Re: Dometi VT2500 vacum toilet
Hi Smallbore, I have one of these in my van.
First off, what caused you to notice the problem?
For example was every thing ok and then failed just after emptying the tank?
Or did it play up just after a flush?
When ever you leave these toilets idle they should always have a half cup of water in the closed off pan .
Any loss of water will be noticed and may indicate a leak in the line or at the tank.
This water not only seals the rubber seals but also softens any paper that may have been caught in the closing of the seal.
Put your foot on the pedal and look right into the bottom of the toilet and you will be looking into that part with an X under it. If you look at the picture, the effluent must either go left or right depending on the installation.
That small pipe is to the left or right may be blocked with paper. So check that out first. the toilet may make a noise while you have the pedal down but it won't worry you get a torch and have a look there first.
If you see paper get a 2 03 mm length of wire and start to loosen to carefully. If the bowl has water in it get a small cup ; a lid off a spray can is ok and remove all the water so as to see the bottom. One assumes you will have on a pair of gloves.....
If you said it was running continuously it would probably be a leak at the tank.
Note! Never use neat olive oil on the rubber O ring or any seal. Rather use a inert teflon grease.
The top arrow is the direction of flow. the bottom X is where the effluent passes to the pipe and then to the tank. The X indicates the left hand outlet but the right shows a right hand outlet . you will only have one of these part in the toilet.
