Low Water Pressure

[dmanhart]

Water pressure ( at all faucets) is the same, regardless of using city water connection or the pump. City pressure and pump pressure is more than adequate.

That's a tough one; a single problem that causes low flow at all your faucets on both city and on-board water. What model and year is your Montana? Is pressure low on both hot & cold water?

[dmanhart]

Yes, hot & cold side. It’s a 2010 Montana, 3455 SA. It must be some type of blockage immediately following the point where water from the city inlet & the pumped water enters the distribution system..

[scottz]

I don't know how your system is configured, but attached is a drawing of mine. I can't think of a single problem that would account for all of your symptoms.

probably simple solution. go outside and clean the screen at the intake.


if you have a water softner, pressure gauge and/or filter system remove them and clean them. test water flow without these things on.

Oh yeah, check too see that there is a good flow at the rv park:-)


I JUST NOTICED THAT THIS WAS A THREAD BACK IN 2018---I hope you've figured it out by now.....

[dmanhart]

Been there, done that. I have full pressure going into the spaghetti distribution complex, with or without pressure regulator, water filter, backflow preventer, low-flow restrictors, etc. etc. The pump outlet has good pressure when disconnecting it prior to the distribution complex. Something has to be restricting the flow within the distribution complex.
How do I find that thread from 2018?

This is it. It started back on 2/10/2018.

It must be something that is common to both city/on-board/cold/hot water; weird problem. You sure your just not expecting too much? Mine works fine, but pressure is not great; always been that way. I'm just happy to have running water.

Yes, thread started in 2018, but he tacked his problem on yesterday. Trying to help, but without being able to put hands on I'm out of ideas.

[dmanhart]

Oh, ok. I read all the posts. Just Didn’t realize it started in 2018. I seldom look at dates.

No problem; your question is relevant.

[dmanhart]

GOOD NEWS: The problem is solved, if only temporarily. I disconnected the water inlet (backflow preventer had been removed earlier) and blew 125 pounds of air pressure into the kitchen faucet hose (faucet open). Apparently this dislodged something in the distribution system because now I have good pressure at all faucets throughout the RV. Nothing but water came out of the water inlet so the blockage may occur in the future. For now, I am a happy camper !
Thanks to all for your comments and suggestions

scottz, I just noticed that it was you who initially posted the question of low water pressure. I quess you got you issue fixed:-)
