We had a horrendous problem - someone blocked the toilet with a nappy - raw sewage was pumping out of a drain into the street. It was the last day before business closure at Christmas time and a stinking hot day, so you can imagine the stench and mess! We called a few plumbers and they had broken up for the holidays, but then we called Safe Seal. Their young chap turned up within an hour and set about clearing the drain. Much more complicated with the nappy lodged deep in the pipes, so he arranged for a pressure jet to clear the drain. He was efficient, pleasant and an asset to the company - now our new plumbers!
