ro booster pump?

[d-maz]

I bought a used one off of RC and it does seems to boost anything. When I unplug it my production doesn`t seem to change at all.

Anyone know if you can rebuild these things? If not, and someone has one that they`re not using, I`d like to try it to see if it actually boosts my output. I`ll end up bringing it if it boosts my output.

I`ve had nothing but issues with my ro unit since I`ve bought it. My production is really low. I messed with it for a while and it`s finally giving me 000 TDS on the output, but it`s really slow.

Let me know what you`ve got.

Are you sure you need a booster in the first place? If you have city water, most municiple water services are sufficiently over 40psi so one would not be necessary. However, if you are on a well like me, you might need it.

Also, do you have a pressure gauge on your RO and if so, what is the ambient pressure without the pump? I would not consider running the booster without one as too much pressure is as bad or worse as not enough.

Dont forget that the rated production is at 72 degrees as the temp get lower so does production. Whats the water at now about 48-52 degrees. I have plenty of pressure and it took my 75 gal 2 1/2 days to fill and its a 75 gpd.

No, I don`t have a pressure gauge on the ro unit. We moved here 3 years ago and I noticed that the water pressure here is much lower than when we lived in Parma. I just figured that the pressure has something to do with it.

I know your production goes down when it`s cold out, but I put my output hose in a 5 gallon jug last night about 9pm and as of noon today it`s almost full.

I just changed my sediment, the 2 carbon blocks, and the DI on Wednesday. My membrane was brand new when I first hooked it up at the end of April last year.

Can you think of any other reasons my output would be so low?

If you have high hardness or dissolved solids in the supply water your membrane may be clogged. Do you have capability to flush the membrane with a bypass??

Just my 2 cents

It's the cold weather, Dave.....our water pressure always gets crappy here when the weather is cold....it slows down my ro/di too...

You can pick up an inline pressure gauge cheap from most places that sell RO/DI units. That would give you an idea on how low it is. Plus, you will need one to dial in the pressure on the booster pump, otherwise it can blow out your membrane. Also, this will let you know if it is working correctly.

I just got an dual inline tds meter with my filter order. When I first hooked it up I wanted to see where my tap water was. It read around 115, so I really don`t think my city water is to hard.

I used to have pressure meter that screwed onto a spicket. I don`t really know where it`s at, but I`ll try and find that. That should give me some idea.

I barely get 30psi reading on my guage. In six hours I get from 12-15 gallons on average.

You have to match the booster pump to your RO system. I have a 100gpd RO system and the old booster I had for a 35gpd RO would do nothing for the new RO. You need a pressure gauge to be sure.
Are you sure about your mains water? I had to get a water softner for my house (I have city water), I would foul a membrane in 2 weeks till I got the softner hooked up and a booster pump would do no good.
