Help This Rookie - No Water Pressure

I have a 2014 Jayco 29 QBH. I am trying to de-winterize the trailer for our first real trip next weekend.

I have filled the fresh water tank with water, turn the water pump on and then open faucets... It sputtered out a little bit of pink but now nothing... The fresh tank is 2/3rd's full.

The pump is supposed to turn off at 45psi but it just runs continuosly and the fresh water is not coming out.

I installed the hot water tank drain plug but I am not sure where else the problem could be?

It just doesn't seem like the pump should run for 15 minutes trying to get the water into the lines?

My trailer does have a hot water bypass but not sure if it needs to be open?

Help, lol.......

Try this, Shut the pump off. close the bypass on the hot water heater and open the main line input and the main line output on the water heater. There should be an access panel to get to your water pump. There may be a winterization bypass on that at well. One to a open hose and the other to the main water intake from the fresh water tank. make sure the fresh water intake is open and the bypass hose is closed.

Now close all the faucets, and make sure the outdoor shower is closed (if you have one).

go back in and turn on the pump. It should pressurize and fill up the hot water heater, then shut off.
Then go back and open the faucets one by one (Hot then cold) and close them till they flow freely.

Thank you for your reply. I have two bypass locations that I can find.

#1. Is under the kitchen sink. It's the shureflo pump. There are two valves. One that looks like it leads from the plumbing and another that is a clear open ended tube.

#2. Is behind a panel behind my water heater. There is 3 valves here A B C as per the manual. The water heater looks bypassed at the moment.

I will try what you stated but not sure when the valve is open or closed? I am assuming when it's inline with the pipe it's open. right?

Yes, when it is inline with the pipe it is open.

The one under the sink is the same.

The bypass under the sink. The valve that leads to the plumbing is the pick up from the water tank. The one that leads to the clear tube is for winterizing.

Also, make sure your low point drains are closed.

Also make sure your low point drain lines are closed.

Hey Guys,

That worked. It was the valves under the kitchen sink on the shureflo. However, this has created a new problem for me. The water heater drain was leaking so I pulled the plastic plug out and went to put it back in and it's stripped/cross threaded to holy heck. Why on earth would they use a cheap crappy plastic drain plug? Is this something that can be found at a local hardware store?

You should be able to find a replacement drain plug at most hardware stores Keep a spare better to have the plastic plug cross thread than to have the heater cross thread You could also use a brass plug if needed

Your water tank is likely to be made of aluminum. Do not use a brass plug as it will corrode. Walmart and most RV supply places have the plastic plugs.
