"I would not recommend Hester Plumbing for the elderly. Brian, the owner was arrogant and curt, always in a hurry, and spoke very rapidly. I believe he is driven by money, not customer service. He told us not to go through Angi and to cancel our install with Lowes after he found that there was no way to install a switch without getting an electrician involved. We also had a couple of other small jobs we needed done. He said to buy a starter and he left. We bought the starter at Lowes and cancelled the install. He said e would install the disposal and do the other small jobs when he returned. We waited a couple of day for him to call and set a new appointment. We the missed the appointment because of an emergency. I apologized. He called several days later and we set another appointment. He was fast and efficient during the time he was here and charged us for the missed call. That was fair, but he never disclosed that he would do that. I discovered it when I questioned the bill. Anther plumber told me up front that we would be responsible for a $90 service fee, for the visit plus labor and materials. The $90 would be applied to the final bill. Brian disclosed up front that by putting the hole in for the start button, there was a chance it could shatter the sink. I pictures our sink in pieces, but we gave him the go ahead. When he left, he did not point out that there was a small chip by the start button and I did not do a close inspection because it was obvious that the sink was not in shatters. When I thought Brian's install could have created another issue that arose after he left, I left a humorous VM message. He called and pointed out my error. I apologized. He did not accept my apology or get my sense of humor, nor give me time to explain. He was in a hurry to reinforce how wrong I was. I said goodbye in tears and then texted him saying that there was a chip in the surface of the sink where he installed the disposal start button. I was concerned that water might leek through into the cabinet. I asked if needed silicone caulking. He never replied. If he had given me a yes or now answer, I could have done the silicone my self. It he gave good customer service he would have returned do the caulking."

He had the water heater, expansion tank, lines, valve and drip pan replaced in about 90 minutes. He was very friendly and answered all my questions about the install. His work was first rate and the heater even had a plate with his name and installation date. The price was $1000 even, and that was less than half of our other three estimates.

Sun Tap's competitors worked hard to "sell us" their system, but did not have the expertise necessary to convey the comprehensive solution that Sun Tap offered...plus, their systems were double, triple the price!" - Miranda Soeder "It is also a pleasure to let you know what a fine job your installers did. They were most courteous and pleasant. They were here at the time they scheduled and were quickly finished. They left my home neat and the only visible sign of there presence here was my new system tucked neatly away in my garage and under my kitchen sink. It is a real pleasure when you see installers take such pride in their work and who leave the property they were working on unharmed and clean." - Rosemary O'Donnell "Rick's willingness to go out of his way in customer satisfaction has been one of the hallmarks of the Suntap Water service. The two systems that Rick installed have worked flawlessly over the years and it is always a pleasure to have Rick and his son out for the annual service of the systems. They are prompt, efficient and courteous. I truly prize my long term relationship with Suntap and have come to rely on them for all of my in-home water needs." - Crane Day "We decided on Sun Tap for a number of reasons but we were most impressed with his concern for what our property would look like after the install. He suggested that we put the tank in the garage to keep it out of sight (something that our CCR's required) and further convinced us to install an RO unit after we tasted a sample of the water. He appeared honest and offered us other customers of his to contact for a reference. Over the years the service has been outstanding. I don't even have to remember to have the service done because I receive a card in the mail when the yearly service is due." - Bob and Tonya Messenger Visit our website to read the full reviews and reviews from other satisfied customers.

"JC came to our home, inspected the water connections and gave us a quote for installing the water treatment system. Our home was built with a loop and drain already installed, so this offered a simple installation for the water softener. We were able to schedule installation for the following week. Dave and crew arrived at the appointed time and performed the installation quickly and efficiently. The connections under the kitchen sink were a bit tight, but Dave managed to successfully work around the existing plumbing and garbage disposal to install the water filtration system which is connected directly to the icemaker and water dispenser in our refrigerator. We no longer need to buy bottled water. There is a soft water tap in the garage we can use for washing cars. The system works very well for us, and the cost was very reasonable when compared to quotes we received from other companies for similar systems. Sun Tap also offers to deliver salt when needed and pour it into the tank for us."

Water Heaters questions, answered by experts

Every city and state will have its own set of installation codes and laws. Some won’t require you to obtain a permit before replacing your water heater, though we recommend you do, regardless of the local codes. On the other hand, some cities and states might require secondary permits for plumbing and electrical work related to the installation. Check with a local water heater installation company and local building codes to confirm which permits are required and what the specific laws are.

You can use multiple tankless water heaters, but that doesn’t mean you should. Adding multiple tankless heaters adds considerable cost to your home in both parts and installation costs. Also, you’re adding many more points of failure in the system, making plumbing issues harder to diagnose. More heaters mean more maintenance, and insurers may want a word regarding the increased risk of water damage. A single, larger unit makes more sense in most situations.

Signs that your water heater needs replacing include rust or corrosion on the tank, persistent leaks, inconsistent heating, strange noises coming from the heater, decreased efficiency, and visible damage. Water heaters over 10 years old may also need to be replaced. However, in some cases, these issues can be fixed with a repair rather than a replacement, so make sure to consult a pro before investing in a new water heater.

Often, the first issue you might encounter is a lack or loss of power—this could be caused by a tripped switch or a failed heating element. If your hot water is not producing enough power and its size is not the issue, you might need to replace one of its heating elements. A leaking water heater could be caused by tank erosion.

A larger heater requires a larger breaker—unless there’s one already installed. The longer answer to this question is more nuanced. Do you place demands on the heater at the same time as running other heavy-duty appliances like ovens and washing machines? Do you live in an older home that may not have considered the higher electrical demands we have now? Breakers need to be sized at 125% of the load. To find that load, you should call a local electrical pro.
