If you noticed the following what is the necessary course of action (to do with drains)

[hobbgoblin]

Dishwasher leaving residue, bit of a stink about the kitchen. Kitchen sink functioning fine.

Put washing machine on this morning, went outside to notice the drain bit where washing machine/dishwasher overflow goes into is bubbling up and overflowing everytime washing machine drains.

Which bit is probably blocked?

What do I do?

I don't need this as have a backlog of washing up and laundry due to being out in the sun all weekend and neglecting housework duties.

unblock the outside drain

run the dishwasher and washing machine on empty with vinegar to give it a good clean

God, you know I posted about a note that the local residents posted about blocked drains last week? This isn't soil stack so would not be relsated would it?

Thanks rubyslippers

If i don't have caustic soda what might be the next best thing for the drain bit?

I have poked the drain with sa stick. It didn't exactly work.

A stick won't work because it won't reach the blockage. To do it properly you should use drain rods. However these are expensive, and a hosepipe does just as good a job.

You'll probably have to do it a few times. Try wriggling it, jabbing it and blowing very hard down it.

If when you have poked it down, it seems to get stuck, this might not be the blockage, it could just be that the drain has changed direction. If you pull the hosepipe out and it doesn't have gunk on the end, its probably just a change of corner. Put it back in and try twisting it around and it will probably find its way around the corner.

If you are going to fiddle about with them, don't pour any nasty drain cleaner stuff down first.

We have a drain that always backs up because of the position of the soilpipe to the inspection chamber. That was the professional opinion of the drain cleaning company that came out.

Now we have a length of plastic white pipe (left over from bathroom re-fit) that we stash in the garden out of reach and every few months we pop that down into the poo water (awful) and wiggle it about so that the air gets in and moves the stuff along.

Agree with wiggleJiggle as well. Hosepipe and air blowing.

Yes it may have something to do with backup of soil pipes as our washing machine drain flows down a pipe into the inspection chamber filled with poo water
