This is the FPH Idea Of The Week.   Get yourself one of those attach-to-faucet rigs, attach it and use it when you need to.   Other than that, uninstall it and take it with you.   If you leave it installed, they’ll break it out of spite.   If you’d like to go more compact/lightweight, check out the hiking/camping type water purification systems.   You can find them online at REI, EMS and Campmor.   Get a good lock on your bedroom door, get one of those small college dorm type refrigerators, keep it in your room so you’ll always have a couple pitchers of cold, purified water.   Good luck with your quandary.
