Mist system

**Chris** · 02-10-2010, 08:10 PM

On the BBQ and patio I am building I would like to install a mist system. Is there any kits or place I can get the parts to put it together? I get's above 100 most of the summer and it would be nice to cool it down a few degrees.

Make your own system. This way it will look custom and look cleaner than the store bought mist systems. I installed a custom system at my Havasu house that wraps around 70' of patio. I used 1/2" PVC and placed the nozzles about 7' apart from each other. You can use plastic electrical conduit clamps to install it to your edging.

Make sure your actual nozzles are brass and clean them often. One important element is to install a good pre-filter and change it every season, or you might have everything coated in white after a few months from the calcium. I also installed a ball valve at the end of the line, which allows the pipe to be emptied quickly so as to avoid water dripping for hours after the system is shut down.

As far as the brass nozzles, you can purchase them at most big box hardware stores, and are screwed into 1/2" PVC slip/slip fittings.

I own a company that caters to these products but I recommend Aero-Mist.

Ask for Niko. I plan on buying from this company for my upcoming summer.

I don't want to come across as the voice of doom, but I bought a cheap system, installed it (the nozzles were brass though) and in a few days all but one of the nozzles were plugged up with hard water. I have about 15 grains of hardness and very low iron content. I guess if your have soft water to hook one to, it would last a little longer. I also bought the inline filter they suggested and that didn't help a bit. (I never liked those things anyway) I also bought a little bottle of the liquid they sold to clean the nozzles. Don't waste your money.

In my limited opinion, this is a great idea if you don't mind doing the maintenance. They do drop the temp about 10° but you will get wet before long.

Thanks I may end up doing the same. Where did you get your nozzles? I already have pipe and ball valves. I do waterworks for a living (Like a plumber but with the big stuff)

I have heard this alot but I am still willing to take a chance, What do you think about taking the nozzles off and soaking them in something like CLR every now and then? Do you think that would work? Also maybe what Havasu says about draining the line when you are not using it will help with the build up.

Draining the pipe will keep it from dripping after being shut off. I know mine did the same thing. Seems like it would never quit dripping.

I have never had any luck with CLR. I have had people tell me how great it is, but it just doesn't work for me. Maybe Vinegar for the calcium/magnesium, Muriatic for sulphur, Iron out for iron etc.

All I know for sure is that it didn't take me long to tear the whole mess down out of frustration and throw it into the garbage.

In my limited opinion, this is a great idea if you don't mind doing the maintenance. They do drop the temp about 10° but you will get wet before long.

They drop the temperature anywhere from 10-30 degrees, all dictated by humidity, sunlight, ambient temperature, wind speed. The best application is against buildings where the sunlight is beating off the brick or concrete, or large paved areas where the sun is reflecting, including roofs.

The "quality" of these systems are all dictated on the cost of product and pressures involved. If you spent less than $100 on mist line then you'll get slightly above a wet mist.

The systems I operate are high pressure with 3 different filtrations before it leads to the nozzle itself.

I run ceramic/stainless steel nozzles as they above the line in quality, longer lasting.

A true misting system will run into the hundreds which most are reluctant to spend. http://www.aeromist.com/

Anything that operates off of the water pressure of a home only will be a wet mist all the way.

High pressure misting involves micro-misting and in relation to the sun, flash evaporation is created.

In this video,

Example of Misting

the girl and the dog I'm speaking to is not getting wet, and she's less than 6 feet from the misting fan.

That pump is running at 750psi through 6 nozzles in combination with a 7800 cfm fan.

If you look at the top of the screen you see at the front opening of the tent a mist line dropping mist to the entrance. People absolutely loved the comfort it created.

Here's a $19.99 answer

The quality systems incorporate no-drip nozzles which are spring loaded and instantly seal off when the required pressure stops.

Brass nozzles are fine, but not for long term uses. I however had brass nozzles last 10 years under a deck, used it year to year and just replaced nozzles when they stopped flowing. Cheap like $3.40 a nozzle.

The filters I use on my systems are more dense than a cigarrette filter, has to be to protect the pump system and all the components.

Before installing the ball valve drain, my lines would constantly drip and become clogged with calcium. After installation of the drain valve, I only have to clean the brass maybe once a season.

I've also used their recommended expensive bottle of mist nozzle cleaner, which I found was junk. I remove the screw in nozzles, place them in a small coffee cup, and use white vinegar to soak them for a few hours. That seems to work pretty well.

Another plus of the ball valve is when I turn on the system, I allow the line to flush for a minute, which allows the dried calcium to purge out of the line before closing it. This allows a longer usage between cleanings.

Also, as stated before, the brass nozzles can be purchased at most bog box hardware stores.

Keep in mind that mist systems work best with very low humidity situations. In high humidity, you will see that your patio furniture will become wet and just as uncomfortable as with not using the misters.

It would seem to me that it would be rather expensive running ice water through these nozzles.

If I am going to spend that kind of money on one of these systems, I'll just go inside to the AC.

The same mentality when people extensively spend on private water systems,

eventually switch to city water and it ends that costly misery of constant spending through bladder tanks, pumps, well issues.

Stainless steel denotes a one time purchase in that product choice, unlike many components found in water distribution systems as I well know both sides of that equation.
