Can I get full drain fittings installed in my tank?
Yes, you can. We have some special bolted style fittings that will allow full drainage in cone tanks. We can also weld fittings into tanks, that are flush on the inside, allowing for full drainage. We can also weld fittings into the sides of tanks, very low, for almost complete drainage. Please be sure to specify if you need full drainage when ordering.
