Customer had a leak on 1/2 copper hot line in garage ceiling. Cut and repaired the leak on the line for search for concealed leak price. Checked house pressure just over 80 psi and installed a new 1 inch prv. Customer also needed tankless serviced. Flushed the unit. Noticed on startup it coded an error 12 message which is failure to ignite. Noted this to customer. It’s only did it initially and doesn’t pose immediate concern, but if any additional issue happen diagnostics may be necessary to repair or replace components on the gas or ignition system. Replaced leaking widespread faucet upstairs.
