"I consulted Angi on Easter Sunday April 20, 2025 after the septic backed up into the shower the previous night. Called several of the listed vendors; however, the only one taking call on the Holiday was Routerproxpress. The only reason I chose this company was because they could come out on Easter Sunday. They told me that they would arrive between 2 and 6 pm. I had a call at 4:30 that their trucks tanks were full and there was no place open on Easter to dump the trucks tanks. They rescheduled to Monday April 21 between two to six. I requested that they come after 4:30 since I had a very important appointment with my bank. They said they could arrange that. At 3:20 I had a call from the technician that he had located the tank and instead of the $500 quoted on the phone It would be $887, due to the large size of the septic tank at 1500 gallons and a large amount of solids. This seemed high but I wanted the problem taken care of ASAP, so I okayed the work. He also told me he thought there was a break in the line between the septic tank and the cross over line to the drainage field. Quoted over $6000 for the repair. I told him I wanted to get a second opinion and estimate before I would approve any further work. I also asked if it would be possible to use the toilets, sinks, and showers for a week or two while I did so. He said that would be okay. I instructed him to put the cover back on the tank and leave the dirt off the top. Later that night, the septic backed up again, this time flooding the basement. I contacted the office who called a manager John. John came out to see what happened at my request. He told me that he would call a water mitigation company and that routerproxpress or insurance would take care of it. A company called Propertymedics called me shortly and came out at 2 am on Tuesday am on April 22. They were pressing me to sign a work contract but I informed him (Claud) that Router pro xpress had called them out and said they would be responsible for the water mitigation. Claud said he suspected a blockage rather than a break in the line. I called the RXP office on Tuesday April22, ultimately speaking to the owner, Jeff. I explained that I was quite unhappy that we had flooded after the technician said it was okay to use the sinks, toilets . I was suspicious that the technician hadn t emptied the tank considering he was gone when I arrived 20 minutes after he had called me. And he had misdiagnosed the problem and given us the wrong information about using the sinks, toilets and showers. I said I would give him a poor review, contact Angi, and was considering a charge back to my credit card. He said the work was already done and he would put a lien on my house if I did. He said he would send a crew to do the repair and I better be ready to pay the $6000 plus bill then. I told him he should come with the crew and I would be there in person. The office said they would be out between 2 and 6 pm. In the meanwhile, I was planning to have another service provider out to diagnose my septic problem and get a quote and to be on hand when RXP showed up."

I’ve been a plumber for about 9 years and I love what I do! My company is all about the American way, providing the best goods and services at the best prices possible. We appreciate your business:)

"This company exceeds my expectations. Austin is knowledgeable and strives to meet all your needs. I hired him to replace a hot water heater, but he ended up finishing other plumbing projects that my renovation contractor failed out. Justin also came to assist and was great. This is my forever go to Plumbing Company."

"Due to pinholes in our 1980 home copper pipe system we needed a complete re-pipe done. Contracted with Plumbing Express. At 9 a.m. four of their specialists went to work with protecting our floors then got busy opening walls and removing the copper pipes. They were all friendly and professional and worked well together. By 6 p.m. we were back in business with all new cpvc piping and our home tidied back up. Our home has 3 bathrooms and the usual appliances and sinks and everything was working when they departed. Impressive! A couple days later their sheetrock guy came out and patched the walls and ceilings and matched the stippling perfectly in the ceiling. They delivered as advertised. I highly recommend Plumbing Express."

