Water pressure problem

[Nicodemus]

We have a Prime Time Spartan. The water at the kitchen sink is a dribble, and the water flow at the bathroom sink is only slightly better. However, the shower has great pressure. I can't figure out why this is so or how to correct it. We use a regulator because the manager said that the pressure is high. Any ideas?

One more thing on the kitchen if it has a pull out head (Faucet head is also sprayer) there is a check valve in the base of the head (where the hose connects) this can lime up and clog.

Another angle to consider when addressing poor water flow, I seemed to be constantly cleaning lime and calcium deposits from the faucet aerators until I finally installed a water softener on our coach. Problem solved.

There is no such thing as a "restrictor" sold as a pressure regulator. Those cheap barrel shaped regulators cannot be tested by checking flow at the end of a garden hose, the flow will vary because of different amounts of restriction in the various fixtures. Just buy a quality regulator.

What do you mean by "regulator"?

If it's the $10 variety you connect to the (hose bib) faucet - it's really a water "restrictor".

If it's a Watts Regulator (or the like) - about $50. - you should be able to adjust the pressure at the regulator.

Test your "regulator" on a S&B (home) hose bib with a garden hose.
See what kind of flow (volume) & pressure you get.

You should define what you mean “take the top off the faucet”. At the end of each faucet spout where the water comes out there is a small screwed in device about 3/4” in Diameter, that is the aerator, inside it there is a screen that catches the small debris that collect in the piping. Use a pair of pliers or a pair of Channel locks padded with a small rag to prevent scratching the aerator and rotate out (righty tightly and lefty loose/ you are looking at it upside down. Blow it out and re-install. Or go to your local hardware store/ Lowe’s/ Home Depot and purchase a new one only a couple of bucks each.

The water pump has a built in check valve to prevent water from flowing back into your fresh water tank when you are hooked up to city water pressure.
My guess since your water flow problem in common to all of your hot and cold faucets, that check valve must be stuck and severely limiting the amount of water getting into your hot and cold water lines.
Easy way to check this is to disconnect your outlet water line at the water pump and see just how free flowing the water is comming out of your pump.

Yes, we're using a regulator and park water. Was going to take it off park water but discovered that now the water pump isn't working! Just one thing after another.

Are you using a pressure regulator and park water? is the regulator a 3/4" cylinder either plastic or brass with male hose fitting at one end and female at the other.. THOSE ARE JUNK.. Upgrade to either a Valterra adjustable (About 30 bucks) or a Watts or Zurin in-line 1/2 or 3/4 inch with hose adapters (about twice that).

All good suggestions ! Try to just remove the screen at each faucet and run the water without the end on and see if it comes rushing out. Every time I have had a low water issue in the rig and the pressure is good outside its been a clogged screen at the water inlet where the hose attaches to rig or at the faucet or the pressure regulator outside on the hose,

[Nicodemus]

Thanks for the input everyone. I shall attempt to remove the kitchen faucet top and see if the screen is the problem. It affects both the hot and cold water. Not using our tank but I should check to see if it does this when on the pump. Should I disconnect from city water first? We didn't have this problem in the prior park, so I don't think it's a design defect. Unfortunately the bathroom sink is not the kind you can unscrew so I don't know how that will be fixed.

I wish I knew the answer or how to correct this problem. I have the same problem and yes I have cleaned the screens and have replaced the screens and cleaned out the washers in the valves. nothing has worked. the answers you got above are just the tip of the iceberg, just the start of going mad trying to figure this out. I'm beginning to think it is an engineering design

Check the strainer on the water pump if you are using water from the fresh water tank.

Are there water filters on the lines feeding these 2 sinks? Our galley sink has one, but I don't think the bath one does. Aerators (clean/replace) are a good place to start.

Is water pressure low on both hot and cold?
