"From when Darren came to initially quote the job to the final handshake, I got a good feeling for his ethic as a craftsman and a businessman. I felt no angling to empty my wallet and his demenor comes off as honest and true. The job entailed replacing original 1940's 'Orangeburg' asphalt drainage that periodically became infiltrated by oak tree roots and running new water lines to separate exterior garage as well as extending gas line for dryer out there. He rallied three teams and they knocked out a considerable amount of work in under 6 hours while doing a tight, professional job. The drain line had to be hand-dug due to the pre-existing one running alongside the natural gas line from the city.
I added a few tasks on job day such as hooking up the washer / dryer and a new gas range while removing a massive 1950's stove I love for it's look, but time to send to pasture for its poor operation, restorative cost, and poor thermal insulation. The added costs for these tasks were agreeable as anything gas related makes me think of bursting into flames; so it was reassuring to have craftsmen tending to it and the old stove was a 4-man manipulation because of sheer weight and the dimensions.
I will certainly recommend A Royal Flush should anyone need a reliable, skilled, and true plumber and look forward to saving up for the next conquest - an inline water heater installation.

Water Heaters FAQs, answered by experts

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.

Water expands when heated and also when freezing. When water is heated, it expands by around 4%. For a full water heater, this is one of the main reasons malfunctions occur—the hot water has nowhere else to go but out. Due to the constant expansion and reduction in volume, it’s recommended (required in most places) that an expansion tank be installed.

A well-maintained hot water recirculating pump can last 5 to 15 years. Pumps that run continuously may have a shorter lifespan than demand-controlled models. Hard water can reduce longevity by causing mineral buildup in the pump and pipes. Regular maintenance, such as cleaning or replacing filters, can extend the pump’s lifespan.

Depending on the brand of water heater, you may need to install an expansion tank in order to meet the conditions for warranty coverage. It’s important for consumers to read the fine print of the warranty to see if an expansion tank is necessary. Even if an expansion tank isn’t required for the warranty, it’s usually mandated by building codes—although not for tankless water heaters.

Traditional gas or electric water heaters last an average of six to 11 years. However, with excellent maintenance, they can last up to 15 years. Heat pump water heaters, on the other hand, last an average of between 12 and 15 years and potentially longer with proper maintenance. In both cases, your home's water quality can be a determining factor regarding the lifespan of your water heater.
