Thank you for the video I have a fog machine with a timer when it’s running everything is ok but when the machine stops some nozzle continue to leak some water 💧 💦 any advice ? Thanks 🙏
For most misting or fogging nozzles there are 2 reasons why they might leak or drip following a mist. The first reason is residual pressure in the lines. If the machine stops abruptly and the equipment has a check valve there is some amount of pressurized fluid still remaining in the tubing. Until enough of the fluid leaks out of the nozzles for the check valve inside the nozzles to seal the nozzles will commonly drip. All of MistAway's systems are designed to relieve this pressure at the end of a mist to address this issue. The second reason may be worn out valves within the nozzles. Most misting nozzles are designed with an integral check valve. This can be as simple as a small spring with a rubber ball on the end. Over time these springs do weaken and naturally let fluid pass by at lower or even no pressure. Depending upon the nozzle used the spring and ball can be replaced to stop the leak. Please note that we are most qualified to provide assistance on our systems and products. If you would like to learn more please visit www.mistaway.com for more info.
Great video. I have a misting irrigation system for my vegetable garden bed consisting of 30 misting heads. This misting system is only 2 weeks old and the misters already started dripping instead of misting. I trouble shot EVERYTHING. sediment build up which there was none, water supply.. you name it. When I removed the black ball (viton plunger) attached to the spring, every single mister started working perfectly. I'm curious if these misters are poor build if that was the solution, and what possible side affects will be over time without the plungers.
We are not the authority on systems or nozzles sold by other manufacturers. However, our experience is that nozzle using a similar ball and spring design drip for one of a few reasons: 1. There is sediment passing through the nozzle creating an inconsistent seal in the ball and spring check valve. 2. The solution being misted is adversely affecting the ball of the check valve. Even viton can swell or deform when it is exposed to certain products. 3. The spring itself can wear out over time, not producing enough force to successfully seal the valve. 4. If the system has a check valve between the pump and the nozzles it can trap pressure in the lines after a mist event that will cause some amount of leaking. Our systems are designed to prevent this scenario.
It certainly can be the springs themselves as they are made of very small diameter wire. The action of opening and closing repeatedly will eventually weaken the spring itself. We sell replacement balls and springs for rebuilding our nozzles.
Do you have nozzles that produce 15 micron droplets and if so, how does pressure effect droplet size and distribution? I am interested in using a surfactant-water mixture to produce long lasting microbubbles for flow diagnostics.
So your only droplet size distribution is 40 micrometers plus or minus some standard deviation? If the standard deviation isn't too large (let's say +/- 15 microns), I may be able to work with that too and add some of your products into my feasibility study.
We do not have an recently measured standard deviation of droplet size as the last study we conducted was a number of years ago. The desired mist characteristics for our application have remained largely unchanged for the last decade. Our recommendation would be to research available nozzles in the market for a specific pressure. Nozzle manufacturers will be more likely to have the information you are seeking and possible solutions for your need.

This is exactly why Im here. I have cleaned all of my heads and still get drips from some. Im thinking its the springs

@@mistawaysystemshtx all great answers. thanks!

We do not have any nozzles that produce an average droplet size of 15 micron.
So your only droplet size distribution is 40 micrometers plus or minus some standard deviation? If the standard deviation isn't too large (let's say +/- 15 microns), I may be able to work with that too and add some of your products into my feasibility study.
By any chance, do you know the standard deviation of the droplet size? If necessary, we can proceed via email.

@@mistawaysystemshtx Okay, thanks.
