We at State Plumbing Supply have been doing business with W4 for approximately 30 years. I can confirm their excellent customer & tech services. Highly recommend.

W4 is able to provide valuable product information that you cannot find on the manufacturer’s website.  Their product knowledge is the result of dealing with every facet of the products that they sell.  From the engineer that designed the product to the end user of the product – knowledge that can only gained through experience.

Having top of the line customer service, while supplying top of the line products makes it an easy choice to go with W4 over other suppliers.

W4 has always been great to work with and their customer service is spot on. It’s always easy to reach someone and get inquires answered promptly. I appreciate their well stocked inventory and their ability to “build” a part when needed.
