If I place the pump about 3-4ft above the reservoir and sump should I still add a check valve? I'm thinking I shouldn't have to worry about backsiphoning with the pump up higher than both.

As long as the output tube is above the waterline this should work fine. It is a good idea to test it first just to make sure, but I see no issue with this.

Great thanks. Just ordered the ato with float valve and pump. Hope it works on my rubbermaid stock tank sump.

Would this pump draw ok if my reservoir was about 10 ft away from the pump?

Absolutely no problem with this, it can push many times that amount.

What is the recommended max run time on these? I know they are not good for continuous, but is there a limit? Is it a cooling issue such that cycled on and off with cooldown time, it could run for a total of 1-2hr per day?

I use two ebay peristaltics now to do a slow water change daily, roughly 3 gallons is pumped out with roughly 10ft of head pressure. Standard pump is used to "top-off" with fresh salt water during this time period. The peristaltics were cheap but loud and I need to replace them with something better now that I know the process as a whole is feasible.

They have a 25% duty cycle so 6 hours a day. Occasional use over this will not kill the pump but will reduce its life. We tested for 7 weeks continuous use 100% duty cycle before failure, they are tough little pumps.
