Help please. I recently had a rental house I own renovated. I have an old fashioned jacuzzi from the 80"s with a deck mounted faucet. When the plumbers changed the faucet they didn't turn the valve back for the water. They then sheet rocked over the valves without them on. I haven't lived there for over 30 years and don,t remember where the valves are. Tenants moved in yesterday so I don't want to make numerous holes in the way causing it to be repaired and painted. Any ideas?
