Hey all,
I live in Canada and our winters can be quite punishing. Also a couple times now when I've drained my tub I've gone through the annoyance of having to bleed the pump lines and in the winter that's just more frustrating....
So what I do is drain the tub halfway, but more often. So about once a month I throw a water pump in there and pump half out onto the snow in the back yard. Does anyone see a problem with this? Is there any reason why a full drain is better?
