Best Electrical Check in Milwaukee WI

Had 2 tankless water heaters installed approximately in 2021. Pressure relief valve failed on one of them. Valve was under warranty. Phoned and emailed repeatedly. Finally after 2 plus weeks they got back to us. The problem was resolved. Now the relief valve on the other is failing. Emailed them on January 2nd and received no reply to this date. Please contact me so I can get this situation resolved. Installation of water heaters were done professionally and I was very satisfied. But getting in contact with company could use some improvement.
