How To Install Water Doctor Membrane Filter?

A water doctor membrane filter is a filtration system that uses a thin membrane to remove contaminants from water. The membrane works by trapping particles, such as dirt and debris while allowing only pure water molecules to pass through it. This filtering process helps reduce chemicals and other pollutants in the water supply. Once installed, the membrane filter will improve the quality and taste of your water, making it much safer for drinking, cooking, and washing.

Necessary Installation Tools

  •     Variable speed driller
  •     Teflon tape
  •     small knife
  •     Screwdriver

How To Install Water Doctor Membrane Filter?

Drill the faucet hole: You will need to drill a hole, preferably in the center of your kitchen or bathroom sink, large enough for your membrane filter system’s external faucet.

Shut off the water supply:  Turn off the water supply and open the faucet to relieve any pressure.

Mount the tank ball valve: Once the hole is drilled, attach the main tank ball valve in place. Use a wrench to ensure that it is secure and tight.

Install the drain clamp: Connect the drain clamp to the drain pipe. It is important to remember that the clamp should be tightened firmly for it to work correctly.

 Check for leaks: Once everything is in place, turn on the water supply and inspect for leaks. If there are any, shut off the water supply and tighten connections if necessary.

 Mount the filters and membrane: Once the water supply is on and all connections are tightened, mount the filters and membrane. Take care to ensure that they are correctly secured in place.

Connect the tubes: Connect the tubing from the filters and membrane to the tank ball valve. Ensure all connections are secure before turning on the water supply again.

 Hook-up ice maker: If you have an ice maker, connect the tubing to the inlet side of the membrane filter. This will ensure that your ice is clean and pure.

 Activate the system: Once everything is in place, turn on the water supply and activate your membrane filter system. Enjoy clean and pure water.

Replacing The Water Doctor Membrane Water Filter?

Step1: Shut off the water supply and turn off all faucets connected to the system.

Step 2: Unscrew the old filter from its housing, taking care not to break any parts in the process.

Step 3: Remove any debris or dirt that has built up inside the housing while it is in use.

Step 4: Insert the new filter into the housing, ensuring it is positioned correctly and seated firmly.

Step 5: Secure the filter using the screws that came with it and make sure they are tight.

Step 6: Turn on the water supply to fill up the system and test for leaks.

Step 7: Run some water through the faucets connected to the system, ensuring no drop in water pressure.

Step 8: Check the filter  to ensure it performs correctly and that all debris has been removed from the system.


Not enough water:  

  • Check the membrane housing for debris, scale, or damage. Clean/replace as necessary.
  • Check the permeate pump to ensure it is running correctly and that the pressure differential gauge indicates a minimum of 10 psi.
  • Examine the flow restrictor to verify the proper flow rate.

Under the sink is wet: If the under-sink area at your installation location is wet, you may need to locate a dry spot to work in. If water leaks onto the floor, mop it with a damp cloth and then use a towel or shop vacuum to dry off the surface. Once the area is dry, you can install the water doctor membrane filter.

Water has an offensive odor: If there is an offensive odor to the water, it could be caused by several things. To install the Water Doctor membrane filter, you must determine the cause of the smell before starting. Potential causes may include bacteria, sediment, chemicals, and other contaminants in your water supply. After identifying the source of the smell, you can determine if a membrane filter is the best solution to handle it.

Low water pressure: Sometimes, you may experience low water pressure even after installing the Water Doctor membrane filter. This can be due to various reasons, such as clogged inlet screens or filters, broken pipes, leaking connections, etc. Inspect all parts of your water system for any issues that could cause this problem and fix them if possible. If not, you may need to contact a professional for help.


Where do you put the remineralization filter?

The remineralization filter should be installed before the membrane filter. This allows any removed minerals to be added back, restoring the water’s original taste and odor.

How long does it take to run water after changing the RO filter?

Once the new membrane filter has been installed, it is recommended to run at least ten gallons of water through the system before consumption. This will help flush out any debris or contaminants left in the system after installation.

Can I install an RO purifier for tap water?

Yes, installing an RO purifier for tap water is possible. An RO (Reverse Osmosis) purifier is a type of membrane filter that passes water through a semi-permeable membrane to remove contaminants and impurities such as lead, chlorine, bacteria, and other dissolved solids.

Why is my water purifier releasing warm water?

The most common reason warm water is released from a water purifier is that the reservoir tank has become too hot. This can happen if the system hasn’t been used for long or has become overheated due to running continuously. If your water purifier releases too much warm water, it is recommended to turn it off and allow the reservoir tank to cool down.

How can I get stuck whole house water filter off?

If the filter is stuck, you’ll need to turn off the water supply to your house before attempting to remove it. To do this, go to the main shut-off valve and rotate it clockwise until it doesn’t close any further. Once the water supply is off, use a pair of pliers or an adjustable wrench to loosen the filter from the housing.

What is a living water filter membrane?

A living water filter membrane is a particular type of filtration system that uses specially-designed membranes to filter out impurities and contaminants from water. The membranes are designed with small holes that trap particles such as sediment, bacteria, algae, and other microorganisms while allowing fresh, clean drinking water to pass through into the household.


Installing a Water Doctor Membrane Filter is easy and can be done in a few simple steps. It requires minimal maintenance, so it’s affordable for homes that need clean, fresh drinking water. Additionally, the filter removes sediment and other particles, reducing harmful chemicals from the water supply. The Water Doctor Membrane Filter is an excellent choice if you’re looking for an effective way to filter your water.
