Our electric Thetford flush stopped working making sounds as if it was empty. We had done 3 weeks travelling without a problem and had been parked on site 3 days. Filling it didn't make any difference. Moving on next day and after 2 hours driving (you know how it is) toilet flushes fine. I only ever use proper pink stuff which goes in before the water in measured dose. If dirt is being introduced somehow and blocking the flow how can I clear it without hooking up and driving 80 miles? I tried a needle into the opening without any result so nothing right at the end.
Any help greatly appreciated
