Do you know for sure the water pump is applying pressure---can you test it? Is the source providing adequate water---like from the tank to the pump. Kink in a hose? Do you need to have more air in the source so as not to have a vaccum effect---anything clogged---like a vent? Just some Ideas the kind I would have if I was there talkin' to ya-----good luck I'm sure a more techinical person will respond.

When I fill my fresh water tank I have to open a valve. If I don't close it after filling I have no pressure.

Do you have water filters and if so then have you tried it without the filters. There are several different microns of filters and if you use the wrong ones you will bring the flow to a standstill.

Hi Tony.langdon,
Welcome to iRV2. Not knowing the coach you own this these are some things you can try.
1. Is the water pressure problem the same when you source water from CG water or coach water tank? If yes, the valves mentioned in #2 need to be checked.
2. If the problem is only with coach tank water consider ensuring all the valves are correctly positioned to allow the pump to work correctly. These valves can be the fill, winterizing and HWH bypass valves.
3. If the problem is only with CG water source, the filters mentioned by Mike Canter is a good first step. Try without and with filters.

What most people call lack of pressure is really a lack of water volume. The standard pump setting is 45 psi and that's plenty of pressure, but restrictions in the lines, faucets, shower heads, etc. can reduce the amount of water (flow or gallons per minute) to unacceptable levels. Water filters are one common cause - the finer the filter, the less water passes through. Clogged screens on the faucets and flow restrictors in shower heads are other common causes for this complaint.

I don't know the age of your coach, or whether or not you have been in the habit of using filters, but your faucet fixtures themselves may have accumulated calcium or other hard water deposits that are restricting the water flow. Is it in all sinks, toilet etc? Is it worse in the bathroom sink than the kitchen?
