We would like someone to check if we can build a conservatory/extension over existing drains/sewers.
water from bath & toilet upstairs backing up into kitchen sink. We have rods but unable to go round the bend. Not sure of cost so looking for quotes.
The washing machine is in the kitchen and appears to share a trap with the sink. We have had no problems draining water in the sink, but the washing machine has started leaking water back out of the vertical drain pipe. We have tried running a hose pipe down the trap but this had made no difference.
