I finished putting my loop together but I would like a straight run from the pump to the front radiator. I was going to install a rotary fitting on either end but I've read that quite a few people experience leaking with those. Does anyone have recommendations for fittings that will work that aren't known to leak? Also, how often should the orings be replaced on fittings? Does everyone do it each time the loop is drained?
