plumbing question

[netimreefer]

I am building my sump and was wondering I have a 1.5" bulkhead on the built in overflow, the question is my return pump is fitted for a 1" pipe, how do I make the two fit and work together and where can I get the pieces to complete this task?

If it's PVC get a 1.5" to1" reducer or split the 1.5" to two 1". The big home centers have what you need.
