If your sump pump needs replacing you may be able to do it by yourself without the need for calling in a plumber to help you. This can save you quite a bit of money.
However if you're putting in a brand new sump pump and drain line, you should probably get some professional help unless you're very experienced at the job. Putting in a new pump can be difficult, but if you have to just replace a sump pump, it's not too hard.
When you replace sump pump, the first thing you need to do is find the pump and then make sure you unplug it. This is an important safety measure to make sure you don't injure yourself or suffer an electrical shock.
You then need to locate where to disconnect the sump pump from the drain. This shouldn't be too hard as it is generally a screw-type union or coupling with clamp connections on it. Either way, you should be able to disconnect it pretty easily and quickly.
Once it's unhooked, you should remove the sump pump from the pit and let it drain out for a several minutes. If you see any fittings or pipe from the water outlet that connect to the drain, you should take them off and keep them for the new pump.
To make sure that you replace a sump pump with the proper model, take it to your local plumbing or hardware outlet. They should be able to help you find the right replacement pump that uses the same power source and comes with similar same drain-line hook-ups and pumping functions.
When you get the pump home, just reattach all the piping and fittings the same way they were hooked up on the original pump. Then put the new pump in the pit and reconnect it. Be sure to plug the pump in and test it. If you can replace a sump pump by yourself you'll definitely save some money.
