Additional pipe installation techniques that would help minimize pipe freezing’s that I won’t expand too much in order to keep this post reasonably short would be: • The running of pipes through beams (above heated spaces below) & then projecting pipes out into cantilevers minimizing the amount of piping in soffit areas. • The running of water mains up from below grade into a heated space with no fittings or valves in unheated areas. The valves or fittings become choke points for the water & provide greater metal surface areas to create a higher likelihood of freezing. • Not using Pex fitting (especially elbow fittings) in unheated spaces. Pex piping is plastic piping & the fittings are metal. The metal acts as a heat sink and amplifies the freezing process at these water choke points. Pex, being plastic cheap nike air max shoes , is flexible and can be gradually bent and run in such a manner as to enable it to be installed without fitting to make a 90 degrees turn (elbows). • The running of pipes to a vanity on an outside wall that come up from the floor into the bottom of the vanity rather than into the exterior wall would be another recommended practice.
