UPDATE: You can't give away a used garage door opener. They are so cheap new, no one wants a used one. And because of liability concerns (older ones have fewer safety sensors) even charities like "home again" won't take them!
UPDATE: After more camera work, we determined that the real problem wasn't our sewer line, which was replaced (with PVC) about 10 years ago, but where it met the municipal system -which had clay pipe. Tree roots were tapping into the joints at the clay pipe. I call the sewer authority and they claim they will come look at it, and possibly cover the repair. So maybe I dodged a bullet here. We'll see!
UPDATE: The sewer authority came and inspected the sewer pipe, which was made easy by the fact I spend a couple hundred having an access port put in. If you put in a sewer line, make plenty of access ports for inspection and roto-rooting! Anyway, they agreed the old clay pipe was in bad shape, but if they replaced it everyone on the block would want a new one as well. So the guy told me that if it ever has a root problem again, to call him and he will "send the guys out" to roto-root it for free. Sounds like a workable solution for now.
All of the island plumbing was installed in the 1960's and we had a water main break the other day which was pretty serious. I hope this is not sign of things to come - like with our condo! Pipes laid underground do wear out over time. Just because you don't see them doesn't mean they are not there!
