Avoid brass fittings when dealing with corrosive water (e.g., well water), acidic or highly chlorinated liquids, or ammonia-based chemicals. Additionally, skip standard brass compression fittings for natural gas lines and opt for stainless steel in extreme high-pressure industrial applications.
Disadvantages of Brass Fittings
Myth 1: “Using push-fits devalues the trade.”
Some installers believe that using push-fit fittings removes the skill from plumbing, but that couldn't be further from the truth. While push-fits are quick and easy to install, the technology behind them is highly advanced.
Two of the most popular materials for plumbing fittings are copper and brass. Both are known for their durability, corrosion resistance, and versatility, making them suitable for a wide range of applications.
The standard lead-free brass fittings are made with marine-grade DZR brass and are currently acceptable under the Safe Drinking Water Act, but will be restricted to non-potable water applications as of 2014. The lead-free fittings are identified by a double groove on the face of the female fitting (see Fig.
Brass that is widely used for key manufacturing usually contains 1.5% – 2.5 % of lead [8]. Even the brass alloy manufactured with especially reduced lead content (so-called “reduced lead brass”) of American Society for Testing and Materials (ASTM) specification (B-121) has a nominal 2% lead.
Copper pipes are popular for both hot and cold water pipes because they are heat resistant, resist corrosion, and have natural anti-microbial properties. They are more expensive than plastic pipe options.
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.
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.
Vinegar acts as a highly effective, natural cleaning and polishing agent for copper. The acetic acid in vinegar reacts with copper oxide (the dark or green tarnish) to dissolve it, restoring the metal’s bright, shiny appearance.
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.
Most professional plumbers view SharkBite fittings as an excellent emergency fix or a helpful tool for hard-to-reach areas, but they generally dislike using them for permanent, whole-home plumbing. Professionals prefer traditional methods (like soldering copper or crimping PEX) for their durability and cost-effectiveness.
Pull-push rule is used for measuring the exact distances of pipe fittings and fixture in the plumbing system in doing the final lay out. It is used in measuring the length of the pipes before cutting. 5. Inside caliper is used to measure the inside diameter of a pipe.
Key Points. Brass isn't going anywhere in 2026, but unlacquered brass is replacing polished brass in popularity. Designers like unlaquered brass because it patinas nicely and adds warmth to a room. Nickel is another metal making a quiet comeback in 2026, especially in mixed metal moments.
3 Plumbing Pipe Materials You Don't Want In Your Home
Some people tighten brass fittings as much as possible, thinking this creates a secure seal. However, overtightening can distort threading, weaken connections, crack the fitting, and contribute to permanent damage.
Avoid tarnishing cookware by washing copper using warm water and dish soap. Dry it immediately after. Never put copper in the dishwasher.
As the fall rains intensify and the seasons shift, one surprising tip is getting renewed attention: pouring vinegar down your drains to help prevent clogs.
Yes, Coca-Cola does clean copper. Because it contains phosphoric acid, it can effectively dissolve tarnish and rust on copper items.
To protect your plumbing and the environment, you should never put fats, starches, harsh chemicals, or solid waste down your drains.
a waste pipe must be layed so it has a fall of 1 in 4 (mcguires rule).
Here are the most common plumbing code violations you might not even realize you have—and why they matter.
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.
The modern alternative to traditional metal and rigid pipes is called PEX (cross-linked polyethylene). It has largely replaced copper for indoor water supply lines because it is flexible, cheaper, and easier to install.
SharkBite manufactures both PEX-A and PEX-B piping. You can buy either depending on your plumbing project's needs.
