Blocked waste tank Forums

Spent this past weekend at Wharfedale CC site. Went to empty waste tank on the way out and nothing came out. Drove home thinking that it must all have leaked onto the pitch Embarassed

At home pumped more water into the sinks and looked underneath - nothing - eventually "waste full" lamp came on.

Our last van, a Swift, had a screw off cover under the waste tank to clean it out, unfortunately this one does not Crying or Very sad

Looks like I will be spending this weekend under the van dismantling pipes and getting covered in waste water.

Still, better than having an RV with blocked black tank Very Happy

Hi

Seems a bit strange to get blocked though.

As a precaution, I leave the tank half full and add a couple of litres of bleach now and again. I then go on my travels and after a few hours on the motorway, the tank is clean.

When you open the drain valve, do you get anything, even a drip, drip, drip or nothing? My Compass was once blocked, but luckily the block was in the waste pipe, which once disconnected, cured the issue.

Hi Russell

Yes there is just a very slight drip. My waste pipe goes through 2 right angle bends, one vertical and one horizontal so reckon the problem is gunge in one of them.

Hi Trevor, A;; you need to do is open the tap & reverse flush it with a hosepipe. ALWAYS works, Steve

Just be careful, if the waste tank is full it could well end up all over the shower.

Once you get it empty, add a few litres of cheap coke to the tank and go for a lengthy drive .... guaranteed to strip every last bit of grease, gunk and gunge from the innards! Shocked

Back flow it. Guaranteed to do the stuff. Of course one could blow up it Shocked

Thanks all, will try back flushing before I fetch the toolkit. Will put the plug + weight over the shower drain first Laughing
