First time here so excuse the terminology! I have a blocked soil pipe (which runs inside the garage) which is oozing at the the top joint where the new-ish plastic pipe meets the old iron pipe. Vertical length about 3 foot. Joining this is a pipe going to the downstairs bog. I've sussed that the blockage is possibly in this vertical plastic length of pipe as when I flush the downstairs bog a few times there's no oozing at the top but when I flush the upstairs bog just once there is. First up, am I on the right track? Second, if so, is there an easy fix (pressure hose from the upstairs bog?) or is this a remove/repair job? It's unlikely I can get any PPE at the moment to do this but we can always use downstairs if needs be. Third, am I simply way off the mark? Any help would be much appreciated. PS tried to upload a photo but file size too big it seems (2.7mb). Edit, pic below now. Cheers
Is the upstairs loo flushing normally ,no gurgling sounds ,or water level in the pan unusually low or high after flushing ?
Get as many buckets of water that you can in the upstairs bathroom, flush the toilet and pour in the buckets as fast as you can and keep flushing the toilet. Could also fill the bath with water so you can replenish the buckets quickly. Theory is that as the head of water builds up in the soil pipe it might blast away whatever the blockage is, worth a try otherwise its a case of cutting the soil pipe and then making good.
Ok so I tried the bucket of water trick (at least a bath full) and the water appeared to be running freely down the pipe after about half a bath full, at which point my wife took on bucket duties and I went for a look- there appeared to no issue with water level, gurgling, etc. If as terrymac mentioned its a bad seal would this be as simple as some lashings of sealant (don't laugh) at the join?
Look closely at the plastic fitting ,where the cast iron meets it . There is ,at the top of the plastic, a ring ( about 15 mm deep). It can be levered off. That plastic ring holds a rubber seal inside. It's that seal which has to make a watertight seal against the cast iron. And it isn't !! I would unclip the plastic and investigate. If need be ,pack it with plumbers mait putty and clip it back on.
Great, I managed to pry it off so will give that a crack when I can get my hands on some putty. Thanks
Thanks. I may be wrong ,but it appears that the cast does not fit into the plastic pipe ,but just rests on the slightly wider section that holds the seal. Does it ??
Pics as promised. Noticed it's a right bugger to get it line up well enough to go back to its flush position the full way round. Maybe there's a back to it. B&Q shut on the way home from work so no putty for now.
You'd probably be better off replacing the vertical section of plastic with a longer bit without the collar and connecting to the cast iron with a rubber collar and jubilee clips (sorry I've forgotten the trade name).
