I have a Ridgid SP-500 sump pump that is only 1.5 years old. It will drain the water out of the pit and it sounds fine but when it empties the water it keeps running and then makes a loud noise like its just sucking air since there’s no water. This happened a few months ago and all I did was unplug it for a couple of hours then when I plugged it back in it was fine. But now that it happened again so I’m assuming something is wrong. In doing a little research I see things saying that it could be a switch problem or maybe a bad check valve. Also I saw about drilling a hole in the pipe just below the check valve or drilling a hole just above the discharge on the pump. I don’t know anything about that so that kind scares me. Does anyone have any ideas what the problem may be? I can replace a check valve or the entire pump but I don’t know anything about replacing a bad switch.

My husband and I are buying a house.. we close in about a week. The seller put in a brand new side by side fridge, but it is not hooked up to a water line.. and we totally didn't think to have them do that in the agreement for us. So, we are going to have to do it when we get the house. We are really wanting to do it ourselves. I've been reading that it's pretty easy to do.. and we really want to save the money. The question is, how do we do it? Even though a lot of things say it's easy, it still sounds kinda difficult to me. Also.. the sink is on the opposite wall, so we will have to hook it to the washer.. which is right next to where the fridge is on the other side of a wall. So, I hope we can run it from there?? Should we use copper or plastic wire? How long does it take? We kinda need an easy to understand step by step guide. I'm really hoping we can do this. The laundry room/washer/dryer lines up with the fridge.. there is just a wall between them. The garage is on the other side of the wall they are on. And actually the people who lived in the house before had the washer/dryer in the garage just flipped the other way from where they are now. We decided to put them back in the room. So I believe the water hookup is actually in the garage. But it's still the same wall everything is sharing. Also.. we are on a crawl space.. and it's a wood foundation.. so it'a s little different than your typical crawl space. The only entrance to the crawl space is inside.. it has no inlet from the outside. It's completely enclosed. We would greatly appreciate the help!!
