Inside the World of Plumbing Professionals


Plumbers install, repair, and maintain the pipes and fixtures that provide water, gas, and waste disposal in residential and commercial settings. They also inspect plumbing systems to ensure compliance with building codes and regulations.

Becoming a plumber requires extensive training, either through a union or trade school apprenticeship or a college program. It’s a challenging and rewarding career that offers job security and substantial financial rewards. Visit Website to learn more.

1. Check the Washer

A puddle underneath your washer is never a good thing, and it can indicate serious problems with your appliance. Before you call a plumber, check your owner’s manual and online resources to see if your washer can be fixed with a simple repair, like replacing a knob or cleaning a filter.

Leaking can also occur during the fill or agitation cycle because of a damaged tub seal or water level switch. To fix this, reduce the size of your laundry load or run a small test cycle to see if the problem persists. If it does, you’ll need to replace the water level switch. To do this, you’ll need to remove the access panel and disconnect your washer from a power source and water supply. You’ll also want to shut off the gas line if your washer is connected to one.

2. Check the O-Rings

O-rings are designed to hold pressure, but if they’re subjected to too much stress they can rupture. This is called expansion rupture and occurs when trapped pressurized gas or air reaches a point of expansion that the elastomeric material can’t withstand.

To avoid this, O-rings should be installed properly. This includes cleaning the mating surfaces, ensuring the O-ring is sized correctly for a snug fit, and using a compatible lubricant during installation to prevent tearing.

Avoid pinching O-rings or rolling them down shafts, as this can distort their original shape and lead to leaks. Instead, gently place them in their grooves and slide them into place. You may also want to use a lubricant to help them slide more easily. This will not only protect the O-rings from damage, but it can also help them seal better.

4. Check the Seat

Whether it’s fixing a leaky toilet or installing a new bathtub, plumbers need to have a broad understanding of the systems they work on and be able to use a wide range of tools. They also need to be able to solve problems quickly and efficiently.

When a plumber is working in sewage systems, they may be exposed to bacteria and other microbes. These can cause infections like cholera, typhoid, hepatitis, and polio. To avoid this, the plumber should wear rubber gloves and masks when handling sewage-related materials. They should also inspect their equipment regularly and follow all safety procedures. They should also wear a helmet when working with power tools. In addition, they should lubricate the tip of the set screw to prevent it from stripping. This will help the screw grip more easily and will prevent future problems.

5. Check the Set Screw

Unlike bolts that use threading to hold components together, set screws have a point that locks into a mating hole or slot and exerts compressional force. The result is a tight grip that holds parts securely without damaging the surrounding surface.

If you suspect a set screw is stripped, try applying Kroil or another penetrating oil to the threads and tapping it lightly with a hammer to knock the screw loose. You can also use a larger wrench or Allen key to grip the set screw and twist counterclockwise. A specialized tool called a screw extractor can also help remove stuck or stripped set screws. Just be sure to use a wrench or Allen key that is a suitable size for the threads and not too large to damage the fixture.

6. Check the Water Line

Water is a necessity for all of us, but it can quickly become the enemy if it leaks into places where it shouldn’t. This can damage your walls and floors, ruin furniture, and pollute the ground and surrounding environment.

Leaks in underground water lines are often difficult to find, but a plumber can use a number of different methods to locate them. One simple method is to listen for the sound of a running water line. You can also check the ground and surrounding areas for damp spots, which may indicate a leaking water line. Another option is to check the water meter. If the numbers on the meter are moving, there is a leak in the water service line. Shut off the water and then listen to the meter again. If the sound stops, there is an internal problem like a running toilet or a leak in your house plumbing.

7. Replace the Washer

If the washer is worn or damaged, it may not be sealing the valve seat properly. In this case, the washer needs to be replaced. You can usually find a replacement washer at your local hardware store. Just make sure that you buy one that is an exact match for your old washer.

To replace the washer, first you will need to isolate the water supply by turning off the water at the valve underneath your sink. Then, remove the faucet cover by using a screwdriver or wrench. Once you have removed the cover, remove the stem nut and then unscrew the brass screw holding the washer in place.

Next, look at the faucet valve seat. If it is rounded or has a square or hexagonal hole through it with no slots, then you will need to dress the seat with a faucet seat dressing tool.

8. Replace the O-Ring

If the o-rings are cracked it is time to replace them. O-rings can break down over time due to age and exposure to abrasive materials. This can cause them to fail and result in leaks.

An o-ring is an elastomer-based seal that sits in a groove on a component and is compressed between two surfaces when the components are joined together. This compression creates a seal that is both inexpensive and reliable.

To replace an o-ring, remove the old one from its groove and clean the groove to ensure that it is free of debris and previous sealant residue. Before inserting the new o-ring, make sure that it is the correct size and material for the application. It should also be lubricated to ensure that it slides into the groove without twisting or damage (see article on o-ring selection).

10. Replace the Seat

A plumber’s job duties include installing and repairing plumbing systems in residential and commercial buildings. They work with a wide range of tools and materials, and must be familiar with a variety of building regulations. Plumbers also must be able to troubleshoot problems and find effective solutions. For example, if the toilet seat is loose or not sealing properly, they can spray the seat with WD-40 to lubricate it and then use a wrench to tighten it. Before replacing the seat, they should wear rubber cleaning gloves and thoroughly clean the toilet and surrounding area. This prevents the buildup of harmful bacteria.
