Fowl water started seeping up through my conservatory floor this weekend. The conservatory is built along the rear elevation of my house and therefore one side is what used to be the outside wall of the house. On one side of this wall I have a sink in the kitchen and a sink in the utility and on the other side the conservatory. One waste disapears into the cavity between the two and the other goes down the outside wall and under the conservatory at the joint between the conservatory and utiilty. A contractor came out to resolve the problem and started by breaking up the floor! They discovered two seperate open gullies under the floor with the waste pipes draining over them. The builder had simply placed a plywood sheet over these and tiled on top! The blockage was actually found "downstream" in the main (outside the house) and has now been cleared. My question is how should the job be done properly so that I will not get fowl smells or "build back" again given that the drains cannot be re-routed outside the conservatory and that I need to end up with a new tiled or laminated floor? I will not attempt to do the work myself but I need to know what I'm talking about and what I want when the insurance assesor visits tommorow!
Sorry for the length of this post!

steve,dont worry its not the end of the world,you can get a special connection so that your 2 " waste pipe goes straight into the run,it would be like a 2" to 4" adaptor,you dont normallt need to trap these kind of connections as the trap would be inaccesable anywa y.
it is worth constructing some kind of access panel in the floor so that you can get to it in any future crisis
hope this helps

Thanks triple L.
So basically the two waste connections could just be jointed straight to the main using an adapter from 2" to 4". Makes me wonder why they didn't just do this in the first place? As regards the access panel I assume you mean like a small diameter Access Chamber which needs to break the main in between the two wastes and then I suppose the two wastes could then feed directly into this . Meaning then that via this I could rod the main or the two wastes if we had any future probs. Any ideas on the type of AC (as small as practical) which has a "lid" that could be both airtight and sunk in and integrated (tiled over/within) with the tiled or wooden floor (when replaced).
Sorry to ask for more, cheers.

just go to your local plumbers centre and they wil have catalogues showing what you need,you might need a durgot valve which can be unscrewed for rodding then farhter down a double spigot collar to take the 2 wastes,then a rest bend 90 deg. then a clay to plastic adaptor (if your existing pipe is clay) or a plastic to plastic.
TBH its a mornings work for anyone half handy
