Leaking Drains Federal Way. A Federal Way business had leaking drains that were caused by tree roots. The damage from the leaking drains was spreading and the property owner could see the restoration costs quickly increase. The Federal Way business owner found a local Perma-Liner installer to fix the leaking drains with a technology called “cured-in-place-pipe”. The installer fixed the leaking drains in less than one day and came in under the cost of replacing – the Federal Way business owner was extremely happy!
