We had SMELSCER PLUMBING install two 50 gallon water heaters in 2018, one upstairs & one downstairs @ $750 each, with a 6 YEAR WARRANTY. Within 1 YEAR the water coming from the upstairs one smelled awful - like rotten eggs. They drained it and charged us another $200. NOW the UPSTAIRS water heater HAD COST US $950. Within 3 YEARS (of a 6 YEAR WARRANTY), the upstairs water heater QUIT WORKING. They said it had to be REPLACED (UNDER WARRANTY) & said the LABOR TO INSTALL IT would be $600, meaning the upstairs water heater NOW COST $1550. Also, even though they were installing a NEW WATER HEATER, they would only honor the 3 YEAR WARRANTY left on the FAULTY WATER HEATER. WHAT SHOULD THEY HAVE DONE? They should have gone back to the company and NEGOCIATED (on behalf of their client - US) a NEW WATER HEATER with a 6 YEAR WARRANTY, and NEGOCIATED with the company to PAY THE $600 INSTALLATION FEE. They DO NOT BACK UP THEIR CLIENTS!!! AVOID THIS COMPANY!!!
