Drainage issue

[richie9648]

Hi

 

Hope this is the right place for this 

 

Got an issue with the waste pipe from shower and bath in that the waste water (not poo or pee) will travel down the pipe and just overflow where it is positioned on the gulley and thus floods the garden.  The drain is running fine by the way and not blocked. 
 

video attached which probably explains a a lot better. But been getting different advice from the trades - one guy quoted £300 to sort whereas another just said get a 45d bend and you will be done 

 

any suggestions ?

As an immediate and temporary solution you could modify the hopper below to stop the overspill.

 

You'll probably need to dig a bit of a hole and need a straight coupling to connect the hopper to the existing pipe.

 

@Nickfromwales may pitch up with a better idea so will defer if so.

The gully trap is either blocked or is not connected to the drainage system.

 

This looks like the pipe is connected to gully trap serving a rainwater downpipe. You really should be separating the foul and storm systems. Connect the foul drainage pipe to a new gully trap and connec5 the gully trap to t(e foul drainage system.

Good point of note.

 

If you have a house say built circa the 1950's then please check that you don't have a separate rainwater and foul drain system.. your plumber should know this. If you put your sink waste into the rain water drain this goes straight to the watercourse and kills wildlife.
