Hi,

My plumber explained to me why I need to have a vertical nipple with a
cap to catch particulates.

I would like to know how many of these traps I should set up? Just
one? A couple? Next to each valve? For each appliance?

Many thanks in advance,

Aaron

I've always put a "dirt leg" close to the connection for each gas
applicance (dryer, water heater, furnace, range, etc. Usually right
before the valve for the appliance.

MC-

As Paul posted, that has been my experience and how I have done
installs but.........in my house the furnace has one, the water water
& stove do not. Owned this house for 30 years & have had no problems
with any of the gas appliances.

I wonder if the "dirt leg", as Paul calls it, is ancient practice that
has no real value kinda like "air chambers" made of a foot or so of
pipe.

I was told years ago that the "dirt leg" was really a "condensate
trap" ...........

cheers
