I need to replace the flexible corrugated plastic pipe that runs from the kitchen sink drain to the grey water tank due to a leak somewhere in the line that runs through the sub-floor area. The distance from where it enters the sub-floor to the grey water tank is just over a metre. Does anyone know how I can access this area short of removing the upper floor?

I had a similar problem on the Dethleffs, push fit pipes not welded, had to take door pillar trim off one side to allow floor to lift.

My guess is, assuming that you can get to each end, is to tie a string on one end of the old one and then pull it through form the other end. Then tie the string onto the new one and pull it through.

PostScript: I was determined to repair the leaking pipe in the subfloor, but the only way was to cut a section of flooring out as shown below.

Picture above shows new flexible pipe connected to grey water tank. I managed to put the bits of flooring I had cut out back in position and screwed a strip of 3 ply over the repair and then covered it with a rug.

enough to know i shouldnt touch things i know nothing about ....
looks like an ugly job, but sometimes it just has to be to get the job done and as you've managed to salvage the cut out bits and refit them you've turned an ugly job into a bloody good job well done! how did you discover it was leaking?

Water was going down the sink but not entering the grey water tank resulting in damp lower floor. Previous owner was using 5 litre plastic bottle under sink and emptying this on each wash up.
