Upon arrival customer has a tankless water heater that she would like an estimate for a recirculating pump. Customer has 5 year old tankless that has never been flushed and does not have isolation valves. She does not want a recirculating pump with a timer she would like the one with a push button. I gave an option for the taco genie with a button. I also explained the importance of flushing the water heater once a year. Customer always gets three bids and will contact us. I went over our membership program and emailed estimates to customer.
