The plastic piping system from Viega Smartpress is suitable for drinking water, gas and heating installations. This new line has been optimized to minimize the pressure loss at floor installations and riser and distribution pipes. Partly thanks to the fittings without O-rings, the pressure loss is limited to a minimum. As a result, the chance of pollution, for example due to a damaged O-ring, is a thing of the past. The entire Viega Smartpress series naturally meets the legal requirements and strict requirements with regard to good drinking water quality. The advantages of Viega Smartpress: - One system for drinking water, heating and gas installations; - Time-consuming calibration is eliminated; - All Viega Smartpress fittings in the sizes 16 up to 63 mm are equipped without O-ring; - Always a good connection, also for radiators; - Inadvertently unpressed fittings stand out thanks to the SC-Contur.
