Winterizing no pink in hot water lines

In answer to Offgrid - all my plumbing was done with the cheaper crimps.  I recently had a leak under my sink, and used a combination of sharkbites and the clamp rings to fix it, along with some new Tees.  Two of the connections were not accessible with the borrowed crimping tool, so I had to use the sharkbites instead. 

Glad it’s worked out for you.

I would leave the old bypass open in winter just to be sure any condensation that might get collected in it drains into the water heater tank. In summer close it so it doesn’t create a hot to cold “short circuit”.

I just winterized and had the same problem with the anti-freeze not coming through the lines to the sink and the problem was I forgot to put one of the two sets of low point drain caps on and it all got pumped out and fast, and felt like a fool! I assume the same will happen when another tap is left open. Lucky the stuff is only a couple bucks a gallon at walmart!

Originally posted by ampete I'm rethinking postponing the plumbing project till spring.   If I were to do it now, can I tackle it after the steps of draining the fresh water, hot water and low drains? Good time to work on the new bypass?

Originally posted by offgrid The objection to auto antifreeze for plumbing is that it attracts animals and is toxic and bactericidal. So, don't put it on food surfaces but also don't put it on the ground or in a septic system. So where do you drain it safely?  It also costs more than RV antifreeze so why use it for a purpose for which it isn't intended?
