Winthrop Supply Co.

An amazing plumbing supply store available to the public and businesses. Great help for DIYers and seasoned professionals. Everyone is super personal.

I read a posted review while at Lowe’s - “I’ll never go to a big box again.” They did not have what I needed, nor the people to advise me. I went to Winthrop’s, saw three plumbing contractors’ trucks in front, and thought “this is the place for me.” I was right - helpful, completely prepared for my needs, and very cost-effective. I’m a customer for good now.

Winthrop is the best plumbing shop in the world !

Great place with super helpful staff! They have me for free 2 PVC drain fittings to try, which one would be right for me. Brought them back with peace of mind, no receipt needed, just on a good word. An awesome old school store.

I am NOT a plumber and I went into Winthrop looking for a replacement packing nut for a really old water shut off valve that was leaking. I didn't get the name of the gentleman that helped me but he was really helpful and gave me a length of graphite rope gratis and said it was probably my best bet as a band aid for fixing my leak. I ended up buying a complete valve assembly with a packing nut that looked comparable to mine and using the packing nut from that to fix my leak (which worked), but I appreciate his willingness to help and that he wasn't condescending like a previous place I had been. The leak is fixed and I have already recommended this place to others. There is sometimes more than one way to fix a problem and he didn't assume I was incompetent. That goes a long way in my book.
