Yes, there are many options. First of all there is the choice between galvanised steel and CPVC plastic. All our units are available in left and right handed versions but the CPVC versions are also available in two different form formats, one for riser spaces where the unit will be installed vertically and one for void spaces where the unit will be installed horizontally. The idea of these formats is to save valuable space, please download our data sheet for more information. Furthermore, our CPVC versions come with either a standard drain valve or full-sized drain valve and a pressure gauge.
