Hose End Sprayers Not Siphoning (Reasons and Solutions)

It’s better to inspect all of your garden sprayer heads at the start of the gardening season. They occasionally fail to switch on or off. Even the most reputable and well-known sprayer brands can have problems. 

A little elbow grease and some precautionary steps can sometimes cure the issue. But before you jump to any conclusion, you need to know the reasons why it happens. So you can fix the problem.

1. Sprayer Trigger Clogged 

Any silt or mineral deposits that are causing the problem may be extracted using this combination.

Solution 

If your sprayer trigger is jammed, try this easy repair. Fill a bucket halfway with vinegar and the other half with warm water. Soak the spray gun in the solution for 30 to 40 minutes before trying to spray again. 

2. Spray Gun Leaking

It’s possible that a faulty connection is causing a spray gun to leak. The O ring may also require lubrication or may just be worn out. 

Solution

Make sure you’re using the right hose end connection. If there’s a problem with the O ring, either oil it or replace it.

If you’re replacing it, take a look at our suggestions for o rings-

3. Sprayer’s Filtration System

It’s also possible that the issue is with the sprayer’s filtration system. This filter is meant to prevent blockages. 

Solution

However, when it becomes clogged, the pressure drops or stops entirely. You might be able to clean the filter by flushing it out. It may need to be removed and cleaned or replaced if this is not the case. 

Also if you need to replace the filtration system, here’s our recommendation- 

4. Pump Impellers Pressure

Pump impellers are responsible for building pressure within the pumps. If it fails, the pressure might be influenced. 

Solution

The pump may need to be disconnected and cleaned. This is a more difficult task. To avoid damage, always follow the manufacturer’s recommendations for this type of repair.

Prevention of Hose End Sprayer Not Siphoning 

These garden sprayers offer a more consistent spray pattern and may save you a lot of time when it comes to cleaning. Just remember to store your lawn sprayer correctly while not in use. And follow the precautionary measures to avoid such issues.

1. Use No-clog Sprayer

If you get a no-clog sprayer, you may prevent a lot of lawn sprayer issues. These are manufactured with clog-resistant filters and nozzles. 

Even if the liquid within is recirculated or contains particles, no-clog sprayers operate properly. It’s important to operate it at the proper angle.

If the blockage is significant, you may need to remove the entire sprayer from the bottle. Also, soak the sprayer in vinegar or alcohol.

2. Keep the Nozzle Clean 

Clean the nozzle on a regular basis if your sprayer contains oil. The same applies if any other substance that hardens, like hairspray. Before doing so, remove the nozzle cap by twisting it a quarter-turn counterclockwise. And then attempt spraying it again. Your sprayer may now function if the nozzle was too tight.

If not, unscrew and remove the cap, then soak it in hot water or vinegar. Then poke a hole in any obstruction in the nozzle itself with a pin. Soak the nozzle with alcohol if your bottle includes hairspray. 

3. Keep the Plastic Tube and Piston in Place

The sprayer’s plastic tube is supposed to expand entirely to the bottom of the bottle. However, it often coils up and the liquid comes through when the level is at the bottom.

A one-foot length of 1/8-inch plastic tubing from a hardware shop can steer clear of this.

Again, when you pump the piston, it might not retract. The most common reason is a damaged or missing spring. But the spring can also just pop out of place.

The spring isn’t always accessible. If it is, a replacement may typically be found at a hardware shop.

You may be able to enhance the sprayer’s function by pouring vegetable oil through it. That’s when the seals break down and the trigger work. However, the sprayer only supplies a small amount of liquid. 

With that, we’re at the end of our discussion. Now you know how you can deal with hose-end sprayer issues.
