HL Bowman has been in the same location for 38 years and owned by the same family for over 65 years. HL Bowman is a non commission based company. HL Bowman employees will never upsell you a product you don't need. Dennis and Bryan Enders and his family have deep roots in the Harrisburg community. After 65 years Dennis and family stay committed to giving the community the best possible service and product to fit their needs. HL Bowman has won Angie's List super service award every year.
"Adding to the above review: NEGATIVE STARS 1. The Daikon' ductless mini-split' unit, sold to me by Brian Enders and installed by H.L. Bowman Incorporated, unleashed a deluge that not only saturated the hardwood floor in my dining room but also flowed onto bookshelves and drawers in the room below, drenching 25 family photo albums. 2. The water pooled atop and between each section of my quarter-sawn oak Stickley barrister bookcase. 3. The water seeped inside each section of the bookcase. 4. The water ran onto particularly important and expensive books, framed photographs, as well as four small wooden boxes containing four of my dog's cremains. 5. In past years, water from a second-floor unit emitted sufficient water to cause a 12' by 5' section of the upstairs floor to crash through to the main floor. All furniture and items in that 12' by 5' section were so water-damaged that they had to be discarded. Water ran behind the plaster and into the wiring contained within the plaster walls. I had to make an insurance claim to have that water damage repaired. 6. In past years, water from a basement unit emitted sufficient water to cause an entire wall of built-in cabinetry to be destroyed and have to be replaced. I had to make an insurance claim to have that water damage repaired. 7. In past years, four of the six "ductless mini-split" units have simply not worked. They do not cool. They do not heat. They hang on the wall and blink. 8. Throughout these years of destruction, distress, and financial duress caused by the six 'ductless mini-splits,' Brian Enders has consistently refused to rectify the problem. 9. The FIRST REASON Brian Enders uses to refuse to rectify the problem: When the ceiling caved in from the upstairs unit and the cabinetry was ruined by the downstairs unit, Brian Enders offered substandard assistance. He sent a contractor to my home to spackle over water-damaged plaster, thus sealing water inside the walls. When I saw the inferior repairs Enders offered, I stated that I was going to call my lawyer. Enders said that because I had threatened legal action, his company would no longer serve me. 10. The SECOND REASON Brian Enders gives for refusing to rectify the problems: When the ceiling caved in from the upstairs unit and the cabinetry was ruined by the downstairs unit and Brian Enders offered substandard assistance, I wrote bad reviews of Brian Enders and his company "all over the internet." (Enders words.) Yes. I did, indeed, write bad reviews of Brian Enders and his company, H. L. Bowman, Incorporated, "all over the internet" and will continue to do so until Brian Enders and his company, H. L. Bowman, Incorporated, make the six Daikon "mini-split" units they installed in my home work properly. 11. Because Brian Enders and his company, refuse to help me, I have paid five other companies, & one private contractor, to come to my home to diagnose and repair the six Daikon "ductless mini-split" units. Each one has been unable to do so. Each one says that there is something so faulty about these units &/or the installation of these units that it is impossible to determine what is actually wrong with them. 12. On Saturday, June 22, 2024, I tried to set up a service call with H.L Bowman, Incorporated, using a form on their website. 13. On Saturday, June 22, 2024, I received a text from H.L. Bowman confirming an appointment for Monday, June 24, 2024, with a note relating that on the day of the service, I would receive a call 30 minutes before the technician arrived. 14. On Monday, June 24, 2024, I instead received a phone call from H.L. Bowman informing me that they are too busy serving their VIP customers to send a technician out to serve me. Today is Tuesday, June 24, 2025. H.L. Bowman has still not rectified their financial and material injury to me."

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.
