Sizing a Rheem Tank for Carrollwood Fixture Count and 1970s Plumbing
Carrollwood's 1960s through 1980s ranch builds across Original Carrollwood, Carrollwood Village, and the Lake Carroll corridor share a specific plumbing signature: cast iron drain stacks at peak failure age, original 3/4-inch copper supply with the inside wall narrowed by 50-plus years of mineral scale, and gas line drops that pre-date modern tankless BTU demand. We measure fixture-unit load, calculate effective inner pipe diameter, and bring every Rheem install up to FBC 2023 Plumbing Chapter 5 spec. FREE in-home estimate. FREE diagnosis on every visit.

Three Carrollwood Specifics That Change Our Water Heater Installation
Effective Pipe Diameter After 50 Years of Scale
An original 3/4-inch copper supply in a 1970s Original Carrollwood home has often lost 20 to 35 percent of its effective inner diameter to mineral scale and pitting. That means a nominal 3/4 inch may flow like a 1/2 inch. We pressure-flow-test the line before recommending a Rheem tank or tankless size. A tankless rated for 7 GPM at 70 degree rise will not perform if the supply line can only deliver 4 GPM under load. This is the most common reason homeowners call us after a competitor install in Carrollwood fails to satisfy a parallel shower draw.
Pressure-flow test included on every Carrollwood install estimate.
Anode Rod Selection for Tampa Water
Tampa Water Department serves Carrollwood at 5 to 7 grains of hardness, on the lower end of moderate. That hardness extends standard magnesium anode rod life to about 5 to 6 years. However, the higher chlorine and chloramine residual in Tampa city water reacts with magnesium and produces a sulfur smell on hot water draw, a complaint we hear weekly from Carrollwood homeowners. We install Rheem units with aluminum-zinc anode rod by default in Carrollwood (about $35 in parts) which eliminates the sulfur reaction and extends rod life past 8 years.
Aluminum-zinc anode upgrade kills the sulfur smell and extends rod life.
Cast Iron Drain Stack Coordination
A water heater install in Carrollwood often surfaces a related problem: the original cast iron drain stack serving the kitchen and laundry is at 50-plus years and near its joint-failure inflection point. We document the drain stack condition during every Carrollwood install estimate so you can decide whether to do drain work in the same trip. Combining the work saves a return permit fee and a second crew mobilization. Hillsborough County permits both jobs under one application when scheduled together.
Combined permit available when paired with drain stack work.

Rheem Performance Tank vs Performance Plus Tankless: Carrollwood Math
A Rheem Performance 50-gallon gas tank costs $1,750 to $2,400 installed in Carrollwood (Peoples Gas serves most of the area) and runs 8 to 12 years. Annual standby heat loss runs about $90 to $120 per year on gas. A Rheem Performance Plus 9.5-GPM tankless costs $4,800 to $6,500 installed, lasts 15 to 20 years, and eliminates standby loss completely.
For a typical 3-bath Carrollwood Village home with adequate 3/4-inch gas service and Peoples Gas already at the meter, the tankless ROI penciling out at 8 to 11 years through standby savings and extended lifespan. For Original Carrollwood homes where the 1/2-inch gas drop and tight mechanical closet would both need rework, the Rheem Performance 50-gallon tank avoids about $1,200 in gas line and venting upgrade cost.
Carrollwood Water Heater Snapshot
- Typical water hardness: 5 to 7 grains
- Average build year: 1968 to 1985
- Tank lifespan: 8 to 12 years
- Tankless lifespan: 15 to 20 years
- Standby savings (gas): $90 to $120 per year
Aluminum-Zinc Anode for Tampa Water Sulfur Smell
If you have ever smelled a rotten-egg odor coming out of your hot water tap in Carrollwood, you are not imagining it. Tampa Water Department residual chlorine and chloramine react with a standard magnesium anode rod to produce hydrogen sulfide gas in the upper tank. The reaction is harmless but the smell is bad. The fix is replacing the magnesium anode with an aluminum-zinc rod. We do this by default on every Carrollwood Rheem install (about $35 in parts) and we can also retrofit it on an existing tank as a service call.
