Got home from work today to find the return shut off valve on my Odyssea leaking. After pulling it apart and finding no obvious cause, I decided to temporarily eliminate it. The hose return to the tank would not fit over the output directly, so with a few bits from around the house and a quick trip to the hardware store... I made a temporary fix. I will be adding in a proper ball valve in the near future, but for now, no more leaks.
