Water Flosser Tip Modification to Reduce Pressure

This project is to convert a standard water flosser tip to a low-pressure tip.

A Water flosser tip that you want to convert to a low-pressure tip.

Epoxy. (Any standard epoxy)

A pin or paperclip (the thinner one will result in lower pressure. It's your choice which to use)

A small screwdriver or something similar to pack the epoxy into the tip.

A magnifying lens may also prove beneficial if needed.

In the photo, the blue tip is a low-pressure tip from the manufacturer. The clear tip is the one I'm modifying.

This project is to convert a standard water flosser tip into a low-pressure tip. This could be a Waterpik brand or any other brand with a similar tip.

Some people may find that their water flosser water pressure is too high, even on a low-pressure setting, if it has one. Or, you may want to buy a low-pressure tip but your unit don't come with one or you are unable to buy one.

You can see in the photo, the blue tip has a pressure reducing "plug" inserted. This plug has a small hole in the center to reduce the water pressure.

What you need to do is mix a small amount of epoxy per the directions on the epoxy packaging.

Fill a small portion of the tip with the epoxy as shown on the photo.

Take a pin or paperclip and insert it in the center of the epoxy in the tip. This is where it gets tricky***. The epoxy should be soft and workable for more than a few minutes. You will need to ensure the pin remains in the center, although that is not critical. BUT, you will have to remove the pin and reinsert the pin several times a minute until the epoxy sets and no longer adheres to the pin. The goal is to get the epoxy to set (harden) with a hole in the center. See photos.

You will only have one chance to get it right. Once the epoxy hardens, there's nothing more you can do. The choice of using a pin or a thicker paperclip is yours. Assuming the pin is thinner than the paperclip, the pin will make a smaller hole producing a slightly lower pressure than if the paperclip were used to make the hole.

The tip will be safe to use once the epoxy is fully hardened. It's best to let it set for 24 hours before using the tip.
