12V Hand Held Sprayer

Mine is 12 volt and I used a broken drill, gutted to hold the battery. I have sealed driveways with one battery and still had juice afterwards. Works good.

There are a lot of people commenting on that sprayer on facebook, I would suggest reading about it.

Wondering what makes that sprayer better than the one I made? I'm not trying to sell or anything,..but just wondering what makes these better than mine. I see nothing myself, Ha,Ha,..

Nothing. I still use mine all the time. It is falling apart at the seams though. Being held together with duct tape. The barb broke first, then the handle cracked, then the wand is loose and flopping all over the place, then the internal hose in the handle disconnected and wouldn't draw. fixed it and it sprays good, just isn't going to last very much longer. $200 eh. I would have went through almost that much in pump ups in 7 months so I can't complain, and it reaches two stories.

Hey Jeff, those seaflo pumps you are using obviously must have viton seals or something right? I'd like to make something like that instead of spending $200 on plastic crap.
 
Actually Ralph,..the Seafllos are EPDM and Santoprene,.. They hold up well. I am only on my second one of the season. I rinse really well. They spray good and the pressure switch works well. The issue with the pump I replaced was the prime,..but once primed it sprayed fine. They are $40.00 or less each,..1.1 GPM and 70 PSI. Others available also. I started with 35 PSI,..but switched to the 70.

And honestly,..these things are abused,..it usually has a jug of 12.5% for bees nests and other tough spots,..and sits that way till I'm done with the job ,.and is then rinsed.

Ralph,..the wooden one was cheap to make,..it was made from scrap pieces I had laying around. I actually have the wooden one on board as well,..it works just as good as the aluminum one,..but is only used sparingly. But these things are awesome, and so much better than any pump sprayer will ever be.

$10.00 worth of wood,.(If you'd have to buy)
$40.00 Pump
$15.00 Battery
And another $10.00 in a switch, connectors, wiring and hose and you have a very capable spot sprayer for less than $80.00

The hose I use is the 5/16" clear vinyl stuff from Ace hardware,.and haven't had any issue with it at all.

The one thing that will not hold up to the cleaners I run through these is the triggers,..and I've tried a couple different ones,.after going through about one about every (2) weeks I've determined they are just to spendy to keep buying,..they just won't hold up to 12.5% sitting in them,..so I went back to 1/2" ball valve,.. I put a 3" piece of PVC pipe on the inlet side of the ball valve,..this gives my hand a little leverage and allows me to open and close the valve easily with one hand. And the nice thing is,..a 1/2" ball valve doesn't need to be opened all the way to have full flow,..just simply cracking it open about a 1/4 turn at most,.. and that's it,..very easy to do with one hand.

*Maybe later I will take one apart and show how it's put together on the inside.

That would awesome Jeff. I decided I am not buying another one of the plastic sprayers again. The guy who makes and sells them is a french guy who pretty much blames the operator for all the problems. His solution is to send it back to the vendor and have them replace stuff. I am sure the vendors like that! Don't really like the idea of having a piece of junk sitting there waiting for replacement parts 90% of the time.
 
Here is a picture of the inside and also the switch and charging plug to the battery,..,..fairly straight forward. The wooden one is the same inside. And everything is soldered and dielectric greased.

That little twist in the draw hose isn't as bad as it looks,..Ha,Ha,...I really didn't even notice it as much when I had it apart. Doesn't seem to affect it's spraying,.so I will just let it alone.

The cap on the draw hose on the outside of the box is always there,..when I put a jug in it simply screws onto the jug and keeps it from spilling out when moving around. The little zip tie keeps the cap from sliding down the hose and falling off.

I just looked over on facebook and cannot find the thread about that little sprayer, maybe someone deleted it?
 
The thread was started by Jeremy Dent on August 4th. No title but just search on Pressure Washing Friends and you will see it.
 
Hi Dave,..I don't think the PWS sold a hand held unit? They have a unit similar,..but it isn't a self contained unit where it all "fits" and can be carried around. If they did I never seen it. But yes,.a motorcycle battery may work,.but they are not intended for draining and charging cycles like a deep cycle. The battery I use is only about 3 lbs. Not much difference and a whole lot cheaper than a motorcycle battery.

As far as weight,..the one I have is around 20 pounds with a full jug,..but it is a spot sprayer,.not a large area sprayer,..It's meant to be used sparingly on a job.

Jeff
 
That's the one I figured you meant,.mine is really nothing like that. If you look at the first pictures in this thread you'll see that the one I made is a truly hand held unit that carries a (1) gallon jug along with the unit. A true spot sprayer,..for hitting small rust areas or using it too zap a bees nest with 12.5% . Maybe too heavy for some,..but I made it as a spot sprayer and it doesn't bother me to use it where I previously used a pump sprayer. Handling it for about 2-10 minutes per job.

The one from PWS looks as more like it is made to be set down beside a jug or bucket and then use the extended hose to do your application. Is why it comes with 25' of hose. I have one on a cart I use for that type of applicator. Mine is made to carry the who unit in one hand and run the trigger with the other with only about 18 inches of hose,... opposed to 25 feet.

I agree,.I wouldn't want to carry that thing around neither with the battery people use in them. My design will do everything that one will do,..and more. Not to mention the components in mine are totally protected,..no overspray of cleaners or water will ever affect it.

Jeff
 
I really like the idea of the 1 gallon jug on the sprayer, small and efficient.

I was thinking that maybe mound the pump to a board and let the board slide down into a slot with a cover over it and if the pump needs to be replaced, just disconnect the hoses,open the top, disconnect the wires and slide the board out to replace the pump.

I don't think any vendor has made one where it holds a gallon jug so the sprayer and chemical can be held in one hand and the gun in the other hand.

I think I might try to build one.

Do you have the measurements of the wood sprayer Jeff?
 
Hey Christopher,..no I don't have the measurements on hand,...I will try in the next few days to break the wooden one down and post the measurements. It's actually a very simple build. It is just squares and rectangles,..Ha,Ha,..

Jeff
 
That is ok, I was thinking of building something similar to try out, out of wood to see how I like it. I think I can figure out the measurements more or less based on the size of a gallon jug. Thanks.
 
Hey Christopher,..I changed the routing of the hoses in both sprayers shortly after the pictures were taken,..they now both come out the front,.. above the jug. Much better than out the side like the pictures show. I also use lightweight,..cheap clear vinyl hose from Ace Hardware and it has been just fine. No issues with it at all,..with anything I've run through it. But there isn't a trigger I've found that will hold up,..so I now use 1/2" ball valve setup,..easy to turn with one hand and only needs to be cracked open to have full flow,...no need to open it all the way.

The inside is the same as the aluminum sprayer,..but I used drywall screws to hold the pump and battery retainer in place. Also added a better handle shortly after the first photos.
One thing about this wooden one is,..it's quieter than the aluminum,..the wood dampens the vibration of the pump better. And,. they are about the same weight.

Both were made with holes in the bottom,..in case of a bad leak,..and also to access the pressure switch.

Here's how it looks today.
