Craftsman quality extremely satisfied!
I replaced my old Extrol tank that lasted over ten years. I thought I would upgrade to the ExtrolPro tank.

Perfect for my needs
I called Extrol. They recommended this EX-30 Pro for my boiler system that holds approximately 50 gallons of water with a 150,000 btu wood boiler. I have installed and it works perfectly.

Replaced an expansion tank that expanded!
Replaced a previous tank that expanded - side wall rusted out and expanded by blowing out a hole. Hoping that this tank lasts much longer!
