Bathroom Cold Water Pressure Problem

I have a 2016 FR3. When hooked to city water, both the hot and cold water pressure is fine in shower and kitchen sink. In the bathroom the hot water sink pressure is fine, but the cold water barely comes out. Toilet water pressure is also fine. Any suggestions???

If the hot water is fine and cold not you may have some debris stuck in the valve secure the water drain the pressure and take the valve apart and blow out or flush to remove debris.

Batrhroom Cold Water Pressure Problem

The hot and cold water come out of a single faucet. That's what has me puzzled. We have removed the faucet "screen" and cleaned it. I'm not sure what you are suggesting that we try. Can you clarify?

You may have a single faucet, but there are still 2 lines hooked to it, one hot, one cold. There's crap in the cold water line. Disconnect it and clean it out.

If you post a picture of the faucet, we can tell you how to take it apart, to flush out the apparatus where the cold water flows in. Also, look beneath the sink to make sure the cold water line is not kinked.

I would suspect that the pressure is actually fine everywhere, but there is restricted flow to the cold water side of the faucet.

Take the screen off the end of the faucet. It probably has something restricting the water flow.

Seems like this would restrict both hot and cold water... but the OP said "hot water sink pressure is fine, but the cold water barely comes out".

If that was the case the hot water pressure would be low too!

Try this first, shut off the water faucet by closing the two stops below the sink.

Disconnect the cold water hose at the bottom of the faucet.

Get a bucket and put the water hose end in the bucket and turn on the stop. If there is crap in that hose this should blow it out. It should also show you if you have good pressure. If so, the problem is in the faucet itself. If not the problem is in the water supply to the faucet int he camper system.

Im betting the problem is in the faucet itself.

The fast easy solution, but a new faucet at Lowes or Home Depot. Their residential faucets are far better built than the cheap plastic crap the RV manufacturers install.

Buy new flex lines as well, that way you will greatly lessen the instances of leaks with the new installation.

New Faucet & flex lines

Here is an example of the type of thing I am talking about:

https://www.lowes.com/pd/GROHE-Glouc...ain/1000333813

Not expensive and has cartridges not washers for longer lasting more even water flow. I like the braided steel lines. They last longer
