What, How, Why – Everything You Ever Wanted to Know About Drinking Water Quality


Whether the water comes from the municipal water supply or from the well, you want it to be clear, clean and also good tasting. But that is not always a case. So what you do in addition to it is to stock up some bottled water in your home or spend a couple of more dollars to invest in a state-of-the-art water purification system. In the latter case, it will cost you to procure the filtration system, install it and to keep it properly maintained.

Once you buy your water filtration system, you can decide to save some money off the installation costs. All you need to do is learn how to install a whole house water filter DIY and you’re good to go.

Here is how to install a whole house water filter for a household.

Locate the cold water main for a plumbing system.

If you’re having city water, cold water main requires to typically be piped with water meter which is attached and emerges from a basement floor. If you’re having the well water, this can be a supply line that comes from the well. With the well systems, there is a need of the reservoir and pressure tank which is attached closely following a good supply line.

After you have located cold water mains, you need to find the main close valve and shut off valve. If you’re having the ball valve, closed position normally indicated by the lever position which is with supply pipe. If the valve is the gate style valve and the handwheel, you can turn the handwheel totally to the right side until it stops, closing the valve.

Plan the placement of the filter housing and then mount the bracket

When you consider an eventual location of a water filter and the mounting bracket, you can choose the spot which allows access for the filter cartridge modification and provides sufficient space for the house wrench.

Mark water main pipe which you will cut

Once you have chosen the location for a filter, you can then mark the pipe you want to cut. When you are marking the pipe, ensure there is space for fitting and union which you have the plan to add a pipe. Many filter housings need the normal pipe thread (NPT) for both in and outside the house. You need to add as a minimum of one union or probably two, which will allow for the service of a filter body. Location of the unions is, actually, good place for cutting into the water pipe. To install this, you can use the union for both sides of a filter and then cut plumbing in these locations.

Create plumbing for input and the output side of a filter housing

To join into the main circuit, you can use one copper union for both an input and the output side of a filter. Using the unions will not only allow for an easy future service or the replacement of a filter unit but it will ease the job when it comes to installing new copper plumbing. Once you have the unions, you can solder (sweat) the input and the out copper sections separately. After that, you can connect them to a filter body and then install an assembled filter body using the plumbing attachments in the main line usingunions.

Start a splice plumbing by soldering one side of every union to a cut end of the main supply plumbing. Then, pick the location for a filter housing and then install a filter mounting bracket. Then measure, cut and then dry assemble short connection pieces required to connect cut input and outside of plumbing. Every connection piece can have the threaded fitting at one of its ends and the other side, the copper union.

Attach the input and the output plumbing to the filter body

Wrap threaded fittings using 12 inches of the Teflon tape before you attach. Use the care not to tighten threaded fittings in a poly filter housing because it can crack. Once plumbing attachments are being installed, connect mounting bracket to a filter housing and then temporarily connect to a water main plumbing. Then mark mounting bracket position on a wall where you need to mount the bracket. After that, you can disconnect the filter assembly.

Mount filter bracket

Use lag bolts supplied with a mounting bracket, which is generally not included with a filter body. It often needs to be purchased individually.

Connect the filter body

Reassemble filter assembly with the water main plumbing by tightening the coupling connections. When filter assembly is well connected and also tightened, you can check the position of a mounting bracket and then adjust as required. Avoid connecting filter housing to the improperly aligned bracket because this can stress the plumbing connections. If you’re satisfied with bracket alignment, you can fasten the filter housing to the mounting bracket by the use of the supplied lag bolts but don’t over tighten.

Install the filter cartridge into the filter housing.

Before you install the filter cartridge, you need to clean inside of a filter housing with warm soapy water so that it is clean to eliminate any contaminants from manufacturing. After you have set the filter cartridge, you can place an o-ring in the groove of the filter base. You need to complete this step before you have completed installing the filter assembly.

Apply the silicon lubricant to an o-ring to assist in sealing and to avoid damaging the o-ring when tightening. Select the filter cartridges based on the needs and the flow requirements. Some of the filter lists intended applications include sediment, cysts, and odor, among others. Common filter materials include synthetic fiber and polyester, among others and the filter size rating need to be in microns. The pressure drop specs and max flow rates are expected to support filter life. Many filters need to be changed after 3 to 6 months, which will depend on the use and the water quality.

Screw the filter body base into the filter body head

Align the threads of the body with the head and ensure the body is well threaded into a filter head before you tighten it. Once the hand is tight, you can use a supplied base wrench for tightening the additional of 1/4 to 1/2 turns where you don’t need to over tighten because you can tear off the o-ring seal.

Turn on the water supply and then check for leaks

Once the water supply is turned on, concisely depress the red bleed valve top of the filter head so as to bleed any of the trapped air. After that, you can check the leaks and the repair. Brass couplings may be challenging to seal and can require additional tightening. The flush system can take 5 to 10 minutes and then you can enjoy the clean water. You need to remember to change the filter regularly.

The best thing is that once you follow this process, to install a whole water house water filter will become very easy. This is actually the fundamental process and if you want to install it around your house, the entire setup will not take more than 2 to 4 hours.
