How to Remove Flow Restrictor From Shower Head : Precautions to Take

  • Before uninstalling the shower head, make sure to turn the water off. If possible, cut the supply of the entire bathroom. This will prevent a disaster if you accidentally break a pipe.
  • Make sure to take a look at the user manual before installing or uninstalling the shower head. The procedure may vary for some shower head models.
  • If the connecting nut doesn’t move, don’t apply too much force with the wrench. If you see that the thread is rusty, apply rust remover and wait 30 minutes. Then try removing the shower head. In this case you can also use silicone spray as a lubricant.
  • Be careful when using the screwdriver. Its tip could cause serious damage to the connecting nut when trying to remove the flow restrictor. Be extra careful if a shower water filter is installed.
  • If you notice any water leak after installing the shower head, apply more Teflon tape on the shower arm to solve the problem.
  • If you notice a build-up of limescale, rust or mud inside the shower arm, use a hard bristle brush to clean it. For best results, soak the shower head in vinegar overnight.


Certainly, flow restrictors are necessary in places with too much water pressure. They also help you pay less on water bills. However, in other places they aren’t necessary.

If water flow on your shower is too weak, you should verify if there’s a flow restrictor inside your shower head. If you find one, follow the tips in this article to remove it. Before you start, make sure you have all the necessary tools and materials at hand.


Q. 1: Do all shower heads have flow restrictors?

A. Not all. However, most new models do. The National Energy Act obliges all manufacturers of shower heads to install removable flow restrictors in their products. These rubber washers are designed to restrict flow to a maximum of 2.5 gal/min.
