HELP - Toilet Isolation Valve

Oh boy - this is bad! We just lost water pressure - come to find out, the supply hose to the Macerator Toilet broke!!! We cut off the water pump, but are trying to find a water isolation valve to that toilet. The only isolation we've found is under the sink, but its a manifold that shuts off the entire bathroom (shower, sink toilet and washer). That works for the immediate concern, but leaves us out without the ability to use the shower. Does anyone know if there is a seperate isolation valve for the supply water to the toilet only? Also, has anyone had a similar experience with their back bathroom Macerator Toilet?

As far as I know, the only shutoff is under the sink....unfortunately Tiffin did not think that each fixture needed its own shutoff....where did the line break? Above the floor where you can work on it? If that is where, that hose can be bought in any hardware or big box store....

Yes, the hose broke at the fitting just upstream o the toilet inlet. Talked to Dometic and they are going to cover as a warranty item. Just no use of the back bathroom until. Now would be the time to add an isolation valve.

After having a toilet valve fail on a previous coach, one of the first things that I did to my last two coaches was to add a shutoff valve for the toilet.

Probably wouldn't hurt to have them on all fixtures, but sinks and showers are much less prone to failure.
