Existing emergency water shutoff controls serving hot and cold water to washing machine were frozen, not allowing for water to be turned off at appliance, allowing for the exchange of appliances. Zing Plumbing opened drywall below laundry control box, renovated hot and cold water delivery pipes with new 1/4 turn water shutoff controls. Made necessary plumbing connections tested for function and leaks. Reset drywall that was removed for access. After the repair was completed, we rejuvenated drywall to original condition, matching texture, and the homeowners decided to paint themselves.
