Upgrading the Bathroom Waste Pipes.

I was not sure how to tackle this. I used domestic style 32mm grey waste pipe, it's greater bore would improve the flow. Push fit seemed the easier option, apart from those decisions it was make it up as I went along!

The new pipes will be shorter and use a waste container to the side of the caravan.

Before starting work, the caravan was checked to make sure it was level.

Bathroom location
The bathroom waste pipes (shower and sink) emerge behind the wheel and head to the rear.

Location of pipes
 Both waste pipes terminate at the rear of the caravan.

Brittle pipework
The pipes are brittle, temporary repair of duct tape did not work. Shower outlet furthest away.

More detail
To remove the old pipe unscrewed the clips, will reuse the screws for the new clips.

Shower outlet
The shower outlet, the shower tray is just above.

Master plan
The overview; shower outlet on the left, sink outlet next right, this will have a standpipe from the sink, then drain to the right.

Sink outlet
The sink outlet; tried a hole cutting bit, but could not centre it, marked around a fitting ready for drilling a series of holes.

Drilling holes
The holes are close together, only drilled through the bottom ply.

Stanley knife
Used a sharp blade to join up the holes, then took out some of the styrofoam to accommodate the fitting.

Trying the fit
Trial fit (notice I have put the sink fitting on the wrong way round!) To get a fall in the pipework....

Packing pieces
used some pressure treated timber 18mm thick, cut one piece to 8mm thick, used contsruction adhesive to attach to the floor....

Glued and screwed
then a couple of screws to hold in place while the glue sets.

Shower extension
Back to the shower, to make sure there is no splash back a short piece of the original pipe (a sound piece from inside the caravan) was attached to the outlet.

Securing the pipe
The angle piece fits over it, pipe clips secured to the timber with original screws, drilled pilot holes first.

Two pipe cilps should be enough. Notice the "fall" on the pipe created with the timber, thinner piece to the left.

Original pipework
Now for the inside, this shows before the standpipe was fitted,hot and cold supply pipes tie wrapped to the waste.

Original waste reused
To make life easier, used the original flexy waste pipe from the sink left long.

Pushed into new standpipe
It goes down the standpipe approximately 150mm.

Securing the standpipe
Then a pipe clip screwed to the wall keeps everything in place. Tie wrapped the hot and cold pipes to the standpipe.

Showing end-cap 
A better view of the end of the pipe, which, when not in use is covered with an end cap.

A closer view

Push in extension
In use an extra piece of pipe simply pushes into the end replacing the end cap and the outlet is directed into the waste container.

After using, it was decided to upgrade the standpipe to a trap, to stop any smells from entering the bathroom.

Standpipe to trap upgrade 
It was a simple matter of cutting the original standpipe down to fit the trap. Used the same bracket to secure the trap to the wall. Then the flexible pipe from the sink was cut shorter and pushed in the top of the new standpipe above the trap.

Jubilee clip on sink waste 
Put a jubilee clip on the tube attached to sink as it "fell off !!" when we were filling the system on a trip away. Putting this on it will make sure it will not come adrift again. 

Shelf back in place 
The shelf had to be altered slightly to fit around the nut on top of the trap, as it was bigger. Used a coping saw to cut out. Now that should be the bathroom finished.
