Often asked: What Is The Purpose Of The Trap In A Condensate Drain?

In short, the fundamental purpose of one of these traps is to use a column of condensate in such a way as to prevent air movement into or out of the equipment casing, while still allowing the condensate to drain away. An improperly constructed or missing trap can cause the following problems.

How does a condensate trap work?

The condensate trap is a device inside a condensing boiler which collects water from the condensing process before it is expelled into the sewer via the condensate pipe. The purpose of the trap is to prevent toxic gases from entering the condensate pipe, and to manage the flow of condensate fluid out of the boiler.

Does a condensate pipe need a trap?

Building regulations require a trap to be installed in the condensate pipe from the boiler. If it goes straight to a gully or rainwater hopper a water seal of at least 38mm is required.

What is the function of the P-trap that is part of the condensate trap?

The P-trap traps solids that can clog the drain or sewer line. The P-trap stops sewer gases from backing into your home through the drain line.

What is the condensate trap?

The job of a condensate trap is to safely collect and release the condensation produced by the boiler, preventing any vapours created during the combustion process from escaping with it. These components vary in design depending on the model of boiler you have, but they are all fairly simple.

Can condensate pipes go soil pipe?

Re: Boiler condensate into soil stack Yes it’s ok but you need to follow the Manufacturers instructions to the letter.

What is the purpose of AP trap in HVAC?

The same thing applies to our air conditioner, but in our case, the purpose of the P-Trap is to prevent outside air from being drawn through the A/C unit. The weight of the water in the trap is enough to prevent this, while still allowing condensation to flow freely.

Do all drains need a trap?

Because of its shape, the trap retains some water after the fixture’s use. This water creates an air seal that prevents sewer gas from passing from the drain pipes back into the building. Essentially all plumbing fixtures including sinks, bathtubs, and showers must be equipped with either an internal or external trap.

What is the point of AP trap?

A P-trap Prevents Odors The curve in P-Trap always retains water. Water is trapped at the bottom of the curve — hence the name. This small volume of water prevents sewer gases from entering your bathroom, sparing your nose from nasty odors and protecting your health.

How do you prime a condensate trap?

When you turn on an air conditioner for the first time, it may be necessary to prime the trap. You can do this by pouring water into it. You can also run the air conditioner long enough to make enough condensate to fill the trap. Try to avoid using the continuous fan setting until the trap is primed.

How much water should be coming out of a condensate pipe?

Typically, it is expelled in around 300ml bursts, so you may hear the water going through the pipe at intervals. The idea behind this ‘burst’ of water, rather than a trickle, is precisely to stop the water in the pipe freezing as it heads out of the property. Shorter bursts of warmer water should prevent this.

Why is water dripping from outside pipe?

The most common water leak from a pipe outside your home is probably your central air conditioner’s condensate drain line. The other means your “primary” drain line is clogged, and you should schedule AC service as soon as possible.
