What Is a Strainer in Plumbing?

A strainer is a plumbing device used to remove particles from pipes. A strainer may be made of metal, plastic, or a combination of both. Its purpose is to prevent water from entering the drain, but it is also useful to remove debris. Whether you use a plastic or metal strainer, you must make sure the two parts are sized correctly to prevent leaks. If you choose a plastic strainer, be sure to check the flange for proper alignment. what is a strainer in plumbing

A strainer is necessary in many plumbing systems because it prevents plastic or paper from entering the pipes. It can also catch jewelry before it reaches the piping. Its small holes also prevent bacterial growth, which could cause drain odors and damage the outgoing water quality. The purpose of a strainer is to protect pipes from bacteria, which can lead to a variety of issues, including the resulting leak.

If the pipe flow is downward, then a Y type strainer is the best option. It is also more efficient if recurrent maintenance is not an issue. Y-type strainers have two holes and a diagonal drain pipe where trash can be deposited. Y-strainers can also be installed vertically or horizontally. The Y-type strainer is usually installed in parallel or perpendicular positions.

Strainers are made of several materials. The most common material is wire mesh. Y strainers are used in gas, liquid, and pressurized lines. Y strainers are intended for applications where small amounts of solid particulate matter are present and clean-out is infrequent. They also feature a blow-down valve on the drain port, which allows for easy cleaning without having to remove the screen and interrupt the flow of the process.

The right size for your strainer is very important. When choosing a strainer, you must first consider the amount of debris that it will hold, and then look for the mesh size that will hold the particles. The finer the mesh, the more strain it can handle, while larger mesh can prevent excessive leakage. If you don’t have the information you need to make an informed choice, then you can read some online pressure drop charts and choose the appropriate strainer for the job.

Before installing a strainer, check the machined surfaces on the device and make sure that there are no foreign objects. When using a Y strainer, remove the plug at the end of the filter leg. Empty the collected material, clean the filter and replace the strainer. While there are no universal sizes for strainers, you must take the time to understand your requirements before buying a strainer.

When you install a strainer, remember that you should always depressurize it first. If it is plugged, you risk damaging the equipment or causing further damage. Then, make sure to install the strainer near the sensitive equipment. If you have a faulty strainer, you may have to face untimely shutdown of your equipment. Therefore, you must ensure that the strainer is installed near the sensitive equipment so that the flow rate will not be too high.
