Time to Winterize: Waterville Irrigationinc

If you live in Ohio, then you know and understand how hard the winter months can be on your lawn, landscaping, and property in general. When it comes to Sprinkler Companies Perrysburg and Irrigation Services Perrysburg, the professionals at Waterville Irrigation have the skills and equipment to winterize your entire system. If you do not already have an irrigation system in place, Waterville Irrigation also offers an array of other services, including Irrigation System Installation Perrysburg.

Winterizing Your System

When it comes to winterizing your irrigation sprinkler system, the professionals at Waterville irrigation will shut off the water supply to your system. The main shutoff valve for your irrigation system must be protected throughout the entire winter so that no freezing occurs. This can rupture and damage the pipes and other equipment associated with your irrigation and sprinkler system. They will ensure that your system is wrapped properly in a foam type of insulation by using a plastic bag and foam insulation tape along with it to ensure that your system is kept warm and toasty throughout the chilly Ohio winter months. If your system does not have a main shutoff valve, the technicians from Waterville irrigation can install one for you.

It is imperative that you stay in control of your system throughout the winter months. This means if you have an automated system, you will need to have the controller or timer of your system shut down for the winter months. Most controllers also have a rain mode which will shut off the signals to the valves, so they stop working when they need to. The controller continues to keep time, yet the programming information is still present, and this clock continues to operate throughout the winter. The change that the technicians from Waterville Irrigation will make is to change it up so that the valves will not activate during the winter and cause a very frozen and dangerous situation for your system. This will help prevent the possibility of the pump to your system being turned on accidentally, which can then cause damage from overheating. There is an alternative to using the rain mode since you can simply shut off the power to the controller. If you take that route, you just need to remember that it will need to be reprogrammed for the correct time and other settings as well when springtime rolls around. The professionals at Waterville Irrigation can assist with that also.

Contact Us

Our irrigation and sprinkler specialists at Waterville Irrigation are prepared to drain the pipes of your system and ensure that the valves and backflow preventors are in place to protect your system throughout the winter. Waterville Irrigation is locally owned and operated so you will be provided with the personalized service that Waterville Irrigation is known for. Call today for an appointment to have an irrigation system installed or to have your current system winterized properly so you can have the peace of mind you need and deserve over the winter months.

Small drip?

Hi all - apologies for another post, but after having some work done on our boiler and piping yesterday we've discovered a drip every 30 seconds or so.

It's not dripping on anything and I don't think they even touched the backflow preventor or fill valve, but the drip is definitely new.

They did have to flush and refill the system to do the work, so perhaps they did tinker with this after all? Apologies, I know enough to ID the components, but not enough to really grasp what's going on.

Is this:

not something I should worry about, no mold issue

something I should bring the HVAC folks back to resolve

a "just spray it with flex seal" scenario

How Plumbing Works

supply and wastewater never meet so we've gone through all kinds of plumbing acrobatics over the decades to make sure that the wastewater from your building doesn't contaminate the water supply that we all share one of the ways we do it is really quite simple it's an air gap between the the faucet and any kind of basin so that air gap makes sure that if the basin backs up the faucet isn't buried in the water and therefore won't be a opportunity to siphon dirty water back into our municipal supply we've come a long way and cholera is something that we just don't really see anymore and that's pretty remarkable I mean the thing about plumbing is the more I study it the less interesting it is but the more fascinating it is to me that we actually pulled this off because it's an amazing feat and when you see that you know at the end of the last century at the end of the 2000s I saw the end of the you know end of the 19th 1999 at the New York New Year's I saw all kinds of greatest accomplishments of the 20th century and greatest engineering achievements and so forth and plumbing was always really high up usually like second or third I mean it was often above computing and above aircraft and above automobiles telephones all kinds of things that we think of as being frankly a little bit more technologically important but just providing clean drinking water to our buildings and then being able to get waste water away from our buildings in a sanitary way that's a really big deal the second way we do that is with what's called a backflow preventor there's several different flavors of backflow preventor but one of them is called a vacuum breaker and that's what you see here in the middle image it's in this case it's a toilet so what happens is and I'll show you an example in a little bit the way a backflow preventer works is the water moves one way the way it's supposed to run and everything works fine should water back up should there be a siphon that may take unsanitary back to our supply system then instead of pulling from the water a little a little kind of mechanism makes it so that air fills the pipe so water moves one way but if it backs up the water isn't allowed to move in air enters the system and and allows the siphon to draw air instead of water where this might be a problem is well say there's you know the fire department might often usually almost always uses the same supply system that buildings use so if there's let's say a fire in the neighborhood you wouldn't want to condition where the fire department is using the hoses and it's creating a negative pressure and everything and it's actually trying to suck back we don't want that we don't want a situation where for instance a hose is been used to fill a baby pool the baby pool has been sitting there for three weeks because you went on vacation forgetting about it and now the holes in the algae filled baby pool water if there's a fire in the neighborhood we don't want a negative pressure on the supply line that would actually suck the algae filled water back through the supply system we'd rather not have that so that's what we use something like a vacuum breaker this is a good time to introduce types of valves we have a gate valve we have a globe valve and we have a check valve each serves a specific purpose and frankly these are kind of old-fashioned names for them they've since been superseded the gate valve looks like a gate I'm going to screws down into the shut-off position it pretty much sets everything else and when it opens up it you see kind of stays out of the way and doesn't add a lot of friction to the system we use gate valves we engage gate valves if we want to do maintenance on the system so there may be one for the whole building and there's probably also one for each of the appliances inside the building we can shut off the gate valve to say our dishwasher and then we can do maintenance to our dishwasher or we can shut off the gate valve to say our entire building and then we could do maintenance to the entire building now the globe valve is kind of the opposite the gate valve is not made to be used all the time it's not made to be a particularly comfortable mode of turning on and off the water and you have to turn and turn and turn is this gate screws in and to engage and screws out to retract the globe valve is a bit different the globe valve is what we might use for sail faucet in the case of the globe valve if you look at it you can see as water moves through it there's quite a lot of friction but it's made for repeated use so it's made to be comfortable it's made so you don't have to unscrew it too many times to open it up and we're not too worried about the extra friction because it's like a faucet where it's only really at the end of the line for one particular fixture a gate valve may be in line for the entire building so we wouldn't want it to create a lot of friction downstream the third type of valve is called a check valve and check valve is a backflow preventer much like the vacuum breaker and you could see the waters allowed to move one direction but not the other and often what happens is right when the water moves into the building there's a check valve and that check valve is required by code because it wants to make sure that if for some reason there was a siphon it's one more way to make sure that we're not contaminating from our building the water supply for the other the other people in the municipality let's go ahead and do number 36 number 36 reads a water tank is 75 feet above a fixture what will the pressure be at the fixture you may ignore losses from friction for this exercise and we're given a formula that pressure is equal to zero point four three three times height go ahead and hit pause all right let's go over number 36 and the municipality here's how it generally works we have a reservoir we have a water tower we have a pump that takes water up to the water tower and it holds it in the water tower and the water tower is often on top of the hill then somewhere else lower than the water tower we have our building and we have a fixture in this case the fixture is 75 feet below the top of the water and water seeks its own level the amount of pressure in the fixture is a function of the height of the water above the texture the higher the water the more the pressure

