We had to turn off the external stop cock tap to fix a leak; then turned it back on after we finished works. But I noticed the deep pipe where the stop cock is, is now full of water. Is this normal? Have we broken it?
The basement in our victorian house is really damp, and after some inspection we believe we have narrowed the cause down to two things:
1. Blocked airvents = this is visible and confirmed
2. A missing connector between the cast iron downpipe at the front of the house and the clay gully...
