Is trap primer necessary?
Building codes may require trap primers for traps in certain locations or situations, usually those in which industry experience has shown that they are likely to dry out. The most common requirement is for basement floor drains, which are only used when the basement floods.
Do floor drains have ap trap?
Floor drains, much like the drains underneath your interior sinks, have a u-shaped pipe underneath them, called a P-trap. A P-trap serves a few different purposes, but the most important one for your floor drains is to create a water barrier so as to prevent drain odors, or insect issues from the adjacent sewer system.
Do all drains need AP trap?
According to regulations, all shower drains are required to have P-traps. This includes all fixtures connected to a building’s main plumbing system. P-traps are curved pipes installed under showers and drains of all kinds. This pipe really is an essential component in your home’s plumbing system.
What is the purpose of trap primer?
Trap primers are used in plumbing systems to prevent floor drain traps from losing their water seal by evaporation. Maintaining the water seal will prevent the backflow of sewer gas into the buildings or rooms where the traps are installed.
What kind of primer do you need for a drain trap?
Another type of trap primer can flow water from the potable water system to multiple floor drains/traps. This type of trap primer consists of an automatic timer, electric solenoid valve, vacuum breaker, and a piping manifold with valved outlets, which are each piped to a floor drain trap.

Which is an example of an emergency floor drain?
An example of an “emergency” floor drain is one in a toilet room. Trap primers must conform to ASSE 1018 or ASSE 1044 standards – ASSE stands for the American Society of Sanitary Engineering. More recent plumbing codes have added a trap seal protection device as another method to protect the trap seal against evaporation.
How often do you need to use a drain trap?
Bathroom sinks and kitchen sinks are normally used daily; however, floor drains may not receive liquid drainage for months. Without liquid frequently entering the floor drain and trap, the liquid seal in the trap will evaporate over time, and sewer gas will emit from the floor drain.
Does a floor drain need a trap primer?

More common is a primer that is connected to the potable water supply and activates when pressure fluctuations are…
What is a trap seal primer system?
A trap primer (or trap seal primer) is a plumbing device or valve that adds water to traps. The water seals in traps are needed to prevent sewer gases from entering buildings, but because this water is exposed to the air, it is subject to evaporation over time in infrequently used floor drains,…
What is an electronic trap primer?
Electronic Flow Trap Primer is designed to maintain a permanent trap seal in floor drains where wastes or gully traps are infrequently used.
