Most expansion tanks have a one- to five-year warranty, so expect to replace yours every two to six years, and whenever you need to replace your hot water heater.

Keeping your water heater system healthy often requires an expansion tank. As we’ve mentioned, a plumbing system is either open or closed. With an open water heater system, any water that has increased in volume and pressure due to heating is freely passed from the storage tank into the cold water supply line, eventually passing in through the municipal water system if the pressure is high enough.

The water purification process occurs as the water goes through the reverse osmosis membrane. Both water filtration systems aid in reducing the hardness level and TDS level (total dissolved solid). A reverse osmosis water purification system is perfect in areas like Southern California, where there are hard water problems and the tap water/drinking water can have a chlorine taste depending on what region you’re in because it is extremely concentrated with other unwanted minerals and contaminants. Many of our customers immediately notice the difference of using treated water from our RO systems.

There are different types of home water filtration systems available in today’s market, but one of the emerging popular options is a reverse osmosis system. However, many people are unsure of what a Reverse Osmosis water filter is and the benefits of using this type of water treatment system. Simply put, unfiltered water is pushed through a reverse osmosis membrane (semi permeable membrane) that removes impurities, contaminants and unwanted dissolved solids.

Many water companies will claim that water softeners or a reverse osmosis water filter system will deliver 100% pure water, this is simply not a fact. From a technical perspective, water softeners and RO systems help reduce the hardness of water significantly and greatly improve the quality; however no company can claim to provide 100% pure water. While many people debate whether to get an RO water system, water filter, or water softener, we feel using a combination of these for your household is the best overall water treatment system solution. Experience the difference of filtered water in your home or utilize our commercial RO system for your business! Please note, replacement filters are needed roughly every 18 – 24 months for reverse osmosis water filters as part of routine maintenance. Contact us today and let us help you select the right RO unit for you!

An expansion tank is installed on the water supply pipe of the water heater and is designed to handle the thermal expansion of the water that occurs when the water heats up. The expansion tank prevents the water pressure from getting too high, thereby protecting your water system from being too hot, damage, or even an explosion.

In open water systems, there is nothing to prevent the water pressure from rising, so the pressure in the open system is equal to the supply pressure.

Expansion tanks are a component of a hot water heater. Residential expansion tanks look a lot like small propane tanks with an air valve on the top and a threaded pipe connection on the bottom. They are typically around the size of a basketball, though can be much bigger for larger water heaters.

You may be asking yourself, “If water purification products all do the same thing, why are there so many options?”. Clean water is clean water right? Well not exactly, the key difference between water softeners and reverse osmosis filtration is that an RO membrane (semi permeable membrane) completely filters out water contaminants (total dissolved solids, minerals and heavy metals like lead, arsenic, fluoride, iron, mercury, sodium and many more) from the feed water while a softener removes and addresses issues caused by hard water, via ionization. Water treatment systems come in all shapes and sizes including ones with carbon filtration, reverse osmosis, and more. However, in our opinion, a whole house water filtration solution that incorporates both an RO filter and a water softener is ideal for the best quality water.

As a water filtration system, along with producing the treated water, an RO system can filter out harmful contaminants like:

So what is the purpose of an expansion tank on a water heater? In a closed water system, the hot water expansion tank houses the increased pressure and expanded water.

You may be wondering how to install a water heater expansion tank, but you can’t do that without knowing what size you need. The size of the expansion tank required depends on the size of your water heater. The larger the water heater, the larger your expansion tank needs to be. There is no “one size fits all” option.

After the dissolved contaminants are filtered and removed, the freshly filtered water, or permeate, flows to the storage tank, where it is held until needed. RO water has an amazingly clean taste that you’ll notice right away. No more chlorine taste from treated tap water. If you live in an area with poor water quality, it is highly recommended to switch to RO water filtration. Upgrade to a RO unit system and remove those impurities from your water supply.

The Rayne Clear 3 Stage Reverse Osmosis purified water system effectively reduces 95-97% of Total Dissolved Solids, dissolved salts, dissolved minerals, and other harmful contaminants within your water supply. The basic reverse osmosis water system could be the purification tool that solves your water problems.

Without a hot water tank expansion tank on a closed plumbing system, the water pressure could build and build, getting high enough to damage valves, plumbing fixtures, supply pipes, and even the water heater itself, causing water heater leakage and other serious harm. A properly installed expansion tank absorbs excess pressure and prevents issues like these.

The Rayne Pure Plus 4 Stage Residential Reverse Osmosis water filter system, with a post-carbon filter for a great fresh taste, effectively reduces 95-97% of Total Dissolved Solids and other harmful contaminants. This could be the right water filtration system for your home.

The two factors you need to consider is your water heater capacity (which can typically be found on your water heater’s factory label) and the household water pressure (which is measured in pounds per square inch and can usually be found by your home’s water pressure gauge).

Always get your expansion tank installed by a skilled professional and consider replacing them no more than a year after the expansion tank warranty has expired. Otherwise, you may end up with a lot of water damage and no warranty to help you out.

Whether or not your water heater requires a hot water tank expansion tank to operate depends on what type of plumbing system you have. Homes either have an open or a closed water heater plumbing system and if yours is the latter, then you’ll need an expansion tank to allow your water heater to operate.

With a closed water heater system, however, water cannot expand beyond what the valves in the system allow. These values usually include a check value, pressure reduction valve, backflow prevention, mixing valve, and sometimes others. A closed plumbing system prevents water from flowing in the reverse, meaning it won’t go back into the city lines once entering your home’s piping.

Once you’ve determined your water heater’s capacity and the household water pressure, you can find an expansion tank to suit it by using sizing graphs or by consulting a licensed plumber. Typically a 2-gallon expansion tank works with a water heater with a 40 to 60-gallon capacity and a psi of 40 to 50. A 4.5-gallon expansion tank is needed for larger water heaters, such as ones that hold 80 gallons with 80 psi.

There are many variables that make predicting the life expectancy of an expansion tank difficult to impossible. The quality of the tank, the skill of the installation technician, water quality, and proper inflation all have an effect on how long your expansion tank will last. Some tanks last as little as two years while others last as many as eight.

Most newer homes are built with a closed plumbing system rather than an open one, so it is very possible that your water heater needs an expansion tank. We’ll answer more questions below, such as what is an expansion tank, the role it plays, and more.
