Blog 154 Replacing the Waste Water Tap

Hopefully a useful and helpful Hint & Tip Sadly whilst we were away on our ill fated Scotland trip , until the engine gave up (see blog 152, now rather costly repaired but we would never give up on our trusty Wendy House) the waste water tap would not drain away properly. Overall it seemed to be a trip of multi repairs ;) beside the roof not staying open, the fire came off the wall after a heavy bumpy road and the sat nav broke free from its mouting on the dashboard. As they say these things are sent to try us.

Anyhow getting the old tap out wasn't too bad. The Motorhome company had put this one on in the past and it has always had too narrow a channel. It seems after all these years the inner flow channel had been clogged with gunge etc.

All you have to do was remove the outer edge sealant, rotate the tap anti clockwise, it fits into a screw channel inside the waste tank. This unscrewed quite freely, when examined it was full of what looked like congealed fat, which despite pouring hot water down the sink on numerous occasions obviously hadn't worked.

Having drained off the waste water from the tank, 2 bucket loads I then used a pressure hose to completely clean out the system from both inside (both sinks) and underneath directly into the tank. This worked a treat. I completed the cleansing operation finally with boiling water in through the sink. Happy all ok and clean I attached the new wider channel tap (£4 via ebay - I note that Don Amotts charged me £80 last time the tap was replaced, what a rip off!) by rotation, screwing into the internal thread, making sure it was seated in the grooves properly. When attached I then applied 3 succesive securing layers around the outer edge of the tap to ensure no leakage. Each layer 24 hours apart to ensure true bonding. 1st Gorilla glue (a plastics super glue). Then no more nails for hardness when rotating the tap and finally white silicone. As they say the "jobs a good un". I'm happy, much cheaper, I learnt something and hopefully good drainage for years to come, fingers crossed Thanks for looking.
