We were referred to Monster Plumbing and he came fixed it and told me if I had any more problems to call him again. Two later again toilet clogged. He came out with a scope and found some type of wiring that the builders dropped in during our rebuild after a fire. Pulled it out and what a relief super job!!! He was very assertive that he would find the problem. GREAT JOB!!!"

Len The Plumber, LLC. is a leading plumbing and drain company serving Central Maryland. Our certified professional plumbers are available same day to assist residential customers in Anne Arundel County, Baltimore City, Baltimore County, Carroll County, Cecil County, Harford County, and Howard County. Our knowledgeable plumbers have years of experience dealing with a wide variety of plumbing issues including plumbing repairs, drain cleaning, water heaters, well systems, heating systems, sewer, water, and gas lines. We’re open 7 days a week with no extra charge on evenings or weekends!

"I’ve used Len the Plumber in the past, but after today, I will never be using their services again. I called to follow up on a recent (and expensive) drain repair - work that my family stretched our budget to afford. The plumber who came out was great: professional, kind, and respectful. But unfortunately, the drain is still not fully cleared. When I called customer service to ask if there was any warranty or guarantee on the repair, I was met with nothing but attitude. I wasn’t rude, I simply asked a question. Rather than receiving a straightforward answer, I was spoken to in a condescending and dismissive tone, as if I didn’t have the right to inquire about a service I paid a significant amount for. If the answer is “no, there’s no warranty,” then just say that. I would’ve scheduled another appointment and paid for the additional work. But I refuse to support a business that treats its customers like that over the phone. I hung up and blocked the number. To whoever runs this company: please take customer service seriously. It’s hard enough to pay steep prices for plumbing work—being treated rudely on top of that is unacceptable. Hire people who are kind and respectful to your customers. You’ve lost my business."

"We recently needed our Bosch Dishwasher to undergo some serious repair work. Bad hoses, some new parts for the pump and it all had to be done with it removed from its little cubby hole under the kitchen counter. Replacing the 4-year-old dishwasher was not a financial option. This, low decibel, (40) model, sells in the vicinity of too much. $1400 plus. It is extremely quiet, very efficient, and appreciated, considering our family TV viewing area is basically in the same room, the Family Room being open to the Kitchen Area. I contacted three appliance services. Only one responded. Russel’s Appliance Service. In this case the “right” one. We set up an appointment, he was right on time. The estimate for repair, parts replacement and labor was exceptionally reasonable and well within the scope of practical. That was after nearly three labor hours to remove the unit. With a tremendous amount of efficiency, cautious and careful manipulation, and a couple of bushels of patience he was able to get the dishwasher out. The cabinet installers did not correctly attach it to the cabinets, and it was installed by the previous owners before the hardwood flooring was installed in the kitchen. Meaning it sat on the subfloor. Which made it quite a task to remove. Parts had to be ordered and two trips later Mr. Russell, again delving into those patience bushels, was able to make the necessary repairs and re-installed the dishwasher into its cubby hole…correctly. If you need service or repair work, dishwasher in our case, we would not hesitate to contact it needed for stove or refrigerator, you need to call Russel Appliance Service."

FAQs for water heater installation and replacement projects in Darlington, MD

You'll need an expansion tank if your home has a closed water system, which is standard in newer homes or those with backflow preventers or pressure regulators. Expanding hot water has nowhere to go in closed systems, creating potentially damaging pressure. The expansion tank provides space for this expanded water, protecting your plumbing system and water heater from premature failure. Many local building codes now require expansion tanks, and some water heater warranties may be voided without one.

For a standard 50-gallon water heater, a two-gallon expansion tank is sufficient. This sizing assumes normal household water pressure between 40 and 60 psi. If your home has higher water pressure (60 to 80 psi), consider upgrading to a slightly larger tank for added protection. The expansion tank's purpose is to accommodate the increased volume that occurs when cold water heats up, which is proportional to your water heater's capacity.

Watch for signs like dripping water around the tank, fluctuating water pressure throughout your home, or unusual noises in your plumbing system. A properly functioning expansion tank should feel light when tapped on the bottom—if it feels heavy or waterlogged, the internal bladder has likely failed. Other indicators include frequent triggering of your temperature and pressure relief valve, visible corrosion on the tank, or unexplained increases in your water bill, suggesting hidden leaks.

Most expansion tanks have a service life of five to 10 years, though some may last up to 12 years or more with proper maintenance. Factors affecting lifespan include water quality, system pressure, installation quality, and tank construction. Hard water areas often see shorter lifespans due to mineral buildup. Regular maintenance checks can help identify potential issues before complete failure. When your water heater is due for replacement, it's wise to replace the expansion tank simultaneously, even if it hasn't failed yet.

A 30-gallon water heater needs an expansion tank if your home has a closed plumbing system. The need for an expansion tank is determined by your plumbing system type rather than water heater size. Even smaller water heaters create thermal expansion when heating water. If your home has a backflow preventer, pressure regulator, or check valve on the main water line, you have a closed system that requires an expansion tank. Check your local plumbing codes, as many jurisdictions now mandate expansion tanks regardless of water heater size.
