DIY pressurized water tank update

Don't they make them pilotless now? Seems silly to have a pilot light running continuously off of a small tank supply.

 

When the unit senses any water pressure, it ignites the heater... so I guess you are right there isn't necessarily a constant pilot.

 

You can dramatically improve adhesion by giving the surface some "tooth", thoroughly roughening the surface with very coarse sandpaper then use plastic specific paint. A smooth finish isn't the goal here anyway.

 

These are posted in the groupbuy forums and a good product. I have two of them.

 

Can they ONLY be pressurized with a hose?

 

Are you asking if a pump could be used?

 

Just throwing this out here in the wind, and letting the dust settle it - another low cost air pressurized water tank option may be one of these; a food grade reverse osmosis pressure tank:

The 4-gallon one may be a good choice:

Keep in mind with these though, you need to use a water pump (like a 12v RV water pump) or house hose, not an air pump, to pressurize it. The air chamber is a balloon and expands while the water gets pushed out.

 

no you can run a pump as well. I thought about doing that as well. there's some pretty affordable pumps from web you can use as well.

 

Anyone have insight into this? Yes - it does take a lot of space but for 16 gallons it seems to be a legit option for long haul trips. Stumbled across a Jeep forum and a guy modified this to have a standard hose sprayer on it.

 

Insight into what?

 

If that would be a viable option for someone not wanting to pay 199 for a puny 3 gallon waterport

 

LMAO I am a fucking dipshit. https://www.northerntool.com/shop/t...ol.com/shop/tools/product_200578571_200578571

 

Looks like a nice rig. Keep in mind its a glorified garden sprayer but with a different nozzle 2.2 gpm seems adequate.

 

check tractor supply feed or whatever the name is they have some pretty cool "sprayers" that are rectangular in shaped ones that might fit the bed better

 

Another option would just be some sort of resevoir. And a cordless or 12volt pressure pump hooked up to the outlet and a sprayer. Could potentially make it as big or small as you want.

I made something very similar to yours, two something's to be specific, and so far after over a year using at least one of them regularly I can say they work awesome. For anyone going through the trouble of building a custom tank like these go as big as possible. Mine are 8-9 gallons each and I wish I had more.

 

It isn't metal and I don't see those exact dimensions, but this place could build something if anyone can.

Get whatever size you want!! The price on these is great. I would check to see if the tanks are food grade..

Probably ok but still good to check if you want to drink the H2O.

I got the waterport. I don't need that much capacity. Just enough to water the dog after running in the heat and the waterport sure beats hauling around jugs - just for convenience.

 

Just took a quick look at their website. I can't find the height of tank that I'm looking for, so I'd probably have to get a quote on a custom one....wonder how much that would cost to set up the tooling and build a new one. They have a form to fill out, but I might call them first to see what the ballpark price is.
