SEFFNER PLUMBER FOR PRESIDENTIAL MANOR, OAK VALLEY AND THE PLATS AROUND THE I-4 INTERCHANGE

Plumbing in Seffner, Where Each Plat Has Its Own Story

Seffner is the community around the I-4 and I-75 interchange, about 8.2 miles east-southeast of Temple Terrace City Hall. The ACS puts the median build year at 1989, with 83.5 percent of occupied homes owner-occupied and a median home value of $344,100. The plats nearest to us run 6.7 to 9.6 miles out.

Almost every Seffner address is on Hillsborough County South-Central water, which the county treats with chloramine at 3.8 ppm on average. Unlike the city to the west, there is no city utility here, so county Water Resources is the number to know for anything in the street.

Plat by Plat, From 1974 to 2005

Presidential Manor has 353 parcels built 1977-84; Oak Valley 302 from 1979-87; Oak Forest 131 from 1978-81. Together those three hold 786 parcels in the national polybutylene window, which is only a reason to look, not proof of anything. Nita Estates and Lazy Lane Estates are 1974-77; Lake Shore Ranch and Chestnut Forest are 1999-2005.

A leak or a repipe call in the older plats starts with the supply pipe's material. A call in a Lake Shore Ranch house, built around 2000, is more likely a first-generation heater, a toilet part or an angle stop. See plumbing repairs and the older-homes guide.

What Each Service Means From Kingsway Road to the Interstate

• Emergency Plumbing Repairs — A broken line inside a Seffner house is ours after the meter; a break at the meter or in the street goes to county Water Resources first.
• Plumbing Repairs — In the 1974-87 plats, worn toilet parts, corroded stops and weeping supply lines are the staples, with the supply pipe's material noted each time.
• Plumbing Installation — Fixture and bath upgrades in Oak Valley or Presidential Manor start by finding the original shutoffs and drain locations.
• Leak Detection — A rising county water bill with nothing visibly wet is the cue for a pressure test and listening survey.
• Water Heater Repair & Replacement — County chloramine and houses from 1977-87 mean heaters here are often second or third tanks, and we check the expansion tank too.
• Repiping (PEX) — Repipes follow the pipe material, so we look for polybutylene in the 786 parcels from the 1977-87 window before quoting.
• Drain Cleaning & Hydro Jetting — Where a plat shows no mapped county sewer, we ask whether the house is on septic before running a machine down the line.

Sewer Sheds and Plats the Map Does Not Show

Eight of nine plats checked fall in the county's Valrico wastewater area; Presidential Manor alone drains to Falkenburg. Nita Estates, Greenewood and Kingsway Downs, 491 parcels together, sit inside the Valrico area but show no mapped county sewer segments. Septic is possible there, and we do not service septic, so we ask before any drain cleaning work.

Lake Shore Ranch's plat point sits in FEMA zone AE at about 43 feet, while Chestnut Forest and Presidential Manor are higher and minimal-hazard. For leak work and fixture swaps near the interchange, see Brandon to the south and Thonotosassa to the north.

Seffner Plats Along the Valrico and Falkenburg Sewer Lines

County records tie each Seffner plat to a build-year range and a sewer area, which together say a lot about the lines serving a house.

• Presidential Manor — 353 homes built 1977-84, about 6.7 miles from City Hall, and the one plat here in the county's Falkenburg sewer area.
• Oak Valley — Units 1 and 2 hold 302 homes built 1979-87, in the county's Valrico sewer area.
• Oak Forest — 131 homes built 1978-81, in the Valrico sewer area, at the start of the polybutylene window.
• Lazy Lane Estates — 113 homes built 1974-77, a few years before the polybutylene window opened.
• Nita Estates — 95 homes built 1974-76; the county sewer map shows an area but no mapped gravity lines, so confirm sewer or septic by address.
• Greenewood — 156 homes with a core built 1965-78 and no mapped county gravity sewer lines, so ask how the house is connected.
• Kingsway Downs — Units 1-3 hold 240 homes built 1974-86, also showing no mapped county gravity lines.
• Lake Shore Ranch — 261 homes built 1999-2001; the plat point is in a FEMA Zone AE flood area at about 43 feet.
• Chestnut Forest — 85 homes built 2003-05, in Zone X at about 52 feet, newer than the polybutylene era.

I-4, US-92 and Kingsway: Reference Points for Seffner Addresses

Seffner is compact, so two interstates, two state roads and a few public buildings place nearly every address.

• Interstate 4 and I-75 at exit 261 — The interchange at Seffner's northern edge; Fowler Avenue meets I-75 farther north at exit 265.
• Dr. Martin Luther King Jr. Blvd (SR 574) — Forms Seffner's southern edge and meets I-75 at exit 260.
• US-92 (SR 600) — A principal arterial across the northern part of Seffner, passing Armwood High School.
• Kingsway Road — A north-south collector that holds the Seffner-Mango library at 410 N Kingsway Rd and Burnett Middle School.
• Parsons Avenue — A north-south minor arterial on the west side of town.
• Lenna Avenue — The old main street of Seffner, as noted in county road and community records.
• Armwood High School — At 12000 US Hwy 92; the school opened in August 1984.
• Rodney Colson Park — A county park at 770 Gerard Ave, one of Seffner's public recreation areas.
• Lake Weeks — A 57.73-acre lake on the southeast side of Seffner, noted in the community's Wikipedia entry.

Seffner Sewer Sheds, Polybutylene-Era Counts and Owner Tenure

Seffner has no city utility, so these figures come from county service maps, county water reports and the Census.

• Presidential Manor's 353 parcels sit in the county's Falkenburg sewer area, while the other eight plats checked sit in Valrico's. A sewer-side question for this plat goes to a different county sewer area than its neighbors, which helps separate a private clog from a main issue.
• Presidential Manor, Oak Valley and Oak Forest total 786 parcels built between 1977 and 1987. That overlaps the polybutylene period of early 1978 through July 1995, so the pipe material is worth confirming on a leak or repipe call; polybutylene is only present where it was installed.
• Nita Estates, Greenewood and Kingsway Downs total 491 parcels that sit in the Valrico sewer area but show no mapped county gravity lines. Some may be on septic or private lines; septic work is outside what we do, so we ask how the house is connected.
• Lake Shore Ranch's plat point is in FEMA Zone AE at about 43 feet, while Chestnut Forest and Presidential Manor are in Zone X at 52 to 61 feet. Low pockets matter for water heater placement and for replacing fixtures after storms, so elevation is worth checking by address.
• 1,240 of Seffner's 2,536 owner households (48.9%) moved in before 2010, and the median home value is $344,100. Long tenure suggests original-era water heaters, angle stops and supply lines in the 1970s and 1980s plats.
• County South-Central water in Seffner averages 3.8 ppm chloramine and includes a corrosion inhibitor. Chloramine tends to age rubber flappers and seals, a reason to refresh those parts on repair visits.
