WebbExcessive hot or cold temperatures will lead to discoloration, cracking, or hardness - as well the build up of static electricity if hose wire has not been ground properly. 4) Surging or excessive working pressure - Usually a large burst with torn reinforcement, typically along the outside of a bend. Webb23 juni 2012 · Bending pipe also was a big plus is water flow increasing the pressure due there being no 90 or 45 degree fittings to obstruct flow. And pools consist of hundreds of 90's and 45's. The same goes for ABS pipe (drain pipe) for fixing badly cut or pipe which just can't match up to the angle of the cuts.
