Hydronics Systems recently purchased a 3000-gallon new tank from Custom Plastic Fabrications. The Tulsa County Library’s new building project involves the Hot & Cold Water polypropylene sump. The sump tank’s contribution to the project is as part of the HVAC system, and it should be very useful. This polypropylene tank, like all of our products, resists rust and corrosion. This sump tank has a plastic window in addition to the standard advantages of using CPF’s plastic tanks and truck bodies. The built-in viewing section makes it easy to keep track of the water levels, making sump tank management a breeze.
