Curious as to why your Waterpik is leaking? In most cases a leakage might just be a case of improper usage. A simple correction in how you use the water flosser will automatically correct the problem.

A second option could be product malfunction. If that’s the case you’ll need to contact the service provider for either repair or replacement.

Which applies in your case? To determine what to do next in your situation, let’s look at a few reasons why it may leak.

Water in the Reservoir

Do you empty your Waterpik completely after every flossing session? If not, that could be one of the reasons why it’s leaking.

Most Waterpiks have valves at the bottom of the water reservoirs. However, this valve is designed to hold water for only a short time while you’re flossing, not for indeterminate periods. Leaving water in the reservoir overnight will result in leaking.

A small change in how you use your appliance can solve the problem instantly.

Faulty Valve

A faulty valve will also cause leaking. This is often the case when you fill up your Waterpik with water and it immediately starts leaking. There’s not much you can do yourself—you have to get in touch with customer support for repairs.

Handle in Wrong Position

Is the handle securely attached to the candle holder? If not, water left in the hose will start leaking from the handle. Luckily this is another situation you can fix yourself. Make sure you put the handle in the correct position, in the holder with the tip facing upwards.

When how you use an appliance exactly in the way it was intended to, you often solve a problem.

Faulty Hose

A faulty hose might just be another reason why your Waterpik is leaking. If the hose is the issue then your only alternative is to get a replacement. Contact customer service and they’ll assist as necessary.


Is it worth going to all the trouble to test and fix problems? For cleaner teeth, of course it is.
