Customer has 4 to 5 toilets that need to be partially rebuilt, leaking pot filler, gas dryer connected to the gas line that is existing, and both tanklesses need to be descaled but there are no bypasses to provide such a service. Provided a maintenance plan for the units we discovered, excluded the tanklesses because of the service issue. Could not contact the customer to explain the tankless issues but provided estimates to his email and will be waiting for a response.
