Ever got a spray bottle where you have to keep pumping the trigger to get it to finally spray? Here is how I solved this nuisance on one of my bottles.

Step 1: Remove the Spray Head.

A quick unscrew and the head comes off.

Step 2: The Nifty Check Valve!

Check valves are very handy in many applications from fuel pumps to aquarium air pumps. In fact this is a spare check valve from an aquarium air pump!

Step 3: Adding the Valve.

Provided the suction straw is the right inner diameter, the valve will fit on easily. The valve will have an arrow or label for the output or discharge. It is this side that goes into the straw. Now with the valve fitted, I screwed back on the head.

Step 4: Completion and Enjoyment!

Now once the trigger is pumped a few times to prime the suction straw, the spray bottle is ready for action anytime! No more have to pump pump pump to get the spray bottle to deliver it's cargo!

I hope you found this useful!
<p>if you cut the suction straw just beneath the head and add a flexible hose (like aqaurium tubing) it will allow it to move around the bottom of the bottle also so even if you only have a little left in the bottle you can still use it, or if you are tilting the bottle it will stay with the fluid</p>
<p>It will work better with some weight near the end of the hose. Try sole solder wrapped around the end,tight but not too tight as to be a restriction.</p>
<p>my arrangement currently gets all the fluid from the bottle. </p>
<p>wow! I can't wait to go to Home Depot and get one This is one less annoyance to deal with </p>
Oh yeah.
<p>I could use this at times in my daily work ,where would one get a check valve ,if they didn't have an aquarium that had a spare </p>
<p>petsmart or petco have them.</p>
<p>Ace Hardware / Home depot</p>
Neat trick!
<p>Great idea!</p>
<p>Fantastic! Thanks for sharing!</p>
<p>that's cool I hate pumping the spray bottle to get it primed or three pumps to get one squirt.wow that's like a no brainer after seeing it</p>
