Emergency Plumber in Wilson Heights, Florence, SC: Patching an Older System or Replacing It

Homes from the 1960s to the 1980s: the pipes that came with them

Homes built across those decades did not all get the same plumbing. What a house has depends on when it was built and what has been replaced since. The table shows what is typical for each period, which is not the same as what is in a specific house.

Typical materials by build period, not specific to any one house

Period	Common supply pipe	Common drain pipe	What tends to fail
1960s	Galvanized steel or copper	Cast iron	Galvanized corrodes inside; pressure falls
1970s	Copper, some galvanized	Cast iron, early plastic	Copper joints and old valves
Late 1970s to 1980s	Copper; polybutylene in some homes	Cast iron or PVC	Polybutylene fittings, if present
After a past repair	Whatever the plumber used then	Mixed	The joint between old and new

Polybutylene is a gray or blue flexible plastic supply pipe that was used in some homes from the late 1970s into the 1990s, and it is known for failing at its fittings. If you can see gray flexible pipe under a sink or at the water heater, have it looked at before it leaks.

Seventy-six percent owner-occupied: repair or replace when you plan to stay

About 76 percent of Wilson Heights homes are owner-occupied. An owner who stays has a different calculation from a landlord or a seller, because the benefit of ending a cycle of repairs accrues to the person living there.

Each repair carries its own cost and the cost of the wall, ceiling or floor opened to reach it. The second and third often cost more in finish work than in plumbing. Where the pattern says four or five more, replacing the system usually costs less in total.

• Count the leaks on the same system in the last three years
• Add up what each repair cost including the patched wall or floor
• Note whether pressure has fallen across the whole house
• Check whether any supply pipe is gray flexible plastic
• Ask for the repair quote and the replacement quote together

Wilson Heights: same-era homes age the same way

Wilson Heights covers roughly 0.44 square miles, and homes built in the same years by the same builders tend to age in the same way. What failed next door is a fair preview of what may fail at your address.

That is useful rather than alarming. Ask neighbors what went wrong and when, and compare it with your own record. A cluster of the same failure on the same street is a pattern worth acting on before it reaches you.

• Replacing a whole system rather than patching it
• Finding a leak without opening walls
• Old drains that keep slowing
• A tank that has reached the end of its life

Cast iron drains at forty or fifty years: slow, not broken

Many homes from these decades have cast iron drain lines, and cast iron lasts a long time. What changes with age is the inside of the pipe, where scale builds up and the bore narrows, so drains slow long before anything actually breaks.

That matters because a slow drain in an older house invites a chemical cleaner, and caustic products attack older pipe. A camera shows whether the line is scaled, cracked or simply coated, and the answer decides between cleaning it and replacing a section.

A repipe in a home you live in: what the work involves

A repipe is permitted work in Florence County through the Building Inspection Department on (843) 676-8600, with rough-in and final inspections. The new lines are run alongside the old where possible, so most homes keep water for most of the work.

Single-storey homes on a crawl space are the most straightforward case, because most of the work happens underneath. Slab-on-grade houses usually mean routing overhead through the attic. The repiping page has the full sequence.

Not every house needs all of it. Where failures are confined to one run, replacing that run is proportionate and far less disruptive than opening every wall.
