Things to Consider Before Buying a Whole House Water Filters

Whole house water filters come in many different forms, and they are from different companies. They almost work using the same principle, but their performance and effectiveness differ significantly. Therefore, you need the right filter which will serve its purpose of eliminating all the contaminants from your water.

However, based on the number of whole house filters available, it’s not easy deciding which filter you should buy. The market is full of different types of whole house water filters. These devices range from simple water filters to advanced devices that use membranes for water purification. On this note, I sampled the most critical things that you need to consider when selecting your whole house water filter. These things are essential, and if you follow them, you will end up choosing a water filter which will serve you satisfactorily.

Planning on buying a whole house water filter, consider the following;

Your Water Flow Rate

A flow rate is a number of gallons flowing through your system within a minute. It dictates the amount of water available in your system. You need to know the amount of water flowing in your system so as to decide on what system to buy. Commonly, your water flow rate for your home may range from 12 gallons per minute (GPM) to 40 gallons per minute (GPM). Regarding this, a water filter with a capacity of less than ten GPM is, therefore, improper as it will not ensure an uninterrupted flow of water. Also, it will interfere with the water pressure and cause a huge loss regarding water, time and money.

The Filter Life

Whole house water filters have different filters. Sediment filters lifespan depends on the quality and quantity of water.  On the other hand, carbon filters can serve up to 150 000 GPM in its whole life. Moreover, if the filters have a sustained backwash cycle and a backwash valve, they can last much longer. Make sure you know depending on the quality and quantity of your water you know what type of filters you need.

The filter size

Filter size determines the number of activities. First of all, a large filter will offer a quality service for long. Also, it gives room for more water to flow through the system with great pressure. The amount of water you use per day will determine the water filter size you will select. If you make a mistake and just select any water filter, you might end up having less water than needed or more than needed.

Port size

In most cases, a whole house water filter has a port house of about one inch. Even if your water system at home has a ¾ inches piping system, fitting it into the one-inch port is easy. A whole house filter with one-inch port carry’s enough water that ensures no pressure drops even when the pipe diameters are interchanged.

Contaminants in the water

It is of great importance to know the different impurities in your water before buying a filter system. This helps you in determining the components required for the filtration. The various contaminants are determined by taking a sample of your water.

How to Install a Whole House Water Filter

The process of installing a house water filter requires tools like a drill, drill bits, adjustable wrenches, tubing cutter, bucket and the whole house water filter.

Stage 1: Choose a suitable location to fit the filter. This location should be accessed with ease while changing the filters.

Stage 2: draining the entire system

First, stop any water flow to the house. Then cut enough section of the pipe that accommodates the filter, connection fittings and put the new shut off valve.

Stage 3: measuring and cutting the pipes

Assemble the system’s parts and mark for cutting. Hold the pipe in place to cut exact position for fitting the shutoff valve.

Stage 4: Attaching the fittings

There is push fitting on the side of your filter which you need to connect to the pipe at its furthest end. In case the filter fitting does not match the diameter of your pipe, you can use an adapter on both sides to fit it in. It is recommended that you tighten the fittings. You can use a Teflon tape which offers a good seal between the fittings and the filter port. After all the fittings are in place, make a mark on the final piece of the pipe you are using by aligning it with the edges of the shut-off valve.

Stage 5: Positioning of the Filter

During the filter installation, ensure that water enters it through the port marked “in” and leaves through the port marked “out”. Be careful and know that in case the fittings are matched wrongly, the system will not work properly.

Stage 6: Testing the system

The entire kit comes with a handle that turns the inlet valves in various positions. If you fix the filter correctly, turn the valve in off position and slowly turn the water on at the shutoff valve. Any leaks in the system should be identified at this level. You should use the handle again to switch the valve from off to filter position for the tank to fill with water. Check for any leaks again. If any leaks are detected, you should tighten the fittings until leaking stops.
