We have a bunch of pipes running around our house and the yard as parts of a homemade sprinkler system and outdoor shower (previous owner of our house was a plumber.)
Last fall, I turned off the water to outside in November, and opened all the taps so any remaining water would drain out and dry. This has worked in previous years.
Over the winter, we had freezing days as usual. One night I left the garage door open by mistake, which burst my pipes inside the garage near the main, and I fixed them myself using Sharkbites. However, I thought that the pipes I had turned off would be fine. Now that it's spring, it turns out that we have four leaks! One of them is due to a crack in a spigot. One is a split in the outdoor shower pipe. And two of them may be underground on the way to different branches of the sprinkler system, because there is low/no pressure from those outlets, but I haven't located where the leak is.
Is it time for me to move beyond sharkbites? But first, why did it happen?
