For this customer they have reliable hvac, plumbing and electrical came out to snake the tub drain. However the problem is the the other tech took off the drain to run a hand snake on the tub. And he didn’t take off the overflow plate. When he was done he went back with caulking rather than silicone or plumbers putty. What I recommended for the repair is we replace the overflow cover plate and the drain with new plumbers putty. The customer is wanting to see if the other company will warranty the work as it is their fault that water is leaking below to the other unit. At this time no repairs will be made. Wasn’t able to check water pressure. No hose Bibb or individual shut off valves. Water heater is from 2011 recommend to replace
