Description
The Kockney Koi Demountable Union should be used in conjunction with 1.5″ Solvent Weld PVC Pipework. Demountable Unions are ideal for positioning before and after Pumps, UVC’s and Filters to allow them to be easily removed for maintenance or replacement. Simply unscrew the fittings and the pipe can be separated. Comes supplied with the demountable coupling body, retaining nut, socket and sealing “O” ring.
Solvent PVC pipework (black waste) is similar to the downpipes from the guttering outside your home and is usually a cheaper alternative to the more heavy duty pressure pipe.
Apply solvent cement (non toxic) to both surfaces to be joined. Insert the pipe into the fitting to its full depth. Allow a few minutes for the cement to set before handling/ moving. Solvent weld pipe and fittings are strong and durable and provide a permanent fitting when secured with Solvent Cement.
