Whether you’re a seasoned DIYer or just starting your home maintenance journey, plumbing can be deceptively tricky. At first glance, clearing clogs, tightening the occasional fitting, or replacing a pipe is simple. But without the experience and knowledge of a seasoned company like Expert Plumbing & Water Heaters, Inc., it’s easy to make plumbing mistakes that quickly spiral into costly damage.
Before you grab your wrench, let’s look at some of the most frequent slip-ups homeowners make when handling their own plumbing, and more importantly, how you can sidestep them.
Ignoring Shut-Off Valves
Not turning off the water supply before you do any plumbing work is one of the most classic plumbing mistakes. Ignoring the shut-off valve before doing something as simple as fixing a small leak can cause a geyser and a colossal mess.
If you plan to do anything with your home’s water system, turn off the supply first. If you’re unsure where the main shut-off valve is, ask a professional plumber. This tiny step can save you from a major mess and a bigger repair bill.
Over-Tightening Fittings
When connecting pipes or fixtures, your instinct will naturally be to make the connection as tight as possible. After all, you don’t want it to leak.
However, over-tightening fittings, especially brass or galvanized pipes, can cause leaks because overdoing it can crack the fitting or strip the threads. When tightening connections, it’s better to go for snug and use thread tape when necessary. Water pressure will also do a lot of the work to seal the connection, so if you’re really cranking it, you’ve likely gone too far.
Mismatched Pipe Materials
If you’re replacing old pipes, it’s important to match the new pipes to the existing ones. Mixing materials, like copper with galvanized steel, is a recipe for corrosion, because different pipe materials can have chemical reactions when connected directly. These reactions can lead to rust, leaks, and even pipe failure.
To avoid trouble, stick to compatible materials if you’re replacing sections. If you’re unsure, bring a photo to the hardware store, or call in a pro to identify what you have.
Incorrect Pipe Slope
Another common plumbing mistake when installing new pipes is not using the correct slope. Your plumbing system relies on gravity to keep things moving. If the pipes don’t have enough of an angle, waste can accumulate inside them. At the same time, if there’s too much slope, the water will move faster than solids, also causing a blockage.
The golden rule for drain pipe slope is about a quarter inch per foot. That gives you enough drop to keep everything moving smoothly without leaving anything behind. If you don’t know how to calculate the slope or are unsure if you got it right, consult a local plumber who knows local building codes.
Poor Soldering Techniques
Many DIY plumbing mistakes start with incorrect soldering. Soldering cold joints, using too much solder, or heating the wrong part of the pipe can all lead to weak connections that cause leaks.
To avoid trouble, take time to prepare the pipes for soldering. Clean your pipe ends with sandpaper or a wire brush, use a good flux, and heat the fitting, not the solder. If you’ve never used a torch or worked on soldered plumbing before, consider calling a licensed plumber who knows the proper techniques.
Neglecting Drain Maintenance
Ignoring your drains is one of the biggest plumbing mistakes homeowners can make. Drains can clog and back up without regular cleanings and inspections, causing a big mess and expensive repairs.
Annual drain cleaning ensures your pipes can carry water and waste away from your home and stay in good condition. Having a professional inspect the drains also reduces the risk of improper venting, which can also cause blockages and sewer problems. If the vents aren’t up to code or blocked, the drains won’t have the air they need to work correctly.
