Drain the water heater first, then while the hose is still attached, open and close the inlet valve a few times to help flush the sediment out. Do this until the water comes out clean. You may have to dismantle the valve if large chunks of scale are coming loose. With the anode out, shine a flashlight inside the tank to inspect for rust.

I had a sewer line that needed attention. RayMay was unable to busy to get someone here for couple days. They called me back about 30 minutes later to tell me they found another plumber that could come the same day.

We had a leaking water pressure regulator, which started after having concrete work done. I had ordered the parts online from a big box store and was planning to rebuild the regulator myself. After waiting ten days for delivery, I finally called to check on the status. I kept getting a "your delivery is being prepared" message. It took three days to get through and they told me my delivery was being prepared.

At this point I called Ray May to see if they had the rebuild kit in stock. They didn't. He told me they don't stock them because the rebuild kits don't work very

I have used Ray May Plumbing several times now and can't say enough good things. Steve in the office goes out of his way to be helpful, whether answering basic questions or finding something no other big box stores carry. Their technician Alex is professional, prompt and has always treated my house as if it was own. They are straight shooters with old school customer service you just don't find anymore. Absolutely can't go wrong with Ray May Plumbing!

Rude and unprofessional. Dealing with Ray May Plumbing today showed me just how poorly their customer service is and how greedy they are for every last dollar.

Another great repair job with Ray May. I had a plumbing issue that turned into a construction issue. They solved all my problems quickly and on budget.

I've been a loyal customer of Ray May Plumbing for nearly a decade. They are thorough, professional, fast, and are fairly priced. Anything they have installed or done in my house has lasted. They also have been good about suggesting the timetable of certain kinds of maintenance, such as clearing the pipes draining the washing machine (dog hair can clog it up and cause a backup).

I cannot recommend this business enough. I have been in search for a part that was missing from our shower since we moved in to our new home a few years ago. The single piece that was missing is not sold separately and therefore I would have had to spend a lot more than necessary just to replace the handle that was somehow un-screwed and misplaced. I was recommended RayMay plumbing by my usual plumber. He told me to call and ask for Tom. Not only did Tom go way above and beyond to help us track down the missing piece, but he ended up calling a rep who was able to unscrew the piece from a floor

This is my first experience at this establishment and I am thoroughly impressed. I do some plumbing but I'm no expert by any means and Tom behind the counter was very helpful. The store is beautiful, clean and well laid out. And the customer service is the best I've ever had in a plumbing store and I've been to quite a few of them. Tom is very knowledgeable and generous with that knowledge. My best experiences at these places are when I learn something new. That was certainly the case this time. I highly recommend Ray May Plumbing.

They replaced my sewer pipe to the street. They had to hand dig the whole thing due to tight quarters. The guys work hard and they are very quiet. I really didn't even know they were working unless I looked out the window. This is a great company and they do  very good work.

What service! I needed a toilet handle on a Saturday that wasn't something I could find in a Home Depot. This place didn't have it in stock as well, but took it off a floor model for me.
knowing it would take up to a couple of weeks to order.
