Question: Does this pump have an automatic on/off when water is present?
Document: Nice little pump! Its not the fastest thing in the world, but its a definite work horse. It pumped down my in ground pool in about a day with no problems. The pool water was solid green with a bunch of leaves and debris floating around in it, and this pump had no problem pulling the water out even with all that junk in it, never clogged once.
This pump is a work horse that really works well in shallow water. I use this pump to clear Spring run-off from my garage;  it has never failed me. This purchase is my second, and I only bought it because I love my current one so much that I wanted to have another in the event my older one (now 6 years old) fails.Works well to clear deeper water as well.
Easy, straight forward, quiet and strong running. Well worth the $$$ for what it can do. Due to it's design it takes the water down in the space to minimal amounts. Have used it for a couple months now and very satisfied.
Handy and lightweight for quick removal of water from a clogged sink or in my case basement water in some areas of seepage. Works quickly and is easy, just attach a hose and drain the seepage right down to the bottom 1/8th inch. Beats trying to sweep water to a sewer hole.
Best pump on the market. 20' cord very handy, and as always showed up on my door step right on time.
If they made the inside of the impeller where it mates with the D shaft of a harder material such as stainless, then this pump would be a work horse.
I sent this as an aid since the whole area was sold out. IN short it worked great. Several of her neighbors bought the same pump. It did work down to the 1/8 inch as advertised. They were very happy to have it as an adjuct to their sump pump.
I have a number of utility pumps that I use for a lot of jobs. this one constanty needs new impellers at $15-$20 a whack. A pain to fix and my other pumps don't fail like this. The issue is the D shaft off the motor is stainless steel, but the impeller is plastic. The small flat side of the inside of the impeller constantly breaks and the D shaft free-spins in the impeller, leaving the pump useless.
Works great. Very efficient. Does the job quite well. I a very pleased with the product. Would recommend this to a friend.
I've tried several different pumps over the years. This one pumps up hill well, pumps down to 1/8" on a flat surface and pumps faster than any other I've had. It's not loud and can run empty without over heating since it just has a impeller and a motor rather that rubber parts that wear on other pumps. Some pumps have a annoying little anti siphon type device that has a little sprayer (those suck!)
Answer: yes
