“Don’t Get Left Out In The Cold This Year!”
What do water well and water softener systems have in common?
Unprotected, they can and do freeze. Both systems can cost thousands of dollars to repair. Bee Cave Drilling is now offering Freeze Miser, the outdoor faucet freeze protector! The new method of freeze protection senses the internal water temperature. It’s activation temperature is 37 °F. Until the activation temperature is attained, no water will be allowed to drip. The Freeze Miser™ will release a minimum amount of water until the internal water temperature is again above 37 °F and then stop the water release. Give us a call today and ask about the Freeze Miser, you can pick one up at our location or from any one of our trucks around the Austin and surrounding areas. If you would prefer to have one of our technicians install it for you just give us a call (labor and trip charges will apply). Don’t let Mr. Freeze Miser get you this year!
The Freeze Miser senses the internal water temperature. Its activation temperature is 37 °F. Until the activation temperature is attained, no water will be allowed to drip. After the water temperature has dropped to 37 °F or slightly below, the Freeze Miser will release a minimum amount of water until the internal water temperature is again above 37 °F and then stop the water release. Water utilities, water wells etc. almost always supply water to the end user that is well above 37 °F.
Freeze Purge Valve
The Freeze Purge Valve™ is the most sophisticated and fastest temperature controlled freeze protection valve available. Installed as suggested, it will provide many years of freeze protection.
Have you ever had your water well freeze up? No water in the house. Worried that pipes would freeze and rupture. Have you ever had the lights on in the well house but the lights burned out, no heat, or maybe the cold wind blew the door open that was not securely closed to begin with? You spent two hours insulating the pipes at the well and that worked ok, but the pressure switch diaphragm froze so that the well pump never stated pumping again after the pressure tank ran out of water. It was extremely cold and the insulation kept the pipes from freezing for a while, but eventually the cold soaked through and they still froze. This took away the ability to drip faucets in and around the house which increased the problem!
Congratulations! You obviously have seen the effects of that scenario and would like to find a solution. We offer this technology at Bee Cave Drilling! All the insulation you wrapped, the building you placed around the well, the lights you burn for heat are still there, but you want a solution that works through the “I never would have believed it would freeze that way scenario”.
We call it the Freeze Purge Valve™. Its patent pending technology means it’s one of a kind and designed for the water well owner to install and rest easy on the coldest of nights, knowing that the water well unit will not be frozen and out of service because of it.
How It Installs
The Freeze Purge Valve™ is a precision made, temperature actuated valve using materials of the highest quality for a long working life. It also meets the NSF-61 and NSF-372 standards, which means it has been tested for performance and code against stringent criteria.
In a water well, freeze protection format, the Freeze Purge Valve™ is placed as close to the bottom of the existing pressure switch as possible. A “tee” is furnished with the well application version. One end should be threaded into the check valve and the opposite end into the pressure switch. Install the Freeze Purge Valve™ into the female port of the “tee”. Do not over tighten. The valve has a barbed hose fitting with enough hose to go from the valve to the vent hole in the well casing cover. Most well casing covers will have a vent hole that can be used. They are typically 1/4″ or1/2″ threaded. If it is 1/2″, install the 1/2″ x 1/4″ included bushing to reduce the opening to 1/4″. The tubing should project 2-3 feet inside the well casing.
How it Works
The Freeze Purge Valve™ works by purging water from the system that has reached a temperature close to freezing. Its temperature activated mechanism adjusts to automatically discharge “ONLY” water that is below its actuation pre-set temperature of approximately 37° F (3° C) so that the water discharged is replaced by warmer water as the well pump eventually cycles on.
In a water well system, the pressure switch is typically the “Achilles Heel” of the system. If the pressure switch freezes, then the pump never turns on and when the pressure tank runs out of water, the pipes start freezing and rupturing as a result. The pressure switch, typically, has a diaphragm on the bottom of the device that holds a very small amount of pressurized water. It is a dead end, which means that water does not flow through it, but stops there. This tiny volume of water will probably be the first thing that freezes in a water well unit. If it freezes, the well pump never gets a signal to turn on because the pressure switch is incapacitated until it thaws out.
The Freeze Purge Valve™ monitors the water temperature close to the pressure switch. The valve has an extremely fast response, discharging just enough water to keep the pressure switch from freezing. This water is not wasted and does not create a mess as it is directed back down the well casing via the included tubing. CAUTION: Never wrap, apply heat tape or tamper with the Freeze Purge Valve™. It arrives ready to work. Anything added to it will affect its ability to sense the true temperature.
The job of a well pump is to supply water to the pressure tank and when the tank is full and the pressure within is consistent with the pressure setting, the pressure switch turns the pump off. The pressure tank then provides water to any valves that are opened until the pressure drops to the low pressure setting. At this point, the pressure switch closes, turning on the well pump to compete the cycle.
As a result, the water being purged from the system by the Freeze Purge Valve™ is that water from the pressure tank. This is very advantageous. The pressure tank, typically with 20-50 gallons of working capacity, is also subject to freezing and causing problems.
As the Freeze Purge Valve™ prevents the pressure switch from freezing by purging cold water away from it, it is using the water from the pressure tank. As the water in the pressure tank becomes colder, the flow of water discharged by the Freeze Purge Valve™ will increase from a drip to a brief stream and increase further as the temperature of the pressure tank drops. This will prevent the tank and associated piping and valves from freezing.
As the pressure decreases, the pressure switch (because it’s safe from freezing also) activates the well pump and the whole of the water well assembly is filled with warmer water from deep in the ground that typically will dance around 50-60° F. The cycle then starts over.
A unique feature of the Freeze Purge Valve™ is that the valve senses both air and water temperature. Sensing air temperature alone will not totally make it function, but it primes the system to be extremely sensitive to the water temperature and react quickly. This double temperature sensing sets it apart from other temperature actuated valves. It means a super-fast response time. This is essential for effectively protecting the pressure switch.
The short piece of pipe that is typically between the check valve and the well seal should be insulated. The water within it is not directly protected by the Freeze Purge Valve™, but it receives a delayed freeze protection benefit every time the pressure switch turns the pump on and flushes it with warmer water.
