If you are looking forward to installing an under-sink water filter by yourself, you must follow our step-by-step guide that will guide you to install the under-sink effortlessly and quickly.
Installing an under-sink water filter may seem intimidating at first. However, you can rest assured that we’ll simplify it for you so that you do not face any trouble while you are tasked with fixing it one day.
Initially, it appears to be hard work, and moreover, if you have some prior experience in getting small plumbing jobs done, this could be a cakewalk for you.
You could consider the process mentioned by us only if you feel that you won’t need the help of a professional.
What would you need?
You would need basic tools and supplies to install the under-sink successfully. These supplies are easily available in any hardware store, or you can order them online.
To begin with, you would need an under-sink water filter and cartridges for the filtration system. Then, to cut plastic tubings, you would require scissors or cutters.
You would need an adjustable wrench, a drill, a bucket, and a screwdriver from your tool kit. Also, ensure that you choose the right filter for your sink to avoid any issues later on.
How to install an under-sink water filter?
These are designed to go underneath your kitchen sink. Start by installing the filter to intercept the cold water. Next, you will be required to drill a hole in the kitchen sink in case the water filtration system comes with a faucet. You can also use the existing hole from the soap dispenser.
Ensure that the cold water supply is turned off, as you don’t want your kitchen to flood with water while installing the under-sink filter.
You may have to switch off the cold switch valve. And to distinguish the cold shutoff valve from the hot shutoff valve, you need to feel the pipes they are attached to. The one which is comparatively cooler is your cold switch valve.
Now, you need to remove the tube from the faucet to let the under-sink intercept with the water line. Take a wrench and loosen the nut. Now remove the tube from the supply line.
Install the existing copper T-adapter at this point. You can use Teflon tape around the adapter threads to ensure no water leakage. You don’t want to overtighten the fit.
This is the time to connect the filter’s tubing to the T-adapter. To make the replacement of the filter cartridge easy, start by installing a shutoff valve at this tubing. You can now attach the copper insert and the nut to finally connect the fitting. Tighten it in place properly.
If your under-sink filtration system has a dedicated faucet, you need to follow this step. To ensure that there is something like a reverse osmosis system or not, you can check the user manual.
Further, depending upon the size of the faucet that comes in the contents of the box, you can drill a hole in the countertop. You can install the faucet in the hole from the soap dispenser, if not the countertop.
It is time to install the new faucet filter near the existing faucet. The extra hole you drilled is to ensure that you install a new faucet and do not end up replacing the existing one. An additional faucet will allow you to divert cold water supply in the future in case of need.
Installing the new faucet requires you to hold the tap above the countertop. After that, you can tighten the fitting underneath it, and to avoid any leakage, you must fill the space around the faucet’s gasket.
If your filter comes with a mounting bracket, you can avoid fixing it under the sink and instead mount it against the wall. Now you can drill holes but keep space for maintenance later on.
After placing the unit on the bracket, now is the time to connect the system to plumbing connections. For that, you need to ensure the inflow and outflow ports are not confused while you are at them.
The outflow line has to be connected to the faucet’s tubing and the cold water feed line to the inflow line. Water can pass via the filter from the cold water pipe to the faucet.
Finally, you can allow the water supply by turning it on. Ensure that you move the valve slowly to avoid sudden and increased water pressure as it could damage the connections. Mostly, the filter system has a shutoff valve that you can slide to let the water in the unit. To relieve trapped air, press the pressure release valve.
Do not forget to check the system for leaks, which can be the case if the system’s o-rings are not placed properly. Ensure that the fittings are tightened, or the leaks could worsen over time. You can also use Teflon tape to tighten the connections further.
Ensure that you have properly checked for leaks. Now the water will be filtered, but it is best to flush it once before using it. Allow the water to pass through the filter and clear off any dust, chemicals, or cartridges from the manufacturing.
Allow at least one bucket to pass through the filter, which can be used for other purposes like washing or watering the plants.
Remember to go through the user manual in case of any difficulty. Different filtration systems may come with unique installation processes which the manufacturer would specify.
Overall, this process will suffice, except for a few steps here and there, for which you can always seek help from the user manual.
Hope this step-by-step guide has helped you understand the process better and will assist you in installing the under-sink water filter without any trouble.
