What should it cost to have a sewer pump replaced? Including the price of the pump.

A household sewer ejector pump? Too vague a question. What size horsepower or GPH? Some run from $150 to $1400 depending on quality, voltage and capacity. Also depends on union-non union labor costs in your area, difficulty of access, how much plumbing has to be removed, what else may have to be replaced, brought up to code and others. Contact 3 plumbers and get estimates.

You have to give us more info. But generally speaking, it depends where what part of country you live in and what city. But figure, average residential pump may run you around $500 and the labor depends where the ejector is. It may easily be another $500. You may also need new check valve and few fittings to reconnect

If you are little handy, you can replace it yourself and save on cost of labor

Hope that helps
