Customer stated that laboratory faucet up stairs was backing up and leak. Found that when we ran water in lavatory that water came out through kitchen cabinets. Do to location of leak and access recommend reliable restoration to come and remove cabinets first before any plumbing work is done. Also tested pressure to home and pressure was about 115 psi. Gave customer options on repairing pressure issue at this time. Customer didn’t want to proceed with repairs.
