2500+
Connecticut homes served with plumbing and heating work
35+
Years of hands-on plumbing and heating experience
Mansolf Plumbing and Heating serves Southington from our shop in Wallingford, a short run west across Route 322. We're family-owned, licensed and insured in Connecticut, and we bring more than 35 years of hands-on plumbing and heating experience to the work. Boiler service, water heater installation, and general plumbing repair make up most of what we handle here.
Southington has no shortage of long-established plumbing companies, and we're not going to pretend otherwise. What we offer is a different working relationship: you talk to the people doing the work, you get a real diagnosis before an estimate, and the price we quote is the price you pay. Call or text 203-815-6276 and you'll get a straight answer about when we can be there.
Boiler Repair
Gas and oil boiler diagnosis and repair, from no-heat calls to short cycling and uneven zones.
Water Heater Replacement & Installation
Tank and tankless installation sized to your household, permits and code compliance included.
Leak Detection & Pipe Repair
Non-invasive detection using acoustic sensors, thermal imaging, and pressure testing, then a permanent repair.
Drain Clearing & Clog Removal
Kitchen sinks, tubs, toilets, and main lines cleared without harsh chemicals or guesswork.
Boiler Service Across Apple Valley
Southington's older neighborhoods run heavy on hydronic heat, which means boilers rather than furnaces. The village centers at Plantsville, Marion, and Milldale hold much of the town's original housing, and the streets ringing the Town Green on Main Street include Colonial, Federal, and Victorian-era homes where heating systems have been retrofitted more than once over the last century. Those systems are workable and they take a careful hand, because what's actually installed rarely matches what the original design intended.
We handle the whole system rather than just the appliance sitting in the basement.
- Gas and oil boiler diagnosis, from no-heat calls to short cycling and uneven zones
- Circulator pump, zone valve, and expansion tank repair and replacement
- Annual inspections, cleanings, and combustion checks
- Radiator and baseboard diagnostics on retrofitted and multi-zone systems
- Full boiler replacement when a repair no longer makes financial sense
If your heat is out right now, that's
boiler repair and it's the call to make today. If you're ahead of the season and want to stay that way,
boiler maintenance and tune-ups is the visit that keeps January quiet.

Hot Water That Keeps Up With Your Household
Water heater work is the other half of what we do in Southington. Most tank units last eight to twelve years, and the failure pattern is predictable: hot water runs out sooner than it used to, then recovery slows, then you find water on the floor. Catching it at the first stage means you choose the replacement on your terms instead of picking whatever's available on an emergency call.
We install both tank and tankless systems, sized to how your household actually uses hot water rather than to a square-footage rule of thumb. Permitting and Connecticut code compliance are part of the job, not an add-on line item. If you're weighing the two options,
water heater replacement and installation walks through the tradeoffs in detail.
Why a Wallingford Company Covers Southington
Fair question, since Southington sits on the I-84 corridor between Hartford and New Haven while most of our service area clusters around Wallingford and New Haven. The answer is straightforward: Southington is roughly twenty minutes from our shop, closer than several towns we've served for years, and the housing stock has a lot in common with what we work on daily. Older homes, hydronic heat, aging pipe materials, and oil systems that eventually need replacing.
That proximity is also why we can commit to same-day service on most repairs here rather than putting you three days out. We're covering Southington, Plantsville, Marion, and Milldale, and if you're near the Apple Harvest Festival grounds or out toward the orchards on the west side of town, that's still us.
What Our Clients Say About Us
Stay Ahead of Repairs With the Care Club
Care Club membership covers your annual plumbing and heating inspection, priority scheduling ahead of non-members, discounted repair rates, and waived emergency fees. For an older Southington home on a boiler, the annual inspection usually pays for itself the first time it catches something before the cold does.

Southington Plumbing and Heating Questions
Who services boilers in Southington, CT?
We do, on both gas and oil systems. Mansolf Plumbing and Heating handles boiler repair, annual maintenance, and replacement throughout Southington, Plantsville, Marion, and Milldale, including older retrofitted systems in the village centers.
Do you offer emergency plumbing service in Southington?
For no-heat calls in freezing weather, active leaks, and burst pipes, call or text 203-815-6276 and we'll get you into the schedule the same day whenever we can.
How far is Mansolf from Southington?
We're based in Wallingford, roughly twenty minutes away. That's close enough that same-day service on most repairs is a realistic commitment rather than a best-case scenario.
Do you work on homes near the Southington Town Green?
Yes. The neighborhoods around the Town Green and along Main Street include some of the oldest housing in town, with heating and plumbing systems that have been modified over decades. That's the kind of work we do regularly.
Will you quote me over the phone?
We'll give you a range and tell you what we think is happening, but we won't hand you a firm number for a system we haven't looked at. You get a written price after the diagnosis and before any work starts.
