"I called Mr. Rooter because I had called another Plumbing company to come out the night before and they were a no show.  They were extremely friendly over the phone.  I called at approx 8AM and said they'd be able to come out by 11AM.  They called at about 9:30 to say someone was available to come out now and I said that was perfect.  They arrived at 10AM.

Jason was the plumber who arrived and he was very very friendly and professional.  I told him the problem and we discussed pricing up front.  I had a coupon which he said they would definitely honor.  He immediately got to work.  He wore footies over his shoes while in the house.  He worked diligently and answered all of my questions.  After about an hour and being certain the line was clear he cleaned up, we took care of payment which was exactly what was discussed beforehand, and he was on his way.

A very pleasant and hassle free experience.  I will definitely be calling Mr. Rooter for the Franklin County area again for any plumbing needs and would recommend them to anyone needing this kind of work.

The job also comes with a 30 day warranty which I thought was great and definitely put my mind at ease just in case something happened again."

"They were very good. I had two different residencies. So I used one of the Angie's List big deals at each location. They were on time, very prompt and professional. They were very easy to work with. I was very pleased. With regard to price, they were very reasonable. I didn’t feel like I was pressured to buy anything additional that I didn’t need. They told me exactly what was going on. Their responsiveness and punctuality were very good. I love the email system that they have. As soon as I buy a coupon, they send me an email and say let's schedule this. I love that because it's a very easy way to communicate without having to get calls all day. I would absolutely sue them again in the future. I have to give them extra kudos as well because I did have two residences. I had my Harrisonville address on record. I was waiting for them 6:10.9 to 6:15.1probably about 15-20 miles away from this address. I thought that they would be out here anytime. Then it dawned on me that I did not give them the updated address. So I called them immediately and said that it was my mistake for sending them the wrong address. They were very gracious in owning up to my mistake."

"Tim gave us an honest evaluation of our existing water heater and options for repair or replacement. We decided to replace the water heater and Tri-State scheduled the next day. Installation was professional and l think Tim is the kind of craftsman you want representing your organization. The fact that you install the Rheem brand helped close the deal."

"We had Jones Air & Water come out to install filtration and replace a catalytic core system that we had installed to prevent descaling. In our situation, we had a high volume of Chlorine in the water that you could definitely smell and taste. The catalytic core system, didn't live up to the expectations and we still had to deal with a heavy scale build up noticeable on all of our faucets and with two Rinnai units for on demand hot water that raised concerns about what type of build up we were having on what we couldn't see. Everett came out and was very thorough in testing the water and then explaining a recommended solution. We finally decided on a dual media tank solution that Everett and JD installed that provides us with an efficient way to not only handle the Chlorine issue, but truly conditions the water and we're noticing all of the differences that Everett explained we should see. We are very satisfied with the whole process from the review of what our situation is, the recommended solution, the installation and the end result. We highly recommend using Everett for a water treatment solution."

"Overall, Rebath people are pleasant to work with. Brendan was a top notch craftsman, 'BJ' in office stayed in touch as work progressed. there were some problems with ordering product, receiving wrong product, miscommunication in scheduling, which delayed completion of job beyond our expectations. However job was completed to our satisfaction at last, and quality of product and of work are good.

"I hired this pro because he was honest about how difficult it is to deal with cutting tile around faucets in these old houses. He recommended cutting a big portion so the tile could be repaired if it broke but I would need a tile person to come in and fill in the tile. When he heard it was my only bathroom he figured that he could pull the dishwasher in the kitchen and do the installation of faucet and shower head from the back wall without disturbing any of the tile. Even though he was more expensive I appreciated his problem solving and who knows how expensive it would have been to deal with damaged tile that was impossible to match? I am pleased with the results. My only criticism is that it was discovered there had been a mouse infestation behind and beneath the dishwasher and he charged me a large sum to clean that up. I did it because I didn’t want to stop the project but it seemed like $350 was a lot to charge me for that."

"Mr Sam did a wonderful job removing a bad water heater and installed a new one. He also reconfigured my plumbing under the kitchen sink and installed a new sink and faucet. He was on time, polite, patient with my son who asked a million questions, and left a tidy workspace when finished. I am excited to hire him again for my many other projects that are needing done. I highly recommend this company."

Water Heaters FAQs, answered by experts

If you want instant hot water and to reduce water waste while improving convenience, a hot water recirculating system is worth it, especially if you find your hot water heater is not hot enough. These systems can save thousands of gallons of water each year so you don't have to wait for hot water at faucets and showers. The upfront investment can be high, especially for systems requiring additional plumbing, but the long-term savings on water bills and added comfort make them a worthwhile upgrade.

It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.

No. Expansion tanks must be installed on the supply side (where heated water flows out) of the boiler. There’s also a list of other requirements for most boilers, including being above the pressure relief valves, being on the inner side of any circulator, and more. Your installation manual should have more information on expansion tank installation requirements and what sort of tank the system is made for.

Electric water heaters use a high amount of electricity, so they’re best for homeowners who subsidize their electric bill with solar or who live in an area with inexpensive electricity. For others, gas water heaters versus electric water heaters may be the more cost-effective solution, with the added bonus of heating water quickly and efficiently. No matter which you choose, you can lower your water temperature as low as possible to keep costs down.

Due to the high temperature, using stainless steel vent pipes for your tankless water heater’s exhaust vent is best. Also, it is safe to use a flexible vent duct as the exhaust fan. If installing the exhaust fan yourself, make sure you are using heat-resistant silicon to connect the exhaust vent and the duct on your water heater.