"Our project was originally to start on November 13th and take 3-4 weeks. Due to 4 days of rain and other projects he had to finish, it was started later than planned. On the second day, Jamie texted to say someone’s car broke down on the way to our house and they’d be late. Later in the afternoon, we were advised the vehicle was in the shop so the crew couldn’t come. (There were 4 vehicles here the day before so we weren’t sure why one in the shop took the whole crew out.) They resumed work the following week. He asked in the beginning if we had any particular concerns and we said yes, two. One, our grandchildren, 2 of whom are toddlers, are here often so care would need to be taken to keep nails and hazardous garbage picked up when they leave for the day. Two, they would need to keep the gate to the pool closed and either cover the pool or be careful in that area. Most days, we walked outside to find the gate left open and nails and pieces/slivers of wood, paint chips and other garbage littering the yard and deck. We went out one day after they left and realized they had been using the pool deck to cut the material for the facia, siding and trim. On these days, the pool was littered with sawdust. We were past Thanksgiving and heading into Christmas and no end in sight. The gutters had yet to be done weeks after the painting was finished. We were wondering if this job was more involved than this company typically handles or if a good project manager was needed. We had to remind him of the same things multiple times because nothing was written down. There is paint on the front porch rails, paint on the pool deck and on the outside of the screened porch. There’s overspray everywhere. We did have a walkthrough, and they did take care of the things we pointed out. At the same time, as the months have passed, we continue to find areas that need touch up. We will need to purchase paint and must touch things up ourselves. The biggest problem we had ended up being with the way the drip edge along the roof line was handled. Four months prior (in August) we had our roof replaced including new drip edge. We were assured that when replacing the facia that the drip edge would be fine. If there were spots that needed to be touched up, they would handle it. By the time the work was done, the drip edge was in bad condition with warps and bends to the point that we insisted it be replaced. At first, Encompass pushed back stating that the drip edge had been installed incorrectly. However, the the roof and drip edge were installed correctly by a professional roofer but damaged during the facia replacement. Encompass did consult with a roofer who told them that there should be no problem replacing the drip edge, so they proceeded to do so. Their work in replacing the original drip edge was better than they way they originally left it, but it was far from the condition it was after our roof was replaced. One of the reasons the drip edge was so important to us is that we just had bats removed from the attic and wanted to have the drip edge prevent that from happening again. In addition, after spending over $58,000 on our house, we weren’t happy with the finish of the drip edge. Since then, we’ve started getting estimates on what it would cost us to have the drip edge properly replaced. So far, we’ve received an estimate of $19,000 for the work. Because there is so much of it that has been damaged, it would cost more to cut and replace only the damaged parts and leave the few places that are not damaged than to replace all of it. We are also seeing wasps go under the drip edge, which was not happening prior to the work Encompass performed. After spending over $58,000 on the work, we are extremely unhappy to be looking at numbers this large to ultimately finish the work."

Tankless water heater installations FAQs

Yes, although they have a higher upfront cost compared to traditional units, tankless water heaters can be worth the investment for many homeowners. They heat water on demand, eliminating standby energy losses and leading to 24% to 34% greater energy efficiency for homes using up to 41 gallons of hot water daily. Tankless units last longer—around 20 years with proper maintenance—and require less space than traditional units. They also reduce the risk of leaks and water damage since there's no tank to corrode and fail.

Tankless water heaters, including gas-powered models, do require electricity to operate components like the ignition and control systems. This means they won't function during a power outage. If you live in an area prone to outages and want to ensure a continuous hot water supply, consider installing a battery backup system or generator to keep your tankless water heater running when the power goes out.

You should set your tankless water heater to 120 degrees Fahrenheit for optimal safety and efficiency, as recommended by the U.S. Consumer Product Safety Commission. Setting the temperature at 120 degrees prevents scalding accidents, particularly for children and the elderly, and reduces energy consumption. Temperatures above 140 degrees increase the risk of burns and promote mineral buildup, which can decrease the system's efficiency.

A 20-minute shower uses 50 to 60 gallons of water, assuming a flow rate of 2.5 to 3 gallons per minute. A typical whole-house tankless water heater can produce 4 to 8 gallons of hot water per minute, providing continuous hot water for long showers. By installing low-flow showerheads and reducing shower time, you decrease water consumption and energy costs, maximizing the efficiency of your tankless system.

With proper maintenance, a tankless water heater lasts around 20 years, significantly longer than conventional tank water heaters, which last between 8 and 12 years.
