Toilet not flushing!
 
14 month old Ď20 ORV Backcountry 21RWS
Havenít used it for 2 months. When preparing it for this trip I noticed that the water pump had been left on. With water in the tank I figured it wasnít a problem with plenty of battery power. from solar. The faucets and shower work so the pump must be OK. When I step on the toilet arm halfway to let water into the bowel it makes a little noise and a tiny dribble comes out for a second. Itís like itís plugged up or the valve is only opening a tiny bit.

Guess Iíll just use a bucket to fill it.

Without disassembly of the valve it sounds like youíve nailed it - and youíve got a work-around. 😀

It would help to know the make and model of the toilet.

It could be the vacuum breaker or the flush valve.
I assume since you could fill it with a bucket and flush, the ball is operating correctly.

On some you can change the vacuum breaker without pulling the toilet, on some it is all one unit, and the toilet needs to come out.

Yes, the ball is fine. After being gone all day I gave it a nudge. Again a little noise and a dribble which continued for 5-8 seconds after taking my foot off. Donít see a make on this unit. Itís a One Humper I think.

Thank heavens the CEO isnít along or this would go from bucket brigade to 911!

Pull the water lines off. If water comes out well the valve on the toilet is bad. Common failure.

I don’t think it is the valve now. The lav faucet is only putting out a pathetic dribble, too. The shower and kitchen faucet are working fine, thank God! There must be a blockage in the water lines to the lav and toilet. That probably means removing the plastic on the bottom of the trailer. Doesn’t sound fun.

take the airerator off the lav faucet.. see if it runs.. We had a piece of plastic from the tank find its way to the shower cold water side after 6 years of ownership.. At 16 years old we replaced the shower faucet as we had removed it to see what the problem was.. who knows what the factory leaves in the tank when it is shipped out. There could be a filter screen in the water line where it attached to the toilet.

"take the airerator off the lav faucet.. see if it runs.."

How would that affect the water pressure at the toilet? Whatever is restricting the flow to the lav and toilet is not affecting the kitchen faucet or the water heater (I think).

I think the theory of something that was left in the system at the factory which has broken free and jammed somewhere seems most likely. I'm going to ask on the ORV forum about getting a plumbing schematic.

Process of elimination!

RV water lines are 1/2" PEX
Water lines have connections at each sink, shower, toilet that can be disconnected and flow checked...no need to remove underbelly cover UNTIL actual problem ID'd

Remove the Lav Aerator and check flow....clean up aerator
THEN if flow is good----turn off water supply and remove toilet water supply line (some have a screen on inlet)
Place toilet water supply line in bucket and have some one turn water on...OFF
Good Flow then Toilet water inlet valve is issue



***Pump ON---only RUNS when a demand for water occurs
Faucet OPEN or leak

Gammel 08-03-2021 12:24 PM

But no flow at faucet AND toilet tells me the problem is upstream of where those lines diverge. I don't see how that can be accessed from above. I did remove the lav aerator and there was 'gravel' in there which is likely hard water deposits. We have very hard water here so I'm thinking the faucet and toilet valve could have enough deposits in there to cause the problem although I have a hard time believing it would shut both off. The simplest first step would be to take the lav faucet apart and examine it.

I asked on the ORV forum for a water system schematic and the mods accused me of 'cross posting'! Give me a break!

Old-Biscuit 08-03-2021 12:38 PM

OK then...........

Gammel 08-03-2021 12:38 PM

I just reached under the lav to remove the PEX lines to the faucet and even with the pump off there is considerable pressure and water started spraying out! Gotta figure out the low point drain I guess. That pressure does rather support the hard water deposit theory.

Gammel 08-03-2021 12:58 PM

What kind of toilet is this?
 
And how do you disassemble the valve?
I see nothing obvious about getting the lever off to begin.

Backcountry 21RWS if that helps.

Gammel 08-03-2021 01:13 PM

I took the lav faucet apart (quite the marvel of Taiwanese 'value engineering'!), and there is no sign of hard water deposits in the valve. The problem has to be upstream. I will have my CEO/assistant turn on the pump for a second to check the flow from the PEX lines before re-assembling it.
