Kitchen Sink Question ?

[pudgybear]

Hay! any plumbers out there today? quick question for YOU, I have low pressure and LOW volume at my kitchen sink, my question is: will the volume increase IF I put larger pipes to the sink, for instance I now have 3/8" should I increase to 1/2" ? thanks Bob

Not a plumber...but did stay at a holiday inn last night......before doing anything pull off the aerator (the screw on screen thing) at the end of the spout.....chance it could have sediment that is restricting the water flow/pressure.
To answer your question...larger pipe will increase volume....BUT faucet won't likely take advantage of increased flow to it such that only so much water can pass thru the control valve....3/8" would seem adequate as most connection lines are not any larger....

Not a plumber and slept in my own bed. Used to have occasional flow issues at the old house due to debris catching in the shutoff valves. So no, 3/8 should have decent pressure, I would also check or replace the supply valves under the sink.

Do you have decent pressure everywhere else in the house ?
if so, then I agree with the others,,

One of the faucets where I work had very low flow due to mineral deposits building up inside the faucet. They put a rebuild kit in it and everything worked fine again.

I am a Plumber and these fellows are giving you fine advice.
The most common problem is a plugged up aerator on the end of your kitchen faucet spout. Remove it and turn the water on to flush it and to see if that was indeed the cause.
Doubtful that increasing the lines will help because the average faucet throttles the water down to about 1/4" openings anyhow.
If it is not the aerator then start working on the rest, but definitely start with the aerator.

On a house I built a few years ago, the kitchen sink had low pressure/volume even without the aerator. I complained to the plumber doing the install, he showed me that it had some kind of backflow preventer built into it. He took a pair of pliers, twisted and pulled until it broke out, and then it worked fine.

Next house the new faucet didn't have that problem, don't know if that was a code change or manufacturer change or what?

If you have shut off valves under the sink turn the water on at the sink and open and close the valves a few times. Did this in a rental house and flow increased. They get built up with minerals. However if you never turn the valves on before they may be frozen open. Be careful they do not break.
