I discovered there's a leak in the water pipe that runs under my backyard. The plumber said I need to dig it all up and redo it, but that's going to be really expensive. Is there a cheaper technique to fix it without having to pull up the entire pipe?
Actually, this "without digging" thing has its risks - most of the less invasive techniques work fine for small holes, but if the pipe is corroded or has big cracks, you end up spending money on a patch that won't last. There are options like relining (basically a new tube inside the old one) or special sealants injected through the piping, but those cost good money too and need specific equipment - it's worth getting quotes to see if it really comes out cheaper than digging up and replacing. The best move is actually to call another plumber for a second opinion, because sometimes the leak is pretty localized and they can just open up one section of the yard instead of the whole stretch.
