So, one is leaving the house empty for 3 or 4 months. I will shut off the well pump, set the thermostat to @60 deg. Put some lights on timers. Buy the neighbors a box of 12 gauge shells --
The question is what to do with the sink traps so they don't go dry and let sewer gasses back up into the house. I plan on filling the toilets high, and maybe putting something like clingwrap over them to slow down evaporation. I am thinking of pouring a cup of olive oil in the sink traps, or is there something better to use?
Thanks for any help.
