The Kockney Koi Demountable Union should be used in conjunction with 40mm 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.
Solvent Weld pipe and fittings are strong and durable and will provide a permanent connection when secured with Solvent Cement.
