M&N Plumbing Supply Co. has been a family-owned, trade-focused wholesale supplier since 2002. We stock what contractors actually need — pipe & fittings, HVAC, hydronics, waterworks, tools, and more — from the brands you trust, with the people who know the product.

Pipe hangers, supports, fasteners, electrical, septic products, home automation, and the professional tools to get the job done.
M&N Plumbing Supply Co. was founded in 2002 as a wholesale plumbing supply company built specifically for contractors and trade professionals. Our Greeley location serves Northern Colorado with the same personal service we've built our reputation on — real product knowledge, fast counter service, and people who treat your job like it's their own.
We carry over a hundred manufacturer lines across plumbing, HVAC, hydronics, irrigation, waterworks, and more. When you're on a job and need the right part fast, we're open at 6:30 AM and our counter staff know the inventory.
Open accounts for contractors, plumbers, mechanical firms, and municipalities. Competitive pricing, invoicing, and a team that knows your business.
We stock deep across every category — so you're not waiting on a special order for common parts. Counter pickup, same day, no runaround.
Our staff know the product. Ask about specs, compatibility, alternatives — you'll get a straight answer from someone who's seen the same problem before.
From single-family new builds to large commercial mechanical projects — we supply both, with the right products and pricing for each.
Browse products, check availability, and manage saved carts at mnplbgsupply.com — then pick up at the Greeley counter or request delivery.
Unmatched knowledge and service. I will never look for plumbing supplies elsewhere. Spencer was so helpful — 10 stars on service alone.
Great company to work with, especially if you're a smaller company trying to get off your feet. Whole staff is great. They have all the supplies we're looking for. Highly recommend.
Staff can answer any questions and help you find anything plumbing related. Excellent stocking of all kinds of hard-to-find things. Good location for any of your plumbing needs.
