Custom Plumbing today installed Hammer Arrestors, upstairs, on the water lines that will feed the washing machine and, downstairs, at the water line to the back of the refrigerator.
Above, red PEX for hot, blue for cold, with shutoff valves in case of emergency, in the laundry/utility room.
Custom Plumbing is also wrapping each water line with insulating foam. Ron Dahlke explains that PEX is designed to keep hot water hot — and it will, but the insulating foam extends the longevity to about 45 minutes. Which means we won’t have to waste water waiting for hot to slosh through the faucet. But even the cold water lines get insulation — and the hookup for the water line to the refrigerator also gets its own hammer arrestor.
