• Installation requires some household tools and novice plumbing skills. If you replace your own kitchen 

and bathroom faucets, you can handle this!

• Installation may require drilling a hole in your sink top.  A variable speed drill and specialized drill bits 

may be needed.  We highly recommend professional installation!
