Contributors to this topic have encountered a problem similar to what I am experiencing. Appears there is a temporary resolution using tape, silicone, and clamps. All good ideas that work and postpone any emergency until I can get replacement parts.
I need help finding a source for the repair parts. The manual included with the rig doesn't offer an exploded view. Nothing labeling or describing parts. Thetford's online presence is equally unhelpful. Appears the entire assenbly is the only item offered. Ordering parts is made difficult by the complete absence of appropriate nomenclature.
My pump works. Nothing wrong with function. However, the case has a hairline crack. Opening the valves causes a very small leak. Looking at the assembly, it appears the midsection containing the discharge hose connection is replaceable. Getting frustrated by the lack of results in that search.
