"Called today for a non-emergency service (no water leaks at the moment).  I scheduled an appointment for the following week.  A couple hours later they called and said they could come today.  Jason arrived a few minutes later.  He was very friendly and professional.  He reviewed the damage from the leak (we had turned off the water).  He was able to quickly determine the likely cause.  After making the fix he double checked to ensure the problem was fixed.  I really appreciated his expertise and ability to ensure the fix worked.  I also appreciated his friendly demeanor.
I have used Kirkwood Plumbing before and they will be the first for me to call.

"Maplewood Plumbing was the 2nd company I called to replace a garbage disposal after the first company was blatantly trying to rip me off. The plumber they sent was on time, friendly, honest (he didn't try to upsell me models) and was less than a third the price of the 1st company I had called. Thankful for a company I can trust, I will absolutely use them again in the future!"

"Outstanding Service from Express Services Plumbing! I had a fantastic experience with Express Services Plumbing. From the moment I called, their team was professional, courteous, and incredibly responsive. They quickly diagnosed the issue, explained everything clearly, and completed the work efficiently without cutting any corners. What impressed me most was their attention to detail and respect for my home—everything was left clean and in great shape. The plumber who came out was knowledgeable, honest, and clearly took pride in his work. It’s rare to find a company that combines quality service, fair pricing, and top-notch customer care like this. Highly recommend Express Services Plumbing for any plumbing needs—definitely my go-to from now on!"

"The people on the phone and the workers that worked at my house were fantastic. Damien and Ernest were the installer's top rate people. Jack, their license plumber was polite and funny. The only person we didn't care for was Keith He only stopped by to look at what was going on. He was a little rude to my wife and Made her feel Like she was second class in her own home. We Were very shocked by that. We would definitely recommend Jacuzzi to our friends."

Plumbing questions, answered by experts

Yes, a toilet, sink, and shower can share the same vent. This is a common plumbing practice that can simplify installation and save space. When sharing a vent, it's important that the toilet is located downstream from all other fixtures. You will also need to ensure the vent pipe is large enough to handle the demands of all connected fixtures without compromising its effectiveness. Because requirements can vary, you should always check your local building and plumbing codes. Consulting a qualified plumber is recommended to ensure the vent is properly sized, installed, and adheres to all local regulations.

A toilet flapper will remain open when the chain that it is connected to is too short. The chain should lift the flapper just enough to allow it to open the rest of the way on its own. The chain should have just about half an inch of slack.

Running water can help melt ice inside the pipe, but only up to a certain point. If your pipe is frozen solid, adding water will not likely resolve the issue. Water will begin to flow through the affected pipe once the area is heated by a plumber, signaling the issue is getting resolved.

The air admittance valve, or AAV, is a spring-loaded mini-vent that sits right next to your washer. It acts in place of a standard vent stack connection, opening to let air into the drain whenever pressure builds up. It otherwise stays closed to prevent sewer gas from escaping into your home. This gives the washer’s plumbing system the air it needs when water enters or drains.

Start by inspecting visible pipes for signs of corrosion, moisture, or discoloration, which can indicate a leak. You should also listen for sounds like hissing or dripping, which may point you toward a leak. Moisture meters and infrared cameras can also help you identify areas of increased moisture around your home, which can also signify a leak.
