I purchased a whole house filter set and installed it, but then my flow rate dropped.
Please follow the steps below to install whole house filters correctly.
Step 1:
First, make sure that you install the filters in the correct flow direction (i.e., if your system flow is Right to Left, make sure to install the Sediment filter first, GAC or Iron Manganese second, and CTO last). Installing the filter in the opposite direction will force the water to flow from the center of the Sediment filter to the outside, causing a pressure drop and clogging your filter.
Step 2:
Second, make sure to install the GAC and Iron filter from the correct end (Center open hole on top). If you install these filters upside down, they will restrict flow, potentially damaging the filter body.
Step 3:
Third, when you install any GAC, UDF, or T33-type filters in the first stage, the filter's inlet woven surface flow will be restricted, and this woven/mesh can get clogged within a couple of hours or days, causing a significant pressure drop.

Note:
When using your filter for the first time, reduce the water flow and pressure as much as possible. This helps the filter release iron or carbon fines more effectively. High flow rates can clog the filter’s outlet fibers, causing tiny particles to get stuck in the housing head of your whole house filter system, which may reduce the water flow rate. To fix this, open the housing cover and rinse it thoroughly to remove any trapped particles. Once cleaned, securely close the housing cover. This simple maintenance step can restore your water flow rate to normal levels and ensure your filtration system continues to function efficiently. If your filter is a non-refillable type, you can use a garden hose to backflush the filter. Simply connect the hose to the filter’s outlet center port and run water through it in the opposite direction. This helps dislodge and flush out trapped particles, ensuring your filter remains effective and maintains proper water flow.
In General, The difference in the inlet and outlet pressure readings between the incoming (60 PSI) and the outlet (50 PSI) or (40 PSI) gauges on your whole house water system is normal and typically caused by the pressure drop across the system.
Here’s a detailed explanation:
Causes of Pressure Drop:
-Filters in the System:
Each filter adds resistance to the flow of water. A three-filter setup naturally results in a cumulative pressure drop, especially when the filters start accumulating debris or sediment.
The extent of the drop depends on the type of filters you’re using (e.g., sediment filters, carbon filters) and their condition.
-Flow Rate and System Demand:
When the system is in use, higher water flow rates can amplify the pressure drop because the filters must handle more water volume at once.
If you are running multiple taps or appliances simultaneously, the outlet pressure can drop further due to increased demand.
- Filter Condition:
A new filter will have minimal resistance, leading to a smaller pressure drop. Over time, as filters collect debris, sediment, or contaminants, the drop will increase.
If the pressure drop is significant (e.g., more than 15-20 PSI), it might be time to replace or clean the filters.
System Design:
The design and size of your filtration system, including pipe size, fittings, and valves, can impact how much pressure is lost between the inlet and outlet.
Troubleshooting Tips:
1- Check Filter Condition: Inspect the filters for clogs or sediment buildup. Replace them if necessary.
2- Ensure Proper Flow Rate: Verify that your system’s flow rate aligns with the filters’ specifications. If the flow rate is too high, it can exacerbate the pressure drop.
3- Inspect for Leaks: Check for leaks in the system, particularly around filter housings or connections, which could reduce outlet pressure.
4- Upgrade Filters (if needed): Consider using low-pressure-drop filters if you frequently experience a significant drop in pressure.
When to Be Concerned:
If the pressure drop increases suddenly, it could indicate an issue such as a clogged filter, a kinked hose, or a partially closed valve, or a wrong filter or filter housing.
If the outlet pressure drops below 40 PSI, this could negatively affect the performance of household appliances or fixtures, always make sure to keep the home outlet pressure to be higher than 40 PSI by adding a whole house water pump.
