This is a weird one. I connected to city water, turned it on, came back in and found the toilet bowl overflowing. Ran outside and turned off the water, flushed the bowl and then turned the water outside back on. It only did that the one time and there wasn’t any leakage coming into the bowl after I turned it back on so I’m curious if any of you know what might have caused this. I don’t have a black tank flush system and that tank was not full either which I saw on another thread, my water pump was turned off, and just strange thing.
 
This is one reason among dozens to not use shore water.
Use your consistent internal pump.

Without you telling us of the 160psi shore pressure(highest I've encountered. SLC KOA) we don't know what's what.
We can only guess that your toilet valve wasn't seated. This is common and possibly unrelated to shore water. Just coincidental.

I do have a pressure regulator but not one with a gauge. I did notice the city water system seemed to fluctuate pressure because at times my connections would drip, then at other times no drip.
 
Pressure regulators are inconsistent over time.
Get one with a guage in case the regulator goes/is bad.
Your toilet could all be unrelated.

There is no reason to ever chance shore water.
 
Or it could have been the valve not fully closed due to either:

The foot pedal not sprung back to the closed position, or
a piece of garbage (plastic shaving) caught in the valve.

Flushing the bowl would have resolved either of those issues.

That must have been what happened so I’ll be watchful of that now. I have a wet bath so cleanup was not hard anyway.

Hi friend get 1 with a gauge.
I make sure ubder 65.
My brother said no need for 1 and one days water leaking everywhere front under rig.
I still have no heard the reason!

If we knew the reason, then we could try to make sure it doesn’t happen again, right? So annoying! I think of just filling and running off my water tank but then that will wear out the pump faster maybe. RV fun stuff and I am such a novice even though I’m over 70!
 
That $39 to $90 pump will probably outlive you.
If the pump does fail it's two handtight water connections and a snap on electrical connection AND you'll have the shore water in case of DIRE emergency.

There is no reason to ever not choose the pump and tank over the land water.

Use the experience you've had.
Had you not been there... THOUSANDS OF GALLONS LATER...

Mold is more expensive
 
My water pump was $70. Considering how relatively inexpensive a new one was, I bought one and carry it as a spare... 10 minute replacement.

Remote camping with a full tank of water but no way to pump it is not a movie I want to watch.

P.S. NEVER connect to a water source of unknown pressure. Get a quality ADJUSTABLE regulator with a GAUGE. Busted plastic pex elbows will be your worst nightmare!

I NEVER use city water anymore... It's used to fill the tank and gets pumped at a known pressure.

I have a spare pump but I haven't been carrying it.
It's something I overlooked.
I'm putting it in the rv right now.
Thanks.


Thanks to all of you for your suggestions and knowledge. Makes me rethink using the water pump and just filling the tank when needed. My rv is small which means everything is in tight spaces and no, I don’t want broken pipes!
 
Another vote for using the water pump. On my rig, I an intermittent failure of the check valve that separates the city water from the pump water. When hooked up to city water, it sometimes fills the fresh tank. I use the pump water until the fresh tank is empty, then hook up to city water. If it fills the tank, no problem, I switch back to the pump. If it doesn't, again no problem, I use it as it is. It is now just my routine.
 
I've used city water for years and have never had an issue. It should be a non-issue if you use common sense and are properly prepared vs worrying that the worst is going to happen.


1. I always turn off city water when I am outside of the coach.

1a. I always shut off the water pump when I'm not on city water and I'm not inside the coach because you can still pump out 50 gallons of water into the coach..... and 50 gallons of water will do as much damage as 500 gallons. At least with city water someone may see the water pouring out of the coach and run over and shut off the city water for you. If your coach is locked and the pump starts running, the water won't stop until the fresh tank is dry. And I do carry a spare water pump.


2. I always use a pressure regulator with a gauge..... and I always carry a spare.


3. If the coach plumbing does not come with a quarter-turn shutoff valve for the toilet, I always install one in case the flush valve fails. This way you can still use the toilet until you can get it fixed by turning the water on and off at the toilet.



Its not rocket science..... its common sense...... and this thread is almost bordering on the threads where people post they won't flush toilet paper into their black tank! :rofl:

Seriously just fill the tank.
AND
Believe me we try to remember to shut the pump of if out.

Also my brother hooked to his water at home and late working relatives noticed water pouring from the bottom of his rig.
Never found the reason but fresh tank was full!
