What is the average cost of a check valve installed

Sorry Zhuzhu, but we don't estimate prices online here as each area of the country has different pricing schemes.

If you are unsure of a local plumber's pricing on a job, call in one or two more for a free estimate and see what they can do for you, OK?

Good luck!
