We had countertops installed before the holiday and the plumbing company we used could not install our sink hardware in time, we called every plumbing company within 10 miles and Kay was the only one that could come out. the day before Thanksgiving! They were professional, accommodating and genuinely friendly and caring to our needs."

"Conrad's team is amazing. They were unbelievably fast and efficient. They fixed both of my fireplaces today and gave me valuable advice on maintaining my units. I will definitely be giving them a call in the future for any other issues or routine maintenance."

- CJ Disharoon

"The gentlemen were very professional, not pushy, they explained what they were going to do and the options we have. Not only did they originally come only to replace a broken tubing from the dishwasher, they rearranged the pipes under the sink, then we hired them to replace the 4 toilets we had. They came on time, and very professionally completed the job. Our in law also had taken a business card from them for a future reference as they are having a home built."

- Gerald Baker

"Kay Plumbing and Bryan are our Go To plumbers for any plumbing need. They installed our Tankless Water heater and our néw shower fixtures when we converted our tub to a shower. They regularly clean our water heater and Always provide excellent, competent and professional service. Bryan is friendly and very helpful. It’s nice to have a plumber on call that you can depend on and trust to do a good, honest job."

- George Folsom

"I explained to the Kay Plumbing guys what I needed done and they gave me a detailed estimate of what they would do and how much it would cost. The prices were fair and they did a great job taking care of a small gas leak and descaling the tankless water heater. Most important of all they were honest enough to say that I did not need to replace some pipes that were rusted which saved me a lot of money. It is a pleasure to work with people who treat you with respect and are so professional."

Frequently Asked Questions (FAQs)

Should I insulate my water heater?

Yes, you should insulate your water heater! An insulated water heater can save you 10% of your water heating costs and typically the insulation pays for itself within a year. However, you’ll want a professional to perform the installation to get the best results.

Why does my hot water run out?

Your hot water may run out for a variety of reasons including: a leaking hot water heater, a faulty heating element or thermostat, or sediment buildup. In some cases your water heater may simply be undersized for your needs and you may need to install a larger heater or a tankless water heater.

When should I replace my water heater?

You should replace your water heater once it requires frequent repairs, or if it is more than 10 years old. Old water heaters pose a greater risk of failure, possibly leading to expensive water damage, and newer models generally heat up more quickly while using less energy.

How hot should hot water be?

A household water heater typically heats up to between 140 and 160 degrees Fahrenheit, but 120 works for most people. It’s important to keep all family members in mind when picking the right temperature; too hot of water can scald or burn someone.
