If you live someplace like Phoenix, you also need to consider plumbing issues that relate to hot weather or you'll be calling a local Phoenix plumber. “More outdoor fun means more dirty clothes. Be sure to check your washing machine hoses for bulges, leaks, and cracks,” states the website of national company Rescue Rooter. The website also recommends being aware of condensation in your ductwork if it is humid as it may cause back up in drains. Leaks in the seams cause condensation. The company also states that sewer line back-ups are more common in the warmer months due to spring root growth and summer rainwater.
