No complaints. Wish there was some reference of disinfection. Is it ready for use or does it need to be disinfected prior to use. Also, we not include the wall support.

I ordered this 4.5 Gallon Thermal Expansion Tank for a water heater replacement project.Several features attracted me to this product.First and foremost, the tank is made of 16-gauge steel, which makes it very durable.Second, the diaphragm materials (100% butyl rubber, lined with polypropylene) complement the tank's durability.Third, the entire product is lead-free.Finally, I also appreciate the 304 Grade Stainless Steel ¾" connection.My experience with this Thermal Expansion Tank has been highly favorable, and I recommend it without reservations.Note: I prefer the larger tank because it has a greater capacity to absorb water expansion, which occurs as the water temperature increases inside the water heater.

This tank was super easy to install and has been working well ever since. I did not notice any quality related issues prior to installation. The tank was well made and functions well.

The 4.5 Gallon Thermal Expansion Tank is a great addition to any hot water system. The 304-grade stainless steel construction feels durable and ensures resistance to corrosion, which is a must for long-term use. The 3/4" MNPT connection is standard, making installation straightforward and hassle-free. The butyl rubber diaphragm inside does an excellent job of preventing hot water from backflowing into the cold water lines, which helps maintain system pressure and prevents damage to plumbing fixtures.Overall, this expansion tank is well-built and reliable, perfect for homeowners or professionals looking for a quality solution. Highly recommended for those looking to improve their water heating system's safety and efficiency.

This thermal expansion tank was an essential component for my hydronic floor heating project. I'm using a heat pump water heater to warm the water, and the tank effectively compensates for the liquid expansion that occurs when the system is operational.This product is the perfect size, and I used wall clamps to securely mount it to the wall. The stainless steel MIP connection indicates excellent build quality. It's pre-pressurized to 40 PSI, so it's ready for immediate use.

Replaced the water heater in an old house and by code had to add in an expansion tank. This was a simply addition and this tank seems to be well made. I was am happy with the tank and for the price it meets my needs.

Home never had one of these installed. So when I replaced my hot water heater the code changed to add one. Very easy to install and seems to be solidly built.

Works great. Difficult to find a bladder tank that will work with hot water. This one does!
