Use with ABS fittings. A lightweight yet strong and cost-effective option. Fix pipe clips at max 1.2m centres vertical and max 0.5m centres horizontal for 32mm and 40mm, 0.6m centres for 50mm. No expansion gap required on the solvent weld overflow system. Apply solvent cement evenly to both surfaces of joint, insert pipe fully into the socket depth and remove surplus cement with a cloth.
