Frequently Asked Questions

When you have questions, we have answers. Here are answers to concerns our customers mention most often.


Pay attention to slow drains and low water pressure. Many systems will make gurgling or banging sounds. You might also notice foul odors or discolored water.

If repeated repairs on the same lines haven’t yielded long-term results, consider replacement. Galvanized steel lines typically last 20 to 50 years, depending on the specific water issues in your area. Copper often lasts 70 years, and modern PEX usually lasts 50 years.

Replacement is the choice for many smaller fixtures, such as faucets and showerheads. Repair is usually possible with toilets, garbage disposals, and ice makers. However, we always inspect a system before offering a recommendation.
