To get the proper expansion tank volume we need to add together the draw down capacity requirement and the thermal expansion requirement to get an additional 18% total volume required for the expansion tank. Most coolant systems are designed to operate with about 13 qts in the system. If we use a 13 qt system as our model. We would use the calculations below:

For a small private properties, mechanical new devices may cost around $200, and a Reduced Pressure Backflow Preventer may cost around $500.

The most reliable type of backflow prevention device for commercial and industrial activities is the RPZ valve. This device uses two check valves to prevent backflow. It is more expensive than other types of devices, but it is more reliable and requires less maintenance.

In an unwanted reverse flow situation, the water in your property's pipes will start to backflow towards the main water supply. If this happens, it is possible for dirty water and contaminated fluids to into the main water supply –  contaminating it for everyone.

If you need advice make sure to consult some backflow plumbers. A licensed plumbing contractor can also help you with the installation of your backflow prevention device.

However, if there is a drop in water pressure on the main supply side – for example, during a fire fighting operation when all the water pumps in fire hose reels are operating at the same time – the water pressure in your property's pipes may drop below that of the main water supply. This is because of the reverse flow of water.

First, let's discuss backflow for those who may not be familiar with the term. Backflow occurs when water from an upstream source flow backwards into your home or business's plumbing system. Water supply sources could be anything from a garden hose to an irrigation system.

When a new gas pipe is necessary, most homeowners refuse to tackle this project due to the dangers. And it's completely understandable considering the sensitive nature of gas lines.

Drawdown capacity is the amount of coolant that can be lost before air reaches the water pump and is introduced into the system. Air bubbles in the coolant system can cause inconsistent cooling and can also prevent the thermostat from opening if an air bubble gets trapped underneath it.

When purchasing a backflow prevention device, it is important to make sure that you get the right size for your property.

residential properties such as unit complexes and apartments, we recommend the double Check Valve. This device is more expensive than the Reduced Pressure Backflow Preventer, but it is more reliable and will require less maintenance.

If you are running a commercial or industrial activity, it is important to have a backflow prevention device installed on your property. This will help to keep your drinking water safe and prevent backflow from happening. Especially If you have machinery connected to your water supply.

Tempering valves are simply a 3-way mixing valve that combine hot and cold water to produce warm water at the outlet to a pre-determined set temperature.

A Reduced Pressure Backflow Preventer is a type of mechanical backflow prevention device. It works by using a series of check valves to keep water flowing in one direction only.

This series is suitable for water supply pressures up to 300psi (20.7 bar) and may be adjusted from 25 - 75psi (172 - 517 kPa). The standard setting is 50psi ( ...

The flow-rate effect on capacity is small up to 4 gpm per cubic foot. At higher flows, the capacity is more severely affected. Extremely low flows of less than ...

The general rule of thumb for proper capacity of expansion is 12% of total coolant volume for draw down and 6% of the total volume for thermal expansion.

Each type of device works in a slightly different way, but they all ultimately achieve the same goal – to prevent backflow from happening.

For commercial and industrial properties, where chemical injection area is present, the cost of a backflow prevention device can be $1,000 or more.

Mechanical devices use physical barriers to prevent backflow. These devices are typically less expensive than valves, but require more maintenance and are not as reliable.

In a 13 qt System a 2.34 qt expansion tank would be required. In a situation where a large enough tank isn't available a recovery tank can be used in order to take up some of the expansion volume needed. A recovery tank will collect any coolant that is expelled from the pressure relief. In a set up with a recovery tank it is important to make sure that the coolant system is still full enough to allow for drawdown.   For more info on setting up your coolant tank system, see our "Setting up Your Cooling System" blog post.

Water supply system and reservoirs such as underground rainwater tank are typically under constant pressure. This pressure keeps the water flowing through water supply pipes in one direction only – from the supply source to your property.

The main job of an expansion tank has to do with, not surprisingly, expansion.  As a basic requirement, expansion tanks should allow enough space for coolant to expand at normal operating temperature and not be pushed out of the pressure relief fitting in the neck.

The most reliable type of backflow prevention device is the dual check valve or RPZ velves. This device uses two check valves to prevent backflow. Dual check valves are more expensive than other types of devices, but they are more reliable and require less maintenance.

The device is installed inline with your property's water supply pipes. It has two ports – one for the incoming water supply, and one for the outgoing water.

This can happen for a variety of reasons but is most often caused by a change in water pressure. Backflow can introduce contaminants into your water supply, which can be dangerous to your health.

A backflow valve is installed on your property to allow backflow to happen. This is usually done to allow water to be drained from your property in the event of a power outage or other emergency.

A 4.5-gallon expansion tank is needed for larger water heaters, such as ones that hold 80 gallons with 80 psi. If you're wondering how to install a water heater ...

For laundries hospitals and factories, we also recommend the RPZ valve. This is the most reliable type of backflow prevention device, and will require less maintenance.

If you are looking for a backflow prevention device for your home, we recommend the Reduced Pressure Backflow Preventer. This device is more reliable than mechanical devices, and requires less maintenance.

Thermal expansion occurs as coolant accumulates heat from the engine.  The 6% of the expansion volume is calculated from the amount that the coolant level will rise at 212 degrees F. This takes into account the density change of the coolant itself and all the components that are in the coolant system. If the volume is calculated incorrectly and an inadequate expansion space is provided coolant will be discharged from the system at operating temperature.  To prevent the possibility of spilling coolant a catch tank or a recovery tank can be used.
