blockage - best remedy products?

[separation]

I suspect my bath has a blockage. If I fill up my bathroom sink and let the water go, it will run as fast as normal but then some more or less clean water emerges from my bath plug hole.

I have checked the obvious pipes for blockage but did not find anything.

What miracle product shall I use? and how do I know if the blockage if between the sink and the bath or after the bath?

Many thanks.

If this is recent then it could be partially blocked after the bath and basin but if it has always been like it then it's bad plumbing. The bath and basin should not be connected directly together unless they both go into a large bore pipe where both can drain at once and backup cannot normally occur.

It looks to me, like you have a partial blockage in your bath waste-pipe, probably filtering through a mat of hair. I had the same problem myself a while back and it eventually cleared its self.

Plenty of bleach based miricle products on the market, make sure its safe for septic tanks if you have one..

Or use a rubber plunger on the end of a wooden stick. These work by forcing water under pressure along the pipe which puts pressure on the blockage.

builders mate had the right idea, but there is a new type of plunger that is like a big bicycle pump. it draws a quantity of water up then blasts it down the pipe under greater pressure.(make sure you block the over flows on bath and sink tho' ) also if the bathroom pipes exit to a pipe on the wall outside check thats not blocked with hair etc after youv'e unblocked the pipes inside.
