I just bought a sump pump and was given help at the store I bought it from. I tried to convey that the old sump pump was connected to 1" PVC pipe in my crawl space. The sump pump I bought had an adapter to accept either 1.5" or 1.25" PVC. The person that helped me told me to get 1.5" pipe. How do I convert the 1.5" down to 1"? Or do I need to return the 1.5" pipe I bought and get 1.25" so that it is not such a reduction? I figured that it could cause quite a bottleneck going down .5" in pipe size.
There are reducers available, such as 1.5" to 1". Just ask for what you need and connect it, either with threaded fittings or glued fittings, depending upon what type of pipe you're working with.

I thought that it wouldn't be a great idea to reduce the size of the pipe so much. I'll use the 1.25" adapter that came with the pump and buy a reducer to get the pipe to the 1" that I need. That is a much better reduction. And I'll do it right at the sump pump. Thanks for your help! I know how I'll be spending my Saturday morning.
The reducer isn't the issue it's having a pump made to discharge into a 1 1/4" pipe minimum choked down to 1", you will increase the work the motor has to produce to push the water through the smaller size pipe, drawing more amps to operate, over working the pump, it will wear out faster. Similar to plaque in your arteries causing your blood pressure to increase, adding to the load on your heart.
It doesn't matter wether you reduce the diameter from 1.5'' or 1.25'', there wont be any clogging nor will the pump use any extra power. Your diametric reduction will only increase the discharge velocity. An increase in diameter may cause the pump to get overloaded but reduction upto a certain point wont affect your job. Carry on wid any reducer.
