My fountain pump is not pumping.
I've filled the fountain with water but pump is not pumping.
First of all, plug the pump in somewhere else to make sure the outlet is working. Plug it in while it's in a bucket or pot of water. Does it work in there? If not, check where the intake is. In there is an impeller, like a propeller except it sucks water in instead of pushing it away. Is the impeller turning? If not, unplug it and try to loosen it up with a screwdriver, turning it like you do a garbage disposal when it stops working. Now put it back in the bucket and try again.
If it is working in the bucket, it's not going through the tubing in the fountain. If it's a huge fountain check all the plumbing fittings and hoses. If it's a tiny table top fountain, check the fittings as well. On small fountains there is a place to regulate the flow. Check that - it's usually something circular where you can turn the water higher or lower.
If none of those things work, return the pump. It's faulty.
