the jet pump housing has a BIG crack in it. New pump/motor combos are in
the neighbourhood of $400 up here in the GWN.

Should I just get a housing (if I can) or put a whole new pump on the end of
the still perfectly good motor?

We have a heater cable around the inlet pipe - the power went out.

Is there any kind of gadget that would protect us from this problem if the
power goes out again?
