Water Heater Services in Lewisburg PA

Plum Perfect Every Time

Tank units, tankless, boilers — we handle every type of water heating system throughout Union, Snyder, Northumberland, and Lycoming counties.

Water Heater Repair

 Lukewarm water, strange noises, a unit that runs constantly but can’t keep up — these symptoms all have specific causes. We find the actual problem and give you an honest assessment. Sometimes it’s a $150 element. Sometimes it’s time for a new unit. You’ll know which before we start.

Water Heater Installation

 
New construction, home additions, or adding hot water to a new location. We size and install correctly from the start — right venting, proper connections, and code-compliant work throughout central Pennsylvania.

Tankless Water Heater Installation

 

Endless hot water and lower energy bills are the two reasons most central PA homeowners switch. We assess whether your home’s gas line and venting can support it — and walk you through the full picture before you commit. No pressure either way.

Water Heater Replacement

 
When repair doesn’t pencil out, we replace your unit the same day in most cases. We carry common sizes on the truck and size the new unit correctly for your household — not just whatever’s in stock. You won’t be stuck without hot water for days.

Water Heater Maintenance

 Annual flushing removes sediment that quietly shortens your water heater’s life and degrades efficiency — especially in areas with harder water. We also inspect the anode rod, pressure relief valve, and all connections. An hour of maintenance versus an early replacement.

Tankless Water Heater Repair

 
 
Error codes, temperature swings, no ignition, inconsistent flow — tankless units require specific diagnostic experience. We work on Navien, Rinnai, Bradford White, and other major brands and carry common parts to get you back up fast.

Tankless Water Heater Conversion

Switching from a tank unit to tankless is a bigger project — new venting, gas line sizing, and sometimes electrical work. We walk you through the full picture before you commit so you can make an informed decision. No pressure either way.

Signs Your Water Heater Needs Attention

Most water heater failures don’t happen without warning. Here’s what to watch for — and what each symptom usually means.

No hot water or running out fast

 

Could be a failed heating element, a tripped breaker, a failing thermostat, or a unit simply undersized for your household. Worth diagnosing before replacing — and we’ll tell you which it is.

Rumbling or popping sounds

 Sediment accumulates at the tank bottom and creates these sounds as water heats through the deposits. Flushing can help if caught early — but if the tank is far enough gone, these sounds mean replacement is coming.

Your unit is over 10 years old

 

 Tank water heaters typically last 8–12 years. Once yours crosses a decade and starts showing symptoms, repair costs rarely make financial sense. We’ll tell you honestly when it’s time to replace rather than patch.

Water is rusty or discolored

 
 
Rust-colored hot water usually means the sacrificial anode rod has failed and the tank has begun corroding from the inside. This is almost always a signal that replacement is the right call — not a repair.

Water pooling around the base

 Any water around your water heater demands immediate attention. It could be a fitting, a valve, or the tank itself. Don’t wait on this one — slow leaks from a failing tank can cause significant damage to your floor and surrounding structure.

Energy bills climbing unexpectedly

 An aging water heater works harder and harder to maintain temperature as sediment builds and components wear. If your utility bills have crept up without explanation, your water heater may be working twice as hard to deliver the same result.

We’ll Give You a Straight Answer

We’ll always give you a straight answer on this even if it means a smaller job for us.
Here’s how we think about it.

Repair usually makes sense when...

Unit is under 8 years old
Problem is a single failed component
Repair cost is under 50% of new unit
No rust, corrosion, or tank leaks.
Unit has been well maintained

Replacement makes more sense when...

Unit is under 10+ years old
Multiple repairs in last 2 years
Repair cost exceeds 50% of new unit
Rust, corrosion, or tank is leaking.
Unit is undersized for your house

Here’s What Our Happy Homeowners Think About Knauss Plumbing

Water Heater FAQ — Lewisburg PA

How much does water heater replacement cost in Lewisburg, PA?
Tank water heater replacement typically runs $1,900–$2,800 installed, depending on size and brand. Tankless units run higher — usually $3,800–$5,500 — because they often require new venting and sometimes a gas line upgrade. We give you a flat price before we start. Call and describe your situation and we can often give you a realistic range before coming out.
How long does water heater replacement take?
Most tank water heater replacements take 2–3 hours from arrival to cleanup. Tankless installations typically take 4–6 hours because they involve new venting and sometimes gas line work. We’ll tell you what to expect for your specific situation before we start — no vague windows.
Should I repair or replace my water heater?
If your unit is under 8 years old and the problem is a single failed component, repair usually makes sense. If it’s over 10–12 years old, the repair exceeds half the cost of replacement, or the tank itself is leaking or corroded — replacement is almost always the smarter investment. We’ll tell you which applies when we come out, even if it means a smaller job for us.
Is tankless worth it for a Central PA home?
For the right household — yes. Tankless units last 20+ years versus 10-12 for tank units, use significantly less energy, and never run out of hot water. The higher upfront cost typically pays back over 8-10 years in energy savings. For smaller households or tighter budgets, a quality tank unit is still a great choice. We’ll help you run the numbers honestly.
Can you come out the same day for a water heater?
Yes — same-day service is available for most water heater calls in Lewisburg and the surrounding area. We keep common tank units and many common parts on the truck. Call us at (570) 568-1851 and we’ll tell you exactly what our availability looks like.
Do you also service boilers?
Yes — boiler installation, repair, and annual maintenance is a Knauss specialty. Many central PA homes heat with hydronic boiler systems, and most service-only plumbers don’t touch them. We work on all major boiler makes, handle zone repairs, circulator pump replacement, and full boiler replacements. Learn more about our boiler services →
What brands do you work on?
We work on all major brands — Rheem, A.O. Smith, Bradford White, Navien, Rinnai, Noritz, Weil-McLain, Burnham, and more. For tank replacements we typically recommend Bradford White or Rheem — quality manufacturers with strong warranties. For tankless, we most often work with Navien and Rinnai. We’ll recommend what makes sense for your home and budget, not just what we have most of in stock.
