"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.

"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."

"I held off renovating my bathroom because of the stories I heard from friends about their bad experiences. If I’d known sooner about Bath Planet, I wouldn’t have had to. They are outstanding! I’m extremely happy with my new bathroom and appreciate the team that handled the job. They really listened to what I wanted and helped me every step of the way with the design process, and responded to any questions and concerns. The craftsmen paid unbelievable attention to detail, were meticulous in their work during the entire job, respectful and so easy to work with. They completed the job on time and within the budget."

"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."

"When the service guy arrived he asked what our problem was and showed up the price chart.  He was not pushing any other service and gave us all the details on why the drain was clogging.  He wore lilttle booties to protect our floor and put a rug down while he worked.  Used the rotor to unclog the sink and he even double checked that the drain was cleared.  Also came with a warranty if the same drain should clog again.

Plumbing questions, answered by experts

Yes, you can water plants with water softened with potassium chloride. Potassium is a vital nutrient for plants, so using this type of water is harmless and can even be enriching. It is often a better option than water softened with sodium chloride, as too much sodium can build up in the soil and make it difficult for plants to absorb the water they need. If you notice that your plants are not tolerating the treated water, try letting it sit in a watering can for one to five days to allow the chlorine to diminish.

A water pressure regulator, also known as a pressure-reducing valve (PRV), is typically located near the main water shut-off valve where the main water line enters your home. Common places to check are basements, utility areas, or outside near the water meter. The device is usually bell-shaped. Its purpose is to control the water pressure coming into your home from the public supply, protecting your pipes, plumbing fixtures, and appliances. If you can't find a regulator, your home might not have one. In cases of high water pressure, installing a PRV is recommended.

Plumbing remodels typically require permits to ensure all work complies with local building codes and regulations, helping to maintain public and environmental safety.

Different plumbing systems may sound different when a pipe is about to burst, so sounds alone are not a definitive indication of a burst pipe. However, dripping sounds indicate a leaking pipe, and there’s a thin line between a small leak and a bursting overflow. Metallic sounds like clanging and rattling are common when a pipe bursts, though they can also indicate a normally functioning hot water system.

Toilet augers are hand-held drain snakes. Most of them come with 3 to 6 feet of cleaning cable and a curved, plastic elbow sleeve to protect your toilet bowl. If your clog does not go beyond the toilet’s wax seal, a 3-foot auger would be sufficient. Otherwise, you may need a 6-foot auger to unclog the drain.
