Reduced water pressure
There are a few issues which can cause this to occur.
If the connection between the shower arm and shower filter is over tightened, the washer can dislodge inside of the shower arm, and restrict water flow.
To fix this, you need to:
- Remove the shower filter and check whether the washer is inside the shower arm.
- If it is, then remove and reseat it inside the connection on the shower filter, and then gently hand tighten the filter back onto the shower arm.
- If the washer was not inside the shower arm, then check the connection between the shower filter and shower/shower mount (bracket).
- Make sure you are only using one washer in this connection.
- If there are two, then one of them can move around and reduce the water flow.
- If the water flow coming out of the shower filter is good, then attach the shower, making sure you only use one washer in the connection between the shower filter and shower.
- Once that is connected, turn the water on again, to check the water flow. At this point, the shower should have full water pressure.
Sediment build up
If you have sediment in your water, then over time, it can build up in the filter and reduce the water flow. To fix this issue please see Water flow reduced over time (sediment)
Filter screen inside Shower Mount
If you have a shower mount or shower which has a raised filter screen in the center of the connection, it may restrict the water flow coming out of the shower filter. These filter screens can be removed by gripping the top of the filter screen with pliers and unscrewing by turning it counter-clockwise.
