Half draining tub instead of full?

[hanexs]

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?

This is certainly a viable alternative in your climate for wintertime.  I would time it so you can do a full drain and refill as late in the season as possible, then as early in the spring.  During the winter, a partial is better than nothing.
