Updating plumbing old house
Siebert estimates the average cost to replumb all supply lines in a home starts at about ,000, but plumbing costs can vary widely. Hope says older home repairs also can be difficult due to old-fashioned craftsmanship, such as thicker wood framing and plaster walls rather than drywall.
"They were built so much stronger than new houses, so simply drilling into wood or cutting into a wall is substantially more difficult," he says.
It's better to cut out the entire system, if possible, starting as close to the water meter as as you can.
If you're updating plumbing fixtures at the same time, you'll be able to route the new waterlines to accommodate them as efficiently as possible.
"Typically in older house plumbing repairs, time has taken its toll," Hope says.
Many local plumbers, including Hope, say old house plumbing repairs and improvements often presents challenges not found in newer houses. The problems stem from age and outdated plumbing materials such as galvanized steel water supply lines, cast-iron drain pipes and clay sewer lines.
This undermines the retrofit, because the pipes you leave will deteriorate and cause problems long before the replacements will.
It also complicates the process of replacing the pipes, because you'll need transition fittings at every joint between dissimilar materials.
If your old house has galvanized pipes, replacing them is a good idea.She hired Jack Hope of Hope Plumbing in Indianapolis, who found a secondary clay sewer line overrun with tree roots.
