5 stars. I was recently without heat and diagnosed it down to a faulty ignition. And of course this happened on a holiday. Found out about this place and discovered that they are open on Saturdays! Brought the part number and picture on my phone and was in and out in 5 min. Highly recommend!

Called to inquire if they had the part i needed, it was waiting for me when I got there, half the price of the lowest I saw listed on line plus no wait for delivery. This hot shower brought to me courtesy of Penn Plumbing supply 👍👍👍

The people who work here are amazing. I'm a new home owner and very new to DIY home projects but they took 10 minutes to walk me through what I needed to do for an issue I was having.
A part I bought didn't fit, they refunded and helped me find the right one. Just all around very helpful.
Absolutely going to these guys next time I need help with a plumbing project.
