Do I need a bypass for my water filter?

Author: Gerda Carroll  |  Last update: Wednesday, April 16, 2025

When installing a point of entry (POE) filter, also referred to as a whole house water filter, it is typically installed near where the main supply line enters the property, before the pipes divert around the house. Plumbing in a filter bypass is strongly recommended.

What happens without a water filter bypass plug?

The water system won't function if the water filter or bypass plug isn't installed. However, some refrigerators don't need a bypass plug. They still have water filters installed, but the bypass system works a little differently. The filters on these models include a cap that should be installed in place of the filter.

What is the purpose of a bypass on a filter?

All engine oil filters or heads are equipped with a bypass valve. This valve is needed so the engine does not become starved of oil as the filter clogs with debris.

What does a water filter bypass plug do?

Many refrigerators have built-in water filtration that filters sediment and contaminants from the water going to the dispenser and/or the icemaker. If you do not need or want to use the water filter, a bypass plug must be used in place of the filter.

Does my fridge need a filter bypass?

If you don't need the built-in water filter of your refrigerator that filters out sediments and contaminants from the water supply, remove it and use the bypass plug instead. Remember that the water will not run when called for if a bypass plug is not present and the system is left filterless.

Bypassing EcoWater Softeners/Filters. Bypass model 2.

Do you need a bypass for water filter?

You should put a bypass on every unit that has a drain line attached to it. Such as an iron filter and a water softener. You would want a bypass on EACH one.

What are the disadvantages of the bypass filter?

The two-in-one design significantly increases restriction, causing shorter filter life and decreased cold flow performance. Poor cold flow performance may result in by-pass valves remaining open for longer, depriving the engine of clean oil during start-up and leaving the engine temporarily unprotected.

Will a fridge work without a water filter?

With the filter removed, the water system will continue to operate, bypassing the filter, and the clogged filter will not cause slow water dispensing or low ice production. However, you will need to install a new filter to have filtered water. REMINDER: Make sure you flush the system after replacing your water filter.

What does a water bypass do?

Typically a 3-way bypass diverts water from the outlet of a pump back to the reservoir. If your water softener or UV disinfection system has a 3-way bypass in place, you can temporarily turn your unit “off” without disrupting the flow of water into your home.

What is the function of bypass filter?

A bypass filter, also known as a pressure relief valve, is a very important part of an oil filter. When oil is too thick or the filter is clogged, the valve opens. If the valve doesn't open then the filter may eventually burst. Bypass filters are designed to remove fine organic and inorganic particles.

Why do you need a bypass valve?

The primary function of a bypass valve is to redirect flow around a particular component or section of the system. This is useful in applications where continuous flow is needed while allowing a portion of the fluid to bypass a specific area (such as a filter or heat exchanger) when it is not in use or needs servicing.

What is the purpose of the bypass function?

A bypass is like a detour for your blood to use to get around an obstacle. Creating that bypass involves taking a blood vessel from somewhere else in your body, such as your leg, arm or chest, and using it to craft the detour around the blockage.

Do you really need a refrigerator water filter?

The short answer is that fridge water filters do work for some simple needs — mainly those related to chlorine, like unpleasant tastes and odors. However, the list of things a refrigerator filter can't do is far longer. For example, fridge systems won't reduce contaminants like arsenic, pharmaceuticals and fluoride.

Why is my fridge not dispensing water after replacing the filter but?

Air may be trapped in the water system after replacing the filter. Press the dispenser cradle for at least 5 minutes to purge any air from the water lines.

What is the purpose of the bypass valve in the filter?

An oil filter's bypass valve is a safety measure when the oil filter becomes clogged, or the oil is too thick. It's also known as a pressure relief valve. Basically, when oil can no longer pass through the filtration medium, the bypass valve opens to allow the oil to flow directly to the engine.

What does bypass mean on a water filter?

A bypass in connection with water basically means that a certain section of a pipe is bypassed. In the specific case of the bypass valve, it is possible to "bypass" the connected water treatment system. This can be advantageous, for example, if the device is defective or needs to be replaced.

What is the purpose of the bypass hose?

The bypass hose allows coolant to recirculate within the engine, without passing through the radiator, as it does when the engine is warmed up and the thermostat opens. The bypass hose connects the thermostat housing and the water pump.

Do all water softeners have a bypass?

Most home softeners will have either a “Push to Bypass” valve or a “Turn to Bypass” valve.

Will my ice maker work without a water filter?

The short answer is not necessarily.

An ice machine will operate without a filter, but will quickly start having problems will scale buildup, especially in a city where the water is considered “hard”.

Can you bypass the filter on a refrigerator?

They are designed so that the lack of a filter doesn't mean you cannot have water. That is how my two work. Some have a “bypass plug”. If you don't have that you can order.

Why does my refrigerator need a water filter?

A refrigerator water filter cleans tap water by trapping and neutralizing contaminants before it flows through the fridge dispenser and ice maker. The porous material of the activated carbon in the filter reduces impurities by absorbing contaminants.

What is the purpose of a bypass filter?

Advantages of Bypass Oil Filtration

This results in longer oil change intervals and lower overall maintenance costs. Improved Engine Protection and Reliability: By eliminating abrasive particles, bypass oil filters protect engine components, enhancing reliability and reducing likelihood of unexpected maintenance needs.

Is a bypass filter system better than a full flow system?

Bypass oil filters provide better filtration efficiencies. Engine makers recognize the benefits of bypass filtration. Bypass oil filters are used in addition to, and not instead of, full-flow filters. Bypass filters will not alter or void any engine warranty.

What is a low bypass filter?

A low-pass filter (LPF) is a circuit that only passes signals below its cutoff frequency while attenuating all signals above it. It is the complement of a high-pass filter, which only passes signals above its cutoff frequency and attenuates all signals below it.
