My rental house in Las Vegas has had very frequent plumbing problems lately, yesterday Roto-rooters went out and performed a camera diagnostic, and found the old metal pipe was collapsed about 6 inches in, which was causing the water overflow. They want to re-do the plumbing in the bathroom to the toilet which he said led to the main drain. My question is how much should something like this cost, and also, should I ask to get the other bathroom upgraded to newer style plumbing as well, to avoid this in the future? Roto Rooter already charged me $500 just for the diagnostic, and I think that may be a little on the high side. Thanks
