winterizing plumbing

[charles lindsey]

Bought a double wide in May that is located at the lake. I don't want to leave heat on 24/7 as it is only a weekend retreat. I have installed a drain line on the incoming water supply line and believe that I can drain all of the cold water connections through this drain. What I can't figure out is how to get the water out of the lines that are downstream of the hot water tank. The lines between the tank and the faucet are what I am concerned with. The lines must run under the floor but there is a plastic covering which I assume contains insulation. Any ideas on how to drain these lines would be appreciated.

Do not for get anti-freeze in toilets and sink traps....Maybe someone else can give you advice about the waterlines..

Generally you blow the lines dry with a small air compressor. Remove the sinks stems and put non toxic anti freeze into the lines. Non toxic anti freeze is available at any RV supply and is pink in color. Remember to trip the tub diverter, so that the water held in the shower line will also drain, if not, it will freeze and break the line within the shower wall. Non toxic anti freeze will in fact freeze, but it actually shinks as opposed to expanding and thereby creates no problem. Another caution, anti freeze can cause damage to PVC tubs and showers, keep it in the drain only. Blow out plugs are also available where you purchase the anti freeze.
