Water Pressure
I've had our 5th wheel for a little over a year , and we've always had to use our fresh water tank for water at all the sites we've been to. We have reserved several full service hookup sites on some upcoming trips, so in preparation of that I hooked up to my outside hose bib at home, and went to the City Water switch position. I've noticed a considerably lower water pressure when I turn on the inside faucets in the 5th wheel. Is this normal? When I'm pumping out of the fresh water tank in the 5th wheel, the water pressure is great. With the water coming out of my outside hose bib, it is about 1/2 of the pressure that I get. Anyone have any answer for this, and yes I have a water pressure fitting ahead of my incoming water into the 5th wheel.

When you say water pressure fitting what type? The cheap in line type do not regulate pressure they just restrict it. If your water pressure is o.k. at the spigot I would remove that fitting first.

One reason that comes to mind is that your freshwater tank has a pump, which I’m sure helps a lot with pressure. Pressure from a hose, from city water, is going to be whatever pressure is coming from the spigot.

Get one of these... https://www.rvwaterfilterstore.com/F3003.htm
The cheap one's are a waste of money and time...

You can always run your pump at full hook up sites too. I sometimes do that since the pressure at many of the CGs is less than optimal.

Tbos,
Not having a schematic of the plumbing makes knowing how the plumbing is installed and what goes where very difficult. My thought was since the pump pulls water out of the fresh water tank, and with it being empty it would burn the pump up. Does anyone have the plumbing schematic for a Avalanche 365?

you would have to have water in the freshwater tank for that to work. Easiest way to describe it (depending on valving) is there is a T in front of the pump and a one-way check valve in the pump to prevent filling the FW tank when on city water..
Using the pump would or not increase the pressure to the pump's pressure if the CW pressure was / is less... That's why I use a regulator capable of being adjusted for the circumstances and with a flow rate higher than the trailer's plumbing..

If you wanted to run the pump you would have to have water in the tank. My rig’s valve slowly fills the tank at the same time so it’s not a problem for me. It’s not supposed to do that but until it’s changed I can’t do anything about it.

These 2 are NOT regulators, they are restrictors & regardless of whether they are "hi flow", 50 psi or whatever they restrict the flow to reduce the pressure.
This & the link Javi added are "regulators", usually preset at 50-55psi which is a good pressure & safe for your rv. If the pressure at the faucet is less than the preset it will NOT affect the pressure/flow, it also will NOT increase the pressure, but if the faucet pressure is above the preset it will "regulate" it to the preset not restrict it.
There are 2 items I connect EVERY time I park, #1 surge protector/ems at the power pedestal & #2 the water regulator at the faucet, not at the rv. The reason you put the regulator on the faucet is your water hose is probably not rated for as high of pressure as the rv plumbing, thus you're protecting the hose also.
We've been to parks with VERY low pressure, 30-35 psi, at these we fill our tank & run the pump, they are usually set between 40-55 psi & to several that have had 100+ psi & at those I wouldn't trust that restrictor to protect anything.

There are a few different brands of regulators available. Valtera make one and so do Camco. The Camco is available from Walmart online and is cheaper than the Valtera one. It's not available in store, you have to click n collect it.

Many to choose from. I got the renator brand based on reviews. It came in a nice box with form fitting foam that I use to store it. Very protective of the gauge and all.
