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. Allow five minutes to set before handling and twelve hours before testing the system. It is recommended that externally installed ABS waste systems are protected against prolonged exposure to sunlight with exterior gloss paint.
