The electric pump on our lavac toilet has been quietly pumping away but nothing has been moved from the bowl. When I switch to the holding tank the pump sucks away quite merrily and everything works. So I have a blockage between the diverter valve and the stop cock. The manual holding tank suction pump that connects to the stop cock through a Y connector is obviously pumping against a back pressure. My problem is that I'm afraid I have pressurised this section of pipe work so that when I start on the lovely task of clearing the blockage there is going to be a sudden release of pressure with the accompanying spraying of nasty matter all around.
Any suggestions on best way to proceed gratefully received
