2015 Ellipse 42HD- Low water pressure

We are experiencing low water pressure both hooked up to external water and also using the water pump. Any suggestions?
Thanks, Don

How old is your water filter? On my coach, all water (shore or on board) goes through the whole house filter.

While we don't have a Winnebago product, our coach is the same when we use the whole house filter. We now filter outside before we the pressure reducer to get much better flow inside the coach.
I just found the whole house filter reduced the pressure to much.

I have a 07 Itasca Horizon with whole house filter and good pressures whether from pump or hose. Many newer faucets have flow restrictors/water savers that will significantly reduce the flow rate. If you have them, they can be removed and it might help some.

Your pressure issue won't be the whole house filter being as the filter is plumbed directly to the city water inlet first, so the on board pump does not run thru it. Is the low pressure in every faucet? If it's not then look at the screen in the faucets that are effected. Each spring no matter how well I flush the hot water tank in the fall I get calcium sediment stirred up and then the faucet screen plug and need cleaning to restore full water pressure.

Not true in all cases. Mine does. I was cleaning and replacing filters yesterday and turned pump on with filter housing off, and water did flow from filter inlet.

You could try removing the filter and replace the housing without it and check to see if that changes the pressures and flow.

Don A couple of things: cycle the valve that controls tank fill and regular use a couple of times with the city water hooked up, take a look at the screen filter on the water pump, and (get ready to get wet) with the city water and pump off take off the whole house filter and then turn on the city water and see if anything flushes out of the line ...

Let us know what works ... we all learn ...
