There are several types of tempering valves in use today. They are all 3-way valves, meaning that they have two inputs (hot and cold water) and one output (tempered hot water). They are named based upon the type of control used to maintain the tempered hot water temperature.

ThermostaticMixing valvefor eyewash station

A thermostatic mixing valve (TMV) has a fixed set-point and precise water temperature control. The controls are mechanical, and all internal to the compact valve, which is simple to install but because it operates only from a single set-point, lacks the ability to self adjust in certain DHW configurations.

Typical thermostatic and electronic valves need to be installed into the piping system by the contractor, and often require many field connections and thermostats to be hooked up correctly in order for the system to function correctly. Electronic tempering stations are a pre-plumbed unit that only need to be hooked up to hot and cold water and power, avoiding manual connection of the valve and the sensors in the field. This saves installation time and provides a more robust installation. For more information see our product page on the Electronic Tempering Station (ETS).

A tempering valve mixes hot and cold water to create water at the perfect temperature to distribute to sinks and showers. They are typically used in hotels or office buildings, anywhere where there is centralized delivery of hot water. If the water delivered is too warm, scalding can occur. If stored water is too cold, bacterial growth can occur inside the tank. The tempering valve allows hot water to be stored at a high temperature that will kill off bacteria, but then mixes it with cold water to distribute to the fixtures at a lower temperature that will not scald users.

Which Trap Seal Primer is right for you? With so many different types and brands of trap seal primers, it’s important to pick the right one for your projects as not all are the same. MIFAB wants to make that search easier for you.Why are Trap Seal Primers needed in a plumbing system?Trap seal primers are a necessity where floor drains are infrequently used and in areas such as mechanical and service rooms. Evaporation of water in floor drain traps allows sewer gas, pests and bacteria to enter the interior of the building. Trap Seal Primers are installed on a cold water supply line, and react to water flowing in the line to trigger, either by turbulence or pressure drop. Once a triggering event occurs, the primer will release water that is piped to a trap primer connector on or near the “P” trap being maintained.How do I pick the right one?There are four main types of trap seal primers, so it is important to know the differences between them as they each have their advantages and disadvantages. You want to make sure you pick the Trap Seal Primer that will meet your needs. The four main types are: 1. Continuous Flow2. Pressure Drop Activated3. Flush Valve Operated4. Electronic Continuous flow trap seal primers are the original style of trap seal primers. They are typically constructed of cast brass or bronze with a neoprene rubber poppet float on the inside that rises upward as water flows through the primer. Continuous flow trap seal primers do not have any method of screening out line debris. This often results in their clogging and either flowing water continuously, or not at all. The volume of water that they discharge is directly related to the amount of water that continuously flows through them. For these reasons, pressure drop activated trap seal primers have become the selection of choice for specifiers.

If water is stored below 140℉, bacterial growth can occur that can have serious health risks to building occupants. The most common bacteria is Legionella, which has been known to grow in domestic hot water systems, as well as cooling tower water. In order to kill off any existing bacteria and discourage new growth, water must be stored above 140℉ often as high as 160F. For domestic hot water systems this means that the storage tank must be maintained at or above this temperature. However, scalding will certainly occur if water that hot is piped directly to a sink or shower. Depending on local code hot water to fixtures should be in the range of 115-122℉. The tempering valve is installed at the outlet of the hot water storage tank, and its output is then piped out to the hot water distribution of the facility.

Pressure drop activated trap seal primers are typically manufactured out of brass, as are MIFAB’s. The M-500 Pressure Drop Activated Brass Trap Seal Primers can be connected to any cold water line and will be automatically activated when a valve or faucet is on the line, is opened. They are made with a ½” MIP inlet connection and a ½” FIP outlet connection. They have an interior cartridge that seals when the line pressure is in a static state. It only requires a 3 PSI line pressure drop to activate the primer. The opening range for all of MIFAB’s M-500 Series of trap seal primers is 20 to 80 PSI. Even better, there is also no precharge needed which makes cleaning and repairs simple. MIFAB has also made it easier for the inspection of water delivery by strategically placing four view holes to shine light through one side while looking into the other to see the water delivery. The stainless steel sediment filter keeps the primer clean, and because of their unique design, after wear the filter can be replaced without affecting the performance of the primer. The M-500 Series of trap seal primers do not require adjustment (except M3-500-NPB). They are engineered to deliver enough water to serve 3, 6, or 10 floor drain traps without adjustment. Also the “O” ring seals are tested for reliability at a temperature range of -40 degrees to 450 degrees F. All three models are listed with IAPMO and CSA and are tested and certified to the ASSE Standard 1018 and are so marked. U.S. Patent # 6,152,164. Flush valve trap seal primers are installed below the flush valve and direct an amount of waste water discharged from the flush valve into a tube that connects to the floor drain trap to maintain the water seal. Their advantages are that the water used is already consumed by the flush valve operation, and this type of primer has no moving parts. Their disadvantage is that their location is determined by the location of the fixtures which may be too far away from the floor drains to be practical; Many installations cannot use flush valve trap seal primers because the floor drain traps are too far away to be reached by the flush valve trap seal primer. Looking for something Electronic? MIFAB also has that covered! MIFAB’s MI-100 series of electronic trap seal primers are a pre-assembled electronic trap seal primer system programmed to maintain the water seal of floor drain traps. It is made with an ASSE approved vacuum breaker, solenoid valve operated by a timer, shut off valve for maintenance. The MI-100 is engineered for equal distribution of water to all ports. like the M-500 it prevents the backflow of sewer gas, bacteria, and pests from crawling up. For the M-500 it is recommended to keep the trap seal primer close by, anything farther away than 20 feet could be an issue, as the farther the primer is away from the source of the pressure drop, the less likely it will sense it and work. The MI-100 on the other hand can be located anywhere in the building owner to adjust the frequency and amount of water delivery through a timer and stainless steel solenoid valve. The design of these primers is programmed at MIFAB’s factory with standard flush times. These flush times can be adjusted by the operator in order to discharge more or less water to the floor drain traps, depending on the installation and climate conditions. The MI-100 can be installed with a cabinet cover and capable of priming 1 to 30 floor drain traps. It is practical to serve many floor drain traps in infrequently used buildings such as convention centers and sports facilities. Knowing which trap seal primer will work best for you is important, MIFAB is proud to offer all four types and if you need any more information please visit www.mifab.com.
