does backflow proventer have to be removed in winter or very cold weather?

Instead of removing you can drain the backflow preventer. In my opinion, it was easier to remove than drain.

I leave mine outside all year round. I plug it in as soon as there is a nip in the air but as others have said it does not "heat" the water, it just keeps it from freezing. Our temps this winter have been well below zero and I noticed some ice on the water but usually it is OK. It is exposed to all types of weather elements from heat to rain to snow and there is no trouble. Racoons, possums, birds, and cats have all come to get a drink from the bowl all year. You do have to monitor the water level.

It is essential that the unit be in a location where it will not freeze up. Even with an indoor installation, my daughter's unit froze and was destroyed because the exhaust pipe allowed very cold air to feed into the unit when the 'flapper' valve got lodged open.

Should not be a problem as long as it is in the shade and the temp does not get below freezing. If the temp does then it would have to be drained or the pump will crack from the frozen water.

I can't answer this from experience since I have not owned the unit through a heating season. Technically, the manufacturer recommends disconnecting the intake hose from outdoors during the winter and using inside air as the intake during cold weather. I am hoping that does not become necessary, but it may.

Every 6 months, I defrost it manually. Not a big deal. LOVE IT! Better than I expected for the money! Low cost to run too.

Not sure what the all weather kit is but I do know that it will condensate and drip so plan accordingly. So if it is extremely cold and you anticipate dripping make sure the exhaust doesn't become blocked with ice. I am not a certified installer but I do know you don't want this blocked.

It depends on how much salt your cars going to see through out your season. Iv'e had mine for two years in NC and do a detailed clean on it every 6 months. Its held up after three winter storms were we had massive amounts of salt on the road. I dont think any exhaust system will be spotless in a Northeastern winter though. Since this is cheap you could get away with buying a new one every two years if it gets bad.

Cold air comes out of the exhaust, so, yes, you have to exhaust it outside. You want to pull the inside air as the feed though, so block off the air intake hose.

I think you will be fine. I take just the cylinder off during the winter (very simple and easy to do on my cold frame) because i don't think it would take the brutal NY winter. Not knowing much about your conditions, i would expect that AZ in winter is similar to NY in spring when i start my plants. There are nights that go below freezing and I've never had an issue.

No, you need to prime it. A check valve at the end of the intake hose/pipe means you will only need to prime it once, however. It is O.K. for outdoor, but I use a small enclosure over the top. It must be protected from freezing. Wayne pumps are tops in my book, and I have used dozens of pumps.

I have a pond myself and what we normally do is take the filter indoors over the winter and not let it run because we had a filter before that completely froze over while we had it running during a winter and it broke the filter. It all really depends on where you're located and matters of preference . I've seen people who do leave them out during the winter and they're just fine. Personally, I like to take ours in.

It tries to disperse the water back into the airflow. The dual model is designed differently, it has the outside air incoming into the motor cabinet and that same air is then sent back outside. Yes, I leave mine out year-round, as I also use the fan mode for white noise in wintertime.

No, however you are not supposed to leave the pump plugged during winter season as the water on the cover will likely be frozen as well. Hope this answers your question.

Not all models have auto defrost which is important for colder locations, this model has that feature, also the fact that it has pump mean you do not have to go down to the basement and constantly empty the bucket. You probably have some kind of drainage tube (I think it require by code) that you can send the hose to but you only need the pump it you are going upward to a sink to automate the removal of water. Since basement are damper and colder you would want moire capacity then if upstairs so you probably want the bigger unit.

I have not used in freezing temperatures. Heated waterer is best, they have one similar to this. This is the best waterer for regular use.

Depending on where you live. If you have heavy snow fall you should treat your heater as you do your A/C unit. Snow can get into the heat transfer fins and with melting and freezing can ruin the exchanger. I have my external equipment heater, filter and A/C in one area so I built a roof over them with walls to protect from the weather.
