Replacing old plumbing with PEX is highly recommended if you are dealing with galvanized pipes, polybutylene, or deteriorating, leak-prone copper. It is flexible, freeze-resistant, corrosion-proof, and budget-friendly. However, copper remains superior for outdoor sunlight exposure and short, rigid runs like shower valves.
Generally, you can budget around $2 to $6 per square foot for a PEX repipe. So, for a 2,000-square-foot home, you might estimate a cost between $4,000 and $12,000. You can also refine your estimate by counting your plumbing fixtures.
Despite these benefits, some insurance companies have raised concerns about PEX plumbing, particularly regarding older installations: Historical issues: There were class action lawsuits against PEX manufacturers due to premature failures at connection points, resulting in leaks and flooding in some cases.
The "135-degree rule" in plumbing states that the total (aggregate) horizontal change in direction for a drainage pipe—specifically trap arms—cannot exceed 135 degrees between the P-trap and the vent. Exceeding 135 degrees (such as using three 45-degree bends or a 90 and two 45s) requires a cleanout because sharp turns hinder flow and cause clogs.
Replacing existing, functional copper piping entirely is generally unnecessary. However, if your copper is corroding, experiencing pinhole leaks, or your home requires a whole-house repipe, transitioning to PEX (cross-linked polyethylene) is highly recommended. PEX is significantly cheaper, faster to install, and more resistant to freezing temperatures.
Leaks and Fittings Issues
PEX plumbing uses fittings and connectors that are typically made of plastic or metal. Over time, these fittings can loosen, leading to leaks. Problems can arise with crimp rings, as improper use of a crimping tool can weaken the joints.
3 Plumbing Pipe Materials You Don't Want In Your Home
Yes, a toilet and a sink can share a vent. In modern plumbing, this is most commonly done using a wet vent, where the sink’s drainpipe also acts as the vent for the toilet.
Here are the most common plumbing code violations you might not even realize you have—and why they matter.
a waste pipe must be layed so it has a fall of 1 in 4 (mcguires rule).
Did you know that PEX piping is used in about 60% of new construction projects to date? This makes it a prevalent material used in new buildings.
Avoid making guesses or unsupported statements about what caused the damage to your property. Speculating can lead to inaccuracies in the adjuster's report, potentially affecting your claim.
PMRs for malignancies of the stomach, kidney, brain, and lymphopoietic system were also elevated, especially among plumbers. Chronic rheumatic heart disease, emphysema, liver cirrhosis, and all external causes of death were the major non-cancer causes with significantly elevated PMRs.
Yes, you can repipe a house without removing drywall. Modern plumbers use flexible PEX tubing (Cross-linked Polyethylene), which can be snaked or "fished" through existing wall cavities, attics, and crawl spaces, dramatically reducing the need for wall demolition.
The lifespan of PEX pipes is one of their most appealing features. On average, PEX pipes can last anywhere from 40 to 50 years, and in some cases, even longer.
10 Things That Your Plumber Wishes You Knew
The "135-degree rule" dictates that a cleanout (an access point to clear blockages) must be installed in a horizontal drain pipe every time the cumulative turns exceed 135∘135 raised to the composed with power𝟏𝟑𝟓∘.
However, recent failures and the lawsuits that have followed those failures lead to the idea that PEX plumbing systems aren't as good as once assumed. PEX systems can fail in either the pipe or in the fitting. The most notable failure occurs when the fittings fail and water starts leaking and causing visible damage.
Pouring salt down your drain at night is a popular DIY plumbing trick used for routine maintenance. The goal is to take advantage of the salt's coarse texture and natural moisture-absorbing properties.
Many traditional Old Order Amish communities view store-bought toilet paper as an unnecessary indulgence or luxury. Instead, they rely on readily available, sustainable alternatives like crumpled-up old newspapers, mail-order catalogs, corn cobs, and cloth rags, though more progressive groups now commonly use conventional toilet paper.
For a standard 2-inch shower drain, the maximum distance allowed between the shower's P-trap and the vent is generally 5 to 6 feet depending on your local code. The exact allowable distance is calculated based on the length of the horizontal "trap arm" and is governed by your specific plumbing code.
Galvanized Pipe
Galvanized pipes are rarely used in new home construction today, but were common until the 1960s.
Keep your thermostat set to a minimum of 55°F (13°C) to keep your pipes from freezing. If you are leaving the house for an extended period, maintain this temperature to ensure heat reaches the walls where pipes are located.
It's such a simple thing, leaving a single faucet dripping, but it can prevent so many complications later on. How much value does one dripping faucet have? A lot, if it keeps your home's water pipes from bursting during frigid weather.
