The drain at the base of the main downpipe from my upstairs bathroom is
failing to clear quickly resulting in a regurgitation of bath waste onto my
patio. Can anyone recommend a first aid fix? Something I can pour down?
Thanks in advance
I have found that the only thing that works is caustic soda solution. Pour
a couple of litres down the drain and leave overnight without letting any
waste water go down that drain to avoid diluting the caustic soda and to
give it chance to dissolve the gunge. Then run some hot water down the drain
and apply alternating suction/pressure on the bath plug hole using a drain
unblocking pump or sink plunger, whilst covering the overflow to avoid
loosing suction/pressure. You might have to repeat this process several
times if you have got a really bad blockage. If you go ahead with this, be
very careful using caustic soda as it is very nasty stuff if it comes into
contact with skin or eyes, or if you inhale the fumes.
Certainly one of the first things I'd think about. Any toddlers in the
house? They are prone to flushing all sorts down toilets. Many
menstruating females? Santitary products are a number one cause of
As someone has said - caustic soda solution. I'd echo the safety warning.
