to see if it is hooked up right?

As there instructions are so lame you can't really make sure it is running properly or not.....

grrrrr.

Sounds like you need a booster pump. OR you have a lot of stuff in your water. Typically an RO unit produce "good water/bad" in 1:8 ratio using house pressure alone and 1:3 using a booster pump.

We'll the problem is that i had another r/o hooked up the same way and had no issues although it was less gallons per day.

The new thing is i have now put 20 gallons through it and 2 of the 3 di are now black. So out of 20 gallons that exhausted 2 of my di resins. The tds in Calgary isn't that bad....

Apprently something is not right...

the easiest way to run warmer water through is to use the faucet adapter instead.

Hey i have your hose to. I will drop it off today

But the problem is now that the di cartridges are now black already. I ran it all night long and they are now all black. I don't get it ...

be careful, running water that's too hot through the membrane can damage it. If you do want to warm the water up, you can get 20 or 30 feet of tube, coil it up and put it in a 5g bucket of warmer water, this should increase the temp a bit.
The other thing to check first is your feed water, what PSI are you getting? If memory serves, they want a minimum of 40PSI, with 60+ being recommended.
