I thought about something similar. Why push/backpack water around when a hose will do? The flows are super low so a small id should work. I would think that adding a CF valve at the wand could compensate for any extra tank pressure needed.

 

This is definitely an interesting concept.

 

Yes, I'll be making a 3 nozzle boom sprayer with a feed hose. Going to use a old push spreader for the base.

Gotta move in 40 days, might make it before if I can clean my shed out in time.

I was going to use a snowblower contraption but figured it would be too heavy if it was bare ground.

Here's a picture I found of inspiration.

 

A stationary spray rig with a working hose was not uncommon in another time. Sure it had wheels, but the idea was for the hose to be uncoiled to work on an area. They were known as estate sprayers. A concept that I do not consider obsolete. In another thread we are discussing liquid fertilization. That is something best done through an estate sprayer due to the increased volume required for safety to the grass. How big a lawn are you working on? I normally want 1 gallon per 1000 sq ft or else 1 gallon applied in 2 different directions if more volume is needed.

Compressed air and vessels under pressure are something I respect. Unless the container is pressure rated to begin with like a stainless steel soda fountain keg, I would not put something under pressure. I think it is safer to withdraw liquid from a tank and use a pump to get it through hose. 1/4 hose can be used, however, there will be pressure loss that increases the more volume you want to discharge at. I use 300 ft of 3/8" hose on a commerical spray rig and use a regulator at the hand piece to reduce 400 PSI down to 40 PSI for the Teejet nozzle and spray gun.

 

I only have 6k. I will will move the tank front to back, so 4 gallons tank will work. A small wall electric pump should work, to avoid a battery. All I'm after is PGR.

 

Here's what I was referring to earlier. Found the picture on lawnsite.

 

So I got started on this project this weekend. Using 1/4" ID hose and the red tip that came with my sprayer, I was able to pump .5 gal/min. How would 3/8 hose change the outcome of that test? thanks

 

I thought about getting a skid sprayer like you would put in the back of a truck and putting it in a shed or something. That would be an all in one solution ready to go.

 

I loving all these ideas keep them coming. I will need to build something this year to spray my yard because I'm getting tired of walking with something on my back.

 

@M311att it all depends on the pump and length of hose. A larger id should help since you are loosing less energy due to friction.

 

Put on the 3/8 hose today and it pumped 5 gal in 8:30 vs 10:00 with the 1/4 hose. 100 ft of hose will nearly reach everywhere I need it to.
