Hi, we have recently bought our 2nd caravan an Elddis Elite 550 and took it away for a weekend (Pre Lockdown). Day 1 the sinks drained perfectly. The next morning the bathroom sink was filled with dirty brown water. We emptied it manually and ran the kitchen tap which made the bathroom sink fill up again. We were sited on hardstanding and were perfectly level. Any tips please?

Hi Duncan
By the look of things the drainage pipework is blocked .
Plug the washroom sink and put warm water in the kitchen sink
Use a small sink plunger or if you don't have one a plastic bag over the flat palm of your hand to try to clear the blockage via the kitchen sink.
Check the drain outlets for obvious blockages.

Has the OP tried draining water with the outlet pipe (outside) disconnected? I have seen some newcomers put the end of the outlet pipe under water in the Wastemaster (or whatever) to prevent back-smells and get an air lock.
Otherwise EUSOL (Edinburgh University Solution of Lime) or Milton will clear any blockage and sterilise the piping in the process.

Try blocking the two outlets with wine corks then pore a standard sink unblocker down both plug holes leave over night, in the morning remove the corks and run plenty of hot not warm water down both sinks , your kitchen sink may have fat / cooking oil in the pipe thats why hot water is better, should solve your problem.
Thanks Parksy. Our van is in storage at the moment (we live on a busy main road/no drive) but the moment we can we will want to use the caravan and get away for a few days. Hope you are well, Stay safe.
Best wishes, Duncan
You might need a couple of winds of insulating tape around your corks so that the outlets can be blocked. If you are using any kitchen unblocker please be careful not to splash yourself when you remove the corks, and please collect the outflow in a suitable container so that it can be disposed of and not just soak into the ground. For a less caustic approach you could try bicarb of soda with hot water and the corks method. Usually the two sinks converge to one outlet and the shower to the other, so keep an eye on both sinks as you run the tap in one while corked. Also make sure that the waste container is not overfilled or you might get a backwash to the shower tray being the lowest plughole.
In future worth a good flush though at the end of your season to eradicate smells and eliminate blockages - also as the waste is corrugated plastic be wary of what goes down the sink in the first place - for example I am careful to empty coffee grounds to the on-site waste rather than the possibility of them accumulating in the pipes.

Each time we leave a site we pour quite hot water down the sinks as an aid to keeping them clean. If you use bicarbonate of soda sprinkle it around the plug hole until you have a small mound. Pour hot water on it to dissolve the mound then leave for an hour or so. Flush with a good quant of hot water.
