Kitchen Faucet Water Flow

I have really marginal water flow at the kitchen faucet for hot or cold with city water hookup or pump. I replaced the original faucet last summer and that helped a little, but I think the flexible water hoses that move with the kitchen slide are the problem. I checked them today and find that they are 1/2" OD hoses....they must be only about 3/8" ID, no wonder the flow is so low. Have any of you on this board upped the hose size in your rig? The plex hoses are 1/2 ID so the flex hoses should be the same, don't you think?

Try taking out the water saver it's in the end of the spout, unscrew the little unit and try water with out it in and see if it increases. If it shows improvement then take the water saver out of the part then try it

Hi lhill,
The hose diameter is not the problem. The coach pump is rated for only a few gallons per minute. Is this the only faucet having flow problems? Try what nightriderrv posted. Where the water comes out there is an aerator. You may need a pair of pliers, to remove it.

I had the same problem

I had the same problem. I removed the aerator and it fixed the issue. The aerator was clogged with &%$$. I cleaned it up and reinserted the aerator and it works fine.

Good luck

First, what kind of faucet do you have. Is it the one piece with the single handle and the sprayer that pulls out of the end of the faucet? I had the exact same problem and tried all the remedies listed here and was about to buy a whole new faucet.

Check city water inlet valve, sometimes it can be blocked with debris, water filter, clean or replace, our water faucet make a loud vibrating noise when it was turned on, so then I took the faucet all apart with DW's help and after hours of searching finally found the offending part.

After taking it apart I finally found the problem, it was the 3/8 brass center tube (and this part is important) it looks like it won't come apart but it unscrews with vice grips. You can see, if you look carefully, a black o-ring in the middle of the brass tube that connects to the pull out sprayer hose. Inside I found a tiny black rubber part with a spring that had quit functioning, I took that out and I have water!!!

Please inform us of the outcome because I have found that people get support from these forums so they don't have to spend hard earned bucks at some repair shop to get it fixed. Thank you.

Practically every house or RV kitchen faucet I have had in the past several years has had some flow restriction. I have removed every fitting to remove washers with tiny holes, or remove most of the aerator parts, or drill bigger passage holes in some brass insert. If I'm going to put 6 gallons of water in my sink, why do the manufacturers or the Feds or the People's Republic of California require me do it sloooowly?

Thanks for all your replies.....
I did replace my Phoenix faucet this past summer with a Delta single handle faucet with a seperate sprayer and that made a noticable improvement with flow, but I still think the 1/2" hoses that go between the kitchen slide and the fixed area are the major culprit. I have good flow in the lavy sinks and shower but marginal flow in the kitchen whether I use the pump or am hooked to city water, no difference. I'm still thinking about whether or not I want to try to replace the flex hoses with ones that are 1/2" ID......
Thanks again!

My advice? Embark upon a program to eliminate every flow restrictor in your water system. Since your problem is apparently limited to the on faucet you should obviously focus on the plumbing to that fixture but I'll bet you the problem is with the flow restrictor in the faucet. I've even seen some flow restrictors that looked fine and still were clogged so badly hardly any water passed. Get rid of those silly things in your RV.

Also, if it is mainly the cold water that is running slow and if you have one of those ADC filters located under the kitchen sink or somewhere close by, it could be clogged up or used beyond its life expectancy.

They use that filter for water to the ice maker and the kitchen sink.

I took mine out completely and made a PVC bypass for it. I then installed a Culliagn Ice Maker filter for the water line going to the ice maker.

I don't use the kitchen sink water for anything except washing dishes.

If your coach has a Hydro-Hot, be careful and not increase your water pressure to over 1.5GPM, you will loose your hot water supply fast.

I have found on our Essex the main in line water filter is the problem with poor presure and volume. We started using less restritive water filters from Home Depot/Lowes. Last alot longer and alot less money. It's a 10 inch filter and 2 are about 10$.
