I am replacing a sump pump as part of a basement remodel. The old pump is plumbed with a 1.5" PVC line a couple of feet up to the check valve. From the valve to the outside it's 1" copper.
Is this a code violation or a bad idea and why? I don't want to charge the client for extra work (to replace the copper piping) if it's not necessary.
