This pump works to remove all of my used water from my RV from the place where the water stays until I remove it. I usually have 100% in my water tank and then I use this pump to delete the used water tank and this pump works very well as it deletes the water very quickly, just a few minutes, as I turn it on and then off when the water tank is down to no more water. I love this pump!
I have not installed it. I have put them in before. I don't see any problem, unless the new one is defective.
It most likely will work fine.
