What does a boiler condensate trap do?

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.

Does a boiler condensate pipe need a trap?





The boiler should never be operated without the condensate trap in place, as it prevents noxious combustion gases from travelling down the condensate pipe.

Does 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 plastic pipe from boiler?

The condensate pipe is used to drain all the excess water produced from the condensing process in your boiler. Since the water, aka the condensate, is mildly acidic (that’s because it is a by-product of the condensed waste gasses), it needs to be drained through a PVC or ABS pipe.

How do you empty a condensate trap?

Quote from the video:
Quote from Youtube video: The condensate trap is constructed of two pieces. The lower clean-out. That can be removed you will have some water in that clean-out. Clean out the bottom drain. Cover.

How do you drain a condensate trap?





Quote from the video:
Quote from Youtube video: And this trap has water right in the bottom here. So we're going to go ahead and see what. Happens. So now it's allowing all the condensate. In this pan to drain out properly.

What does a boiler condensate pipe look like?

Look under the boiler to see if there is a plastic pipe – It’s usually white and around 20mm (about ¾”) wide. The pipe should run to the outside of your home and should always run into a drain. An example of a condensate pipe is shown below. The condensate pipe is the diagonal pipe running along the side of the house.

What is a condensation trap?

A condensation trap prevents condensed water from running back down the duct towards the fan.

How much water comes out of a boiler condensate pipe?

A typical hour-long operation of your boiler may produce around 2 or 3 litres of the condensate water waste. This waste generally gets released in 300ml increments, and is often the reason you might hear water travelling through your pipes during intervals.

Why is water coming out of my condensate pipe?



A boiler condensate pipe dripping could be due to a cracked heat exchanger. This can lead to mains water or the system draining into the condensate pipe and the hot water can cause the pipe joints fail. Installing a new heat exchanger should resolve this.

Where does boiler condensate pipe go?

Where should a boiler condensate pipe go? The HHIC states that: ‘When fitting a new or replacement boiler, the condensate discharge pipe should be connected to an internal ‘gravity discharge point’, such as an internal soil stack, internal kitchen or bathroom waste pipe such as sink, basin, bath or shower waste.

What are the pipes under my boiler?

You will find seven pipes attached to the boiler: A gas supply pipe. Mains cold water inlet. Hot water outlet.

How do you resolve common problems with condensate traps?



Depending on the type of trap in use, it can be blown dry with every cooling cycle leading to more problems inefficiency. The best way to resolve these problems is by contacting your HVAC technician to have the condensate drains cleaned and flushed.

Does the condensate trap need to be primed?

Condensate trap at furnace must be PRIMED or proper draining may not occur. The condensate trap has 2 internal chambers which can ONLY be primed by pouring water into the inducer drain side of condensate trap.

How do you prime a drain trap?

Quote from the video:
Quote from Youtube video: And you're still noticing an odor you can try another mixture with just about a cup to half a cup of bleach in the gallon of water and repeat the process. And that is how to prime your drain traps.

Should air be coming out of my condensate drain line?

Generally, an AC condensate line should not be releasing air. If it does, it implies clogging in your drain line, requiring you to clear it before it causes further harm to your AC system and home.

Does a furnace condensate drain need a trap?



All condensate drains go into a trap. The condensate trap is absolutely mandatory for a high-efficiency gas furnace. Since the drain taps into the exhaust system, leaving it open to the air would allow for a potential exhaust/flue gas leak in the living space, which is a big no-no.

How do I know if my condensate line is clogged?

Signs the AC Drain Line is Clogged

  1. Musty, moldy smell near your indoor unit or in air from the registers/vents.
  2. Standing water near the indoor unit.
  3. Water damage in areas near the indoor unit.
  4. AC system is not cooling your home.
  5. AC system shuts down or doesn’t turn on.
