Do I need a sediment trap on my gas line?

According to the 2016 California Plumbing Code (CPC), sediment traps are required for all gas appliances except: illuminating appliances, ranges, clothes dryers, decorative appliances for installation in vented fireplaces, gas fireplaces, and outdoor grills. Those are quite a few exceptions.

Does condensate 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.

What does a gas sediment trap do?

Sediment traps are intentionally installed to help prevent sediment in the gas piping from getting into the gas valve or burner area of an appliance and fouling things up.

Do you need P trap with condensate pump?

Yes, if the pipe extends below the water line inside of a pump, that is a trap and yes, if someone adds another trap it won’t work very good. Also, the furnace has a built in condensate trap inside of it, so you need to be aware of that too.

Do you have to have a drip leg on a gas line?

Drip legs are required to be installed in a manner that meets or exceeds fuel piping codes and manufacture requirements for appliances and devices. The drip leg serves as an area within the fuel piping system to protect your appliances and regulators from damage.

Does boiler condensate need a trap?

All condensing boilers require a condensate trap of some sort, some are better designed than others. On the early Junior/Si the condensate trap was susceptible to blockages. The Ri also has a condensate trap but doesn’t really suffer from the same issues as the Junior/Si.

Where do you drain the condensate line on a furnace?

The condensate drains out through a pipe, usually on the bottom of the furnace. Most high-efficiency furnaces also have a secondary drain line that comes out of the flue pipe. This secondary line is used to drain any residual moisture so it doesn’t leak into your furnace.

What is the difference between a sediment trap and a drip leg?

Sediment traps are basically for the purposes of catching sediment and contaminates in a gas line. Drip legs are basically for catching condensate and moisture in a gas line.

What’s the difference between a drip leg and a sediment trap?

Drip leg verses sediment trap Plumbers and some inspectors will often use the terms interchangeably. However: Sediment traps are basically for the purposes of catching sediment and contaminates in a gas line. Drip legs are basically for catching condensate and moisture in a gas line.

Where should a condensate trap be installed?

The Condensation Trap should be assembled in the correct orientation at the bottom of any vertical pipe run installed in any unheated area, such as a cold loft space.

What are condensate drainage traps?

Condensate Drainage Traps | Polypipe Polypipes condensate traps are designed to safely collect and release the condensation produced by your boiler, preventing any vapours created during the combustion process from escaping with it.

How does high pressure condensate flow through Steam traps?

Resultant liquid flows by gravity to the steam traps. As the traps cycle, high temperature condensate flows to High Pressure Condensate (HPR) receiver. Pressure in the HPR is maintained slightly below the lowest steam user in the system to facilitate the flow of condensate from the steam traps to the HPR.

What is backpressure in a condensate trap?

The pressure downstream of the trap is generally called backpressure, and is made up of any pressure existing in the condensate line plus the static lift caused by condensate in the rising pipework. The upstream pressure will vary between start-up conditions, when it is at its lowest, and running conditions, when it is at its highest.

Where condensate from more than one trap flows to the same collector?

Where condensate from more than one trap flows to the same collecting point such as a vented receiver, it is usual to run a common line into which individual trap discharge lines are connected.
