Our toilet has backed up on our 2013 Itasca Motorhome. We just purchased and each trip we've gone on this has happened. We used a plunger each time. We were on level ground. Any suggestions on possible cause?

What type of toilet is it? Sunmar, thetford, Dometic,Aqua magic, Sealand....?
porcelain or plastic?
Foot pedal or side lever flush? Is the valve opening to allow the waste to drop into the tanks?

Lots of questions need to be answered! Might just need to poke the other end of the plunger intro the hole to see if there is a clog in the tube....

We've never used anything but what we had in the stick house as far as TP goes. Our present DSDP is a direct drop into the tank.
I've never had a backup on any RV we've owned. We don't use a whole lot of water but I do make sure the black tank is at least ½ to ¾ full before dumping it. Been doing that since RV's had holding tanks and toilets in them. Before that it was a plastic bag hung from a cutout in a drawer under the sink

I be they have the dreaded pyramid on the bottom of the tank.

Good luck with a suitable solution.

No white rats and maybe some fiber.

I would try the Happy Camper Extreme, then if it works continue to use the regular Happy Camper.

Does your MH have the black tank flusher? If not I would recommend you install one ASAP!

Good luck, happy trails, and God bless!

We have that same problem occasionally. I'm still uncertain as to the primary cause but I believe part of the problem has to do with the fact that there is a slight angle rather than a straight drop into the holding tank. I can't see the bottom of the tank though the toilet but there is a pretty good angle and the pipe isn't very long. I think a contributing factor is that the black tank isn't very deep ( I'd venture less than 8") so it'll pile up quickly and plug. I carry a short piece of garden hose in the drain bay just for the purpose of clearing it when it does occur. I initially blamed other family members for not using enough water when they flushed or using too much TP but I've had it happen when it was just me using it for a weekend. What seems to help is to always put a couple of gallons of water in the black tank after draining and fill the toilet bowl with as much water as possible before flushing, (depending on the circumstances, a second full flush may even be in order). As others have mentioned, only dump the black tank when it's at least 2/3rds or more full, but I imagine that you already knew that. Hope you solve your problem.

I helped a friend with the dreaded pyramid on the bottom of his tank, his black tank valve was leaking so it left the solids.

Black tank must be closed until you dump, I have know people that leave them open, not good. Another possibility, could be a piece of construction material or scrub brush in it .?? Good Luck ,Let us know how it turns out .

Well, until the OP comes back with more info, I believe we're stuck too.

susieb58 · 10-29-2014, 07:25 AM

Husband has decided to have it looked at. Thank you all for the info!

I just purchased a 90 degree clear angle to hook up to the Blk water drain with a hook up on the top for a garden hose. $25.00 @ CW You turn it on and it shoots a stream back into the Blk tank and with in a few minutes you will see what was the problem

Ahhh.. I believe that's a 45 degree elbow. I have a straight one on mine, but I also have a 45 in my spare container with all the other different attachments I've accumulated over the years. The clear adapter is very handy to have....wouldn't be without one.
