Fresh Water Tank Question

My drain valve is broken and I want to instal a new hose connection between the water pump and fresh water tank. The water tank is pretty full. Will water spray everywhere if I disconnect the old hose between the water pump and water tank?

The water that's in the hose, will come out, but not under any pressure.

But you should also find a "strainer" that is in that same water pump input hose line. Make sure you check it as well, as they have a little bit of a habit of having a small crack in them. That crack will not leak water, but it will allow air to be sucked in by the water pump, suggesting that the water tank is empty.

Thanks, Andy. As you deduced, I'm troubleshooting a problem with my water pump. My pump (which is brand new) never shuts down when the switch is "on." It always has a low grumble.

The hose (which is black and looks original) connecting the pump and fresh water tank has a strainer (like you said) and the fresh water tank drain valve. Is this normal to have the drain valve configured like this? I'm thinking about bypassing the drain valve and connect the hose directly to the fresh water tank.

What brand water pump?

Usually, when a water pump won't completely shut off, it's a sign that it's built in (if it has one) check valve is leaking internally. When it does that, the pressure cannot get to maximum, and retain it as well.

Your setup may have a "input side" check valve as well as one on the output side. If not, you can install one, on the input side.

That would stop the "back flow" of water, that is from the pump, back into the water tank.

Andy

Related to part of this issue: I broke my cheapo plastic/nylon drain valve again when I was preparing to winterize the trailer. The danged cheapo valve has a very short life before it gets brittle and the handle breaks off in your hand.

Andy, do you know of an aftermarket valve (this is the one that is mounted to the frame between the wheels)? I'd love to find a brass valve or something like it.

Thanks - Pat

I sure hope that you get an answer on this one, as I have the same issues with the cheap plastic drain valve.

water tank drain.

Pat.

I will check into it tomorrow, when I am at the office, and likewise, will post the information.

Andy,
My pump is a Shurflo.

I put this drain valve together with parts at Lowes. I just took the old one with & made sure the threads were the same. It's all brass.

To me, the Shurflo is the problem.

Sorry, but I have never cared for them.

Top quality, was the Peters and Russell, and now the Jabsco. Sure they cost more, but they only last about 25 years and then you have to replace the valves. WOW. How terrible.

Probably installing a check valve on the input to the Shurflo, will fix the issue with yours.

Andy

Okay, this afternoon I isolated the problem to the strainer. I bypassed it and I had good pressure. I confirmed this twice for good measure. The strange thing is, the strainer looks fine. Those hairline fractures can bite you.

Is there a way to adjust the water pressure on my Shurflo?

I will not be in my office until Monday am.

Jabsco has 2 basic models.

The cheapest one, more that satisfies the pump requirements for and Airstream, including your Excella.

The next one up, is very expensive, and would be an "over kill" for your coach.

The original pump that was in your Excella was made by Peters and Russell. Parts as well as some repair kits are still available for them.

If you still have the old pump, a rebuild kit would probably make it last another 25 to 30 years.

Andy
