View Full Version : House Water pressure

FYI.

I did some construction on my house and the plumber suggested that I could improve my water pressure by changing the "globe" values before and after the water meter with "gate" values. I think they are gate values. It did improve my water pressure by about 6 or 7 PSI.

Then the water company came to test the backflow value, which is require for in ground sprinklers. It was clogged. They cleaned it (no charge) and that improved the pressure by another 3 PSI.

The RODI unit is getting about 52 PSI now.

I hope to show up at meetings again. Back to Reefing after house renovations.

When I was in Mineola, my avg. pressure was about 60 PSI. Then I moved up to CT and my avg. pressure is 90 PSI now.

Water production is twice as quick :)

Bethpage water pressure is about 54 PSI according to the water company.

Should I still get a booster pump

I'm in Hicksville, and even with making RO/DI water for the tank, and RO only water for drinking, my water bill is still only around $8 per quarter (3 months). Regardless of water pressure, at that price, a booster pump doesn't seem worth it to me. Just my opinion.

$8 is outrageous!
Even in Mineola, I was paying about $75 every 6 months.

Up here in CT, it's $150 per quarter :(

Kilroy do you live in an apartment and never shower, or are you just missing a digit in that $8 estimate?

Better than that, I have a roommate who pays for half of it! hehe... $4 every quarter isn't so bad. :)

I think I pay 20 or 30 for a quarter except for the summer months.

I just wanted faster water production,

A booster pump will fit your needs for faster water production and less waste water. 80-90 psi is the ideal range for R/O production.

Is that 80-90 psi irregardless of the type of membrane that is being used? Is saw on another post that 50 psi is recommended for a Dow Filmtec membrane. Would I be okay boosting that to 80-90 psi for the filmtec?

I thought 60 psi was the target number but a RC sponsor recomends 50 psi

This is from BFS (vendor)

How much water pressure is needed to run an RO or RODI system?

The amount of pressure needed is dictated by the RO membrane. Factory specifications on our 50, 75, and 100 gpd systems call for at least 50 psi; and on our 150 gpd systems, 65 psi. You might get away with up to 10 psi less than these specifications, but be prepared for decreased performance in terms of how much water the membrane purifies, and how efficiently it performs.

We recommend not exceeding 90 psi. There are components in the systems with maximum operating pressures of 100 psi. At 90 psi you can expect exceptional performance from the membrane. If your line (plumbing) pressure exceeds 90 psi, install a pressure regulator (see www.buckeyefieldsupply.com) to reduce the pressure. If you would like to increase your line pressure (in 50, 75, and 100 gpd systems), install a booster pump.


Notice the phrase "At 90 psi you can expect exceptional performance from the membrane"

The membranes can handle well over 90 psi, but jacking it up higher isn't recommended because of the pressure limits of other components in your system.
