Ro/Di question

[psycho]

Ok I just bought a 6 stage ro/di and I get it home to hook up and it says in the directions " for the ro/di filter to preform to the best" you should have 100 psi of water pressure! the lower the water pressure the lower the quality of water. I asked my husband about our water pressure because we have well water, and he said our water pressure is only 50 or maybe 60 psi is this going to be worth my time hooking this thing up? or should I try to get my money back? :notsure:

If you have a well, then you may be able to change the pressure switch out in the jet pump to up your water pressure, provided your storage tank can take it.
Alternatively, they sell RODI feed pumps that boost the pressure.

the typhoon model i have from airwaterice has a lower pressure rating than some of those on the big auction site, max pressure is 75psi on mine, my house is like 72 psi and it works great!
Unless you run a booster pump not many homes have 100psi water pressure.
Might be worth looking into returning that and buying 1 of the airwaterice models?

Water pressure will not affect the quality of the water coming out. The only thing the pressure will affect is how much water you can produce per hour. If you have a 100gpd Ro/Di then you won't get 100gpd but maybe 70gpd. HTH.

There is no way you want you water pressure that high in your house and it's against code in most places to run pressure that high......That is why if on city water around your meter you have a pressure regulator that is set....Pressure that high will take it's toll on your plumbing system and your appliances as well....100psi is really high and usually around 75psi is tops......You can purchase a booster pump with pressure regulator if you like to boost the pressure, but even then I wouldn't try to overpower it....I like to run around 60psi on my unit......

oh....ok thanks for all the suggestions! :joy:

the water psi is very important on a ro/di, i researched this before purchasing and also called airwaterice, on my model anything over 75 psi can cause issues with the membrane and anything below I think it was like 45 psi can cause issues with filtration, basically not enough pressure for the filters.
I would make sure you have enough pressure for what the unit is recommended and if its something crazy like 100psi then i would return it and buy something thats more for home use.
JMO...

Incoming water pressure is important, water quality being fed the unit also important, and water temp also important and all play part in how a unit will produce......Bottom line 100psi will definitely blow things apart....I'm pretty sure if you look at any of the housings really close you'll probably find some type of pressure rating listed on them and it probably won't say anything near 100psi.....I think most membrane housings only say 75psi.....
