Slow drainageAsk a Plumber
When having a shower or doing laundry water backs up into bathtub & sinks gurgle & we have to wait for about 1 hour before we can flush toilet.
If we are not doing any of the above the toilet flushes just fine & the sinks drain good
Please advise with what you think I should do for a fix
I am on fixed income but if I have to I will get professional help for repairs
Thank-you in advance for your help
