Power Plumbing continues to try and help future customers as well as existing customers. In cold weather, many homes of new construction as well as bad plumbing on install of water supplies hot and cold in exterior walls rather then up through floor for toilets on outside wall and lavatory sink.
Turn the heat to 65 degrees and leave cabinet doors open where water lines, (pipes), are present. Run a very light stream of water through pipes, this makes it very hard for water to freeze due to movement. Make sure your drain can handle the water flow before leaving fixtures run. Toilets are harder to keep water running through them, we recommend on lifting the tank flapper up slightly for water to run through toilet, this can be done by removing tank lid and flushing toilet then keep tank flapper from sealing the tank so water will continue to flow on toilets, make sure your fixture can handle the water flow. In certain conditions it is wise to call a licensed plumber for problems with freezing lines.
