Just babbling a bit...
Well we have the plumber here this morning - after fighting a slow drain for the last two weeks, I threw in the towel and told my wife Cindy, "I don't know what the heck the problem is? Let's call our plumber..."
One day our drains are just fine, and the next day or two it's a dice roll whether or not we get some backup and or gurgle.
As I understand it, my neighbor down the hill (a few houses from me) she has also been having drain problems - and they even scoped her main line and found nothing???
I'd like to blame it on roots, (we have been having a lot of "Spring" time warm weather with no moister, but the nearest growing things to my main line is the neighbors' hedges 20 feet away... The roots would have to go basically - up hill to search for water, so I guess that's a possibility?
So,,, we'll spend the money today and find out what our plumber finds out???
My plumber just told me (and I heard the gurgle) he found some blockage at 83 feet (he'll be at the main city drain in about 24 more feet...
