I posted this a few weeks ago in the general repairs area and didn't get a response so I thought I'd try one more time, in plumbing. 

I have a 20 gal. Raritan water heater and I am wondering if anyone out there has ever used a Bi-pass kit when winterizing. If, is there an off the shelf version or did you make it? Pics would be helpful.I

Thanks
