For some time now I have been having trouble with my services. My TECMA macerator keeps getting the pipe blocked. To cure this I attach my p/o pump to the feed to the tank and pump the blockage out. Today whilst trying to perform this trick, without the aid of a safety bucket, as the macerator whirred and I pumped the handle the pipe came off and the bedroom was sprayed with doo doo. I love boating!
