I have a Wema S3H sender in a black water (poo) tank. It is stuck. Has anyone experience of using an enzyme product such as Thetford Tank Blaster to clear it? Any recommendations?
I would, however its under the deck so I can only get it half out. To do as you say The whole tank would have to be moved.n only get it half outWear a face mask and just take it out and clean it. It's not as bad as you might think. Just make sure the tank is empty(ish) first.
And wear a face mask and goggles.