What is a Special Hazard System? A special hazard fire suppression system is typically used in areas where the facilities or assets need to be preserved or water damage would be costly. Special hazard environments demand only the most advanced, reliable fire suppression systems Special hazard systems are designed to detect and extinguish dangerous situations in locations where standard fire suppression systems are not sufficient.

A&D technicians have the experience and expertise to service, inspect and maintain your specific suppression system.  Our objective is to provide top- quality fire protection systems that meet all your fire protection needs and requirements.  Fire Protection prevents extensive property damage, business interruptions, and most important, save lives.

How do I maintain my Special Hazard System?

At a minimum, all systems shall be thoroughly inspected, tested and documented for proper operation on an annual basis.  This maintenance should be completed by trained and qualified personnel.  Our team of fire protection specialists have years of experience maintaining, servicing and installing special hazard systems.

https://adfiresprinklers.com/service-and-inspection/

Benefits of Special Hazard Systems

Designed to limit the loss of assets, information and high-value irreplaceable assets.

Designed to quickly detect a fire or high heat condition.

Designed to suppress fires when sprinklers are not appropriate as the first and only means of protection.

Designed to protect people and prevent business interruption.

Require specially trained and qualified personnel to design, install, service and maintain these systems.

All systems should be thoroughly inspected, tested and documented for proper operation.

Whether you are looking to protect a small IT room, a record storage facility, or even a large substation, our experienced team will design and provide the special hazard system to protect your valuable product. From FM 200, Novec 1230, High/ Low-pressure CO2, and various INERGEN systems, A&D can provide the ideal solution to your exact suppression needs.

FM 200

FM-200 is a clean, gaseous agent containing no particles or oily residues. The FM- 200 Fire Suppression System is an engineered system in a protected area, typical areas that can be protected by an FM-200 system are:

Bank Vaults

Data Centers

Electronic Data Processing

Studios Communication Centers

Control Rooms

Test Laboratories

Flammable Liquid Storage

80% of FM-200 firefighting effectiveness is achieved through heat absorption and 20% through direct chemical means (action of the fluorine radical on the chain reaction of a flame).

Complete suppression using FM-200 has the following advantages:

The low concentration of FM-200 required means less visual obscurity and minimal risk to personnel.

The small quantity of agent discharged minimizes over pressurization of the protected area.

Novec 1230

Novec 1230 extinguishes the fire in seconds before it even starts and long before water-based systems discharge.  Novec 1230 fire protection fluid extinguishes fire primarily by removing heat from the fire. It is also electrically non-conductive.

High/Low-pressure CO2

Carbon dioxide (CO2) is a colorless, odorless, and chemically inert gas that is both readily available and electrically non-conductive. It extinguishes fire primarily by lowering the level of oxygen that supports combustion in a protected area. This mechanism of fire suppression makes CO2 suppression systems highly effective, requiring minimal clean-up, but should be used in normally unoccupied hazard locations or otherwise avoided by personnel when discharged.

INERGEN Systems-

INERGEN is a highly effective fire suppression system for extinguishing fire & preventing re-ignition with no risk to people or damage to equipment if engineered and installed by a qualified fire suppression systems installation company.
