Upon arrival, customer explained that they received an inflated water bill likely due to a leak in the water supply system. After a thorough inspection, we determined that the leak was coming from 2 toilets - the main level powder room and upstairs guest bathroom - due to age and condition of poor quality materials used during initial installation. With customer’s approval, we replaced the fill valve and flapper in both toilets. During our inspection, we also discovered an improperly piped water heater as well as an improperly installed thermal expansion tank. We secured the expansion tank to the structural wall as a courtesy. A quote to properly pipe the water heater and replace toilets has been provided to the customer.
