Low water preasure at kitchen Fauset

[Ricefarmer]

We have very little water pressure at our kitchen sink Fauset, on our 2020 Montana. Has been that way since day one. As soon as you turn it on it has ok pressure but within a second it drops way down? bathroom sing is fair as is the shower. Does it have a water saver? doesn't seem to have anything blocking it.
Any Recommendation's?
We're on park Water with plenty of pressure, have no control pressure valve installed.

1. Look at the aerator screen to see if it has accumulated some debris.

2. Check the for a disconnect valve under the sink and make sure it is fully on.

3. Take the whole faucet apart and clean the valves to remove any debris.

4. Look in the under belly for a kink in the PEX line

And check your water filter and control pressure valve

We have a 2020 3761 fl. Ours was the same way till we got an adjustable pressure gauge/ regulator and stashed the one that came with the camper. I set it at 45 psi and the pressure has been great ever since.

The first and easiest I would check is aerator.

Had the same issue, no problem anywhere in the camper except the kitchen sink. Sometimes it would get better for a short period of time if I toggled the sprayer on and off. I removed the faucet head and took it apart and found a small piece of plastic wrap stuck inside above the aerator that was in the plumbing system from construction.
Unthread the faucet head from the pull down and see if you get good flow, if so, start there.

yep did that already, pretty sure its the pressure regulator, the drain under the sink had a kink in the line from the factory. Convinced this coach was built on a friday afternoon. Just had to replace the Black Water drain release valve. It had a kink in it also, wouldn't close all the way.
Was a cheep cable, bent it trying to activate it. New cable is allot stronger.

[Ricefarmer]

Thank You will do that next. Where is the pressure regulator located on the coach?

[Jay & Bobbie]

My money would be on #4 above.
I would start by removing the rear panels of the basement and look around there first. The PEX water lines are a CF in there.

CF = cluster fun…I think…maybe cluster farm…cluster fish…cluster fit…cluster foot? That’s not it either. It’s a term that applies to a tangled web of pipe and wire that makes no sense how it got there. Cluster mess?

Oh Yeah a Cluster ****, now I understand, DUH Just like it was when I was in the Army in V. Nam.
Yeah everything is enclosed, just like the cable to my Black Tank Valve was.
Pressure is not great at the bathroom sink or the shower either. Im prone to think its a pressure Regulator problem if there is one on this Rig. might try to call Keystone (they haven't been any help in the past) tomorrow. I don't believe there is a filter creating the problem.

[rohrmann]

Pretty sure Keystone does not install water pressure regulators on any of their lines. Unless you bought this rig used and the previous owner installed one, there is not a regulator in the rig. Do you use a regulator when you connect at campgrounds? If not, you really should. I always use a heavy duty adjustable one, and even on our property where we are now, the community water pressure coming in is at 100 psi, so that is way too high for any of these rigs.

Be sure to check the "filter" where the park water come into the coach. I also recall there is a filter at the connection of the faucet hose to the Pex lines. Check those also

Thanks, we bought it New in 2020, Mdl 3740 FK. pressure here is city water supply , good pressure at outlet supply, called Keystone this morning, no help, as usual, said to take it to a repair station, Could be the 2 way valve or check valve, ask them for a schematic for location, said they can't do that.

Thanks will try to locate a filter, it must be burried inside.

WHAA-LAA!!!!! found it. It was a pressure regulator that Camping world had put in after we bought the Rig. Dumb me I forgot about it. Was a 40-50 lb regulator. Took it off like magic we have pressure for the first time. It must have been faulty.
Thank You everyone for the help.

[rohrmann]

If that 'regulator' looks similar to this, it is nothing more than a restrictor, not a real regulator. Best used as a fishing weight.

[Trevor]

I agree. That was the culprit in our case also. We had the same problem. No pressure at the kitchen faucet , but pritty good everywhere else. I put on an adjustable one set at 45 psi and now it’s all good.

yep verry similar
