"Kirkwood Plumbing was very responsive, sending a highly qualified technician within 24-hours. He did an incredible job replacing old cast stacks and vents to our 2nd floor bath. The further comment that I would make is they are not cheap. I'm still trying to reconcile their cost for a 7-8 hour job, but the results couldn't be better."

"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."

"Great presentation by Nick. Very nice, informative, professional and knowledgeable. Super quality products and vert6competitive pricing. Because of very busy installation schedules, it will take 4-6 weeks before walkin shower remodel can happen. We can wait, no problem. It will be worth it."

"as installed in 2010, which is correctThe plumbers did arrive about 1 hour and 40 minutes into the 2 hour window.  I explained the problem.  They asked me to show where the drain went in the basement.  They estimated it was about 55 feet from the kitchen sink that would need to be cleaned.  They said they would perform a whole house plumbing inspection while there.  While one plumber worked on the drain the other checked for natural gas leaks, there were none, and checked the water heater.  They told me the water heater was installed in 2010, which is correct.  He also told me the anode rod needed replacing.  I googled anode rods and found 2 references from plumbing supply companies that verified everything he told me.  They also sold me an enzyme to maintain the drain.

Plumbing questions, answered by experts

Yes, you can fill your toilet tank manually to help it flush, or you can pour the water directly into the bowl to flush it manually. This will work for the majority of toilets, as most use a gravity feed system. However, you should only ever use this as a temporary solution. If your toilet tank isn’t filling, you should find out why. First, make sure the speedy valve connected to your toilet and your water main are open. If that doesn’t solve the issue, call in a professional to address the problem.

Deteriorated seals, O-rings, or gaskets are common culprits behind a leaky sink after you’ve turned off the water—especially if your sink is older than 15 years. Inspect each of these mechanisms in your sink for signs of corrosion or looseness, then replace the worn-out part to fix it. Older sinks may be worth replacing if several of the parts are worn-out.

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 key difference between a standard spigot (or regular hose bib) and a frost-free hose bib is its design to prevent freezing and pipe bursting during cold weather. A standard spigot is a basic outdoor faucet. In contrast, a frost-free hose bib has a longer stem that extends into the heated interior of the house, placing the shut-off valve inside where it's protected from freezing temperatures. This design, often combined with a downward-sloping supply pipe, ensures water drains out of the faucet body when turned off, preventing ice formation. This allows you to leave the water supply on year-round without the risk of pipe damage, making it a valuable choice for regions with harsh winters.

Left unattended, a leaking toilet will eventually cause water damage or mold growth. If you’re a homeowner, you can file an insurance claim for water damage. However, that can be a long and tedious process; sometimes, your insurance company may not cover the damage. Therefore, it’s always best to fix any leak you notice right away if you can.
