I'm sorry, but I now consider Peter Parry's views on the Saniflo to be a masterpiece of understatement.
He omitted to mention that getting the "easy clip on top" off a Saniflo is a labour to be compared only with Hercules' cleaning of the Augean stables. I can't for the life of me recall which aspect of moving a Saniflo from the downstairs cloakroom to a third floor bedroom was the most tear inducing. I have had to manhandle the putrid, stinking object out of the cloakroom and into the garden where I managed to decant the contents directly into the septic tank, well sort of, becuase the concertina rubber flange grabs on to any passing poo as if it were atrue anal retentive. Then I read the booklet which promised that the lid would simply clip off. Two hours later my wife appeared to find a man rolling around the garden with a Saniflo clenched between his knees battering at the lid shouting "bastard" at intervals. All fingernails broken, shit and paper paté sticking to the most likely and unlikely places. Eventually it came free and the entire inside was then cleaned until it shone.
Then came putting the lid back on. This is jjust like removing it only harder. I ended up pogoing up and down on the Saniflo weeping with frustration, too tired to do anything else. It's almost impossible to push the lid down firmly enough to latch because the cheap plastic body flexes whenever one attempts to push the clips into place.
Then refitting it. Which genius decided to put the inlet for the basin in exactly the same location as the overflow from a close-couple cistern? And where the hell does anyone get 22mm to 32mm adaptors to allow the 22mm outlet of the Saniflow to be connected to a standard soil stack?
I despair.
After much searching I eventually found the old 22 to 32 adaptor that the builder who did the work on the cloakroom had removed, and thrown into a nettle patch behind the garden wall. Thank heaven that (a) he was lazy and (b) my neighbour had spotted him throwing stuff over the wall.
Saniflo finally fitted. I expect it to break down next week, or even tonight.
