Calculations are presented to determine the pressure loss in the water supply elements of the installation for washing the drainage, taking into account the used water flow rate, the inner diameter of the washing pipe and its length. Based on the calculations, it is recommended that the installation for washing the drainage UPD-120 be completed with a flushing pipe with an inner diameter of 20 mm and a length of 300 m.
