Client called us out due to some water hammer noises in the walls when washing machine was running. First thing we checked was the water pressure and it was perfect at 60 psi. Water heater is brand new and thermal expansion tank is good. With it being just at the laundry indicates to me there is no major issue, and best course of action would be replace the laundry box and shutoffs with new that have hammer arrestors, which would stop that nuisance noise. Client decided if it was not a major issue, they would not worry about it. Left estimate to do that work if client decides to move forward in the future. Waived service fee for good repeat customer.
