Blocked Drain - help please

I'm pretty sure that acid into the pipework isn't a great idea. The fumes coming off it if/when it reacts with stuf in the pipes can cause damage to the communal sewer that could be recharged to yourself if traced back.Maybe I am wrong but in my 7 years water/sewage company experience we would never recommend that and I am pretty sure that it can damage the pipework depending on the material it is made from.

Someone like Lanes for drains would come out and do it, they (when I last checked) wouldn't charge more than £150 but would also have a push camera that they could use to see what the actual problem is that is causing it.

Also - if you get someone out make sure you warn them well in advance that the acid is down there

I would never use it inside the house. It can damage pipes and joins. But used in an outside drain leading to the sewer in small quantities can't damage a brick and concrete drain & sewer system. it can't dissolve stone. You could get a pressure build up but as long as one end is open it won't build up pressure. It's disgusting stuff, don't breathe it in it let it have any contact with skin.
