"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!"

"They called right back, and arranged my appointment for the next day. They gave me a 4 hour window, and arrived on the early end (called to let me know their plumber was on their way). He diagnosed issue, fixed it and cleaned up after. Price was reasonable. Will definitely call them in future for other plumbing needs"

"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

No. You should never directly drain a water softener into a sewer cleanout. This practice is illegal in many areas because it could allow raw sewage to get into your drinking water and make you seriously ill. Many places have codes requiring a specific seal, pipe, and a large air gap between a water softener and a sewage cleanout. Check out Florida's Plumbing Building Code as an example of what these restrictions might look like.

The amount of water wasted when a toilet ghost flushes depends on the cause of the ghost flushing. Leaky flapper valves tend to waste less water than a larger problem like a damaged flush valve that makes the toilet run constantly. Even if you don’t think you’re wasting a lot of water, it’s still a problem that should be fixed quickly. 

Common problems include leaks, clogs, and low water pressure. Regular maintenance prevents major disruptions.

A house has two main water shut-off valves. One water valve location is inside the house. If your home is connected to a municipal water supply, you’ll find it on the perimeter of the house on the side that faces the street. If your home uses well water, that valve could come in from any side. The other main valve is near where your property meets the street.

Some older homes have toilets in the basement to combat sewage backups. This type of toilet, also known as a Pittsburgh potty, acted as a safety valve over the incoming sewer line. If a line backed up, it would back up into the toilet because it was the lowest fixture in the home, keeping it out of sight and away from the finished areas of the house.

Basement toilets were also used by workers with messy jobs, like those who worked in coal mines or steel mills. This way, they could clean up and avoid tracking dirt through their home.
