We use drain machines with springs on major blockages in sewer and storm water drains. Rod plungers where our drain machines prohibit us from reaching. We cannot see where your drains are, blocked over the phone. So it is easier for us to come out to your property at our expense, do an inspection, and then give the client a quote. If the client is happy with the verbal quotation, then unblocking begins. There are times that a plumber will get half way down the drain line with springs. Without getting through the blockage. This means that the drain has collapsed. Part of the drain will then have to get replaced. Roots can cause major problems for drainage pipes. Roots start off as thin as hair and make their way through any small pipe. Fitting, or crack in the pipe, thriving on water and sewer passing through pipelines. Making the roots stronger and thicker. Causing blockages and, in most cases, causing damage to the pipe line. No matter how many times you unblock your sewer lines. Or any underground pipes, once roots find a way into the pipe, there will always be problems. Spending money three times a year on unblocking pipe lines. Ends up costing you more than to replace part of the line.
