I put a new gas valve in my water heater but now the pilot won't
I must have gotten some crud in the jet when I had the lines
I have a set of small drills for cleaning welding torch tips but
before I go drilling into the jet I'm wondering if any of you know
what size the hole in the pilot light jet for a natural gas water
Jet sizes vary according to a host of variables - gas pressure,
material, height of pilot flame, et al.
Try blowing it back with air and if that fails just buy a new pilot
jet for a few $s. Most just screw out.
Normally, the tubing from valve to pilot light needs
to fill with NG. This takes time to purge the air
out of the pilot light tube.
Do you see deflection in the match flame when you have
the 'pilot' button depressed? That's air, not NG.
Be patient, it'll light.
If you don't see deflection in the match flame, then
you get to troubleshoot.
How could that happen? Why is there crud in your water closet?
Try bleeding the air out of the lines first. That's the most common
start failure source. Be patient and it will finally give you a pure
stream of nat gas which will ignite.

In addition what the other guys said about bleeding air out and
cleaning the jet, some, but not all, units have an adjustment for
pilot flame size. The original water heater docs should have details
if so equipped. We usually stuck one of those big manila envelopes on
the side and stuck in the directions. I know I had to bleed my new
replacement heater for what seemed like hours before it lit off, was
probably more like 15 or 20 minutes I leaned on the valve in "light"
position before it finally went. There's not a lot of gas passing
through that jet per minute, after all. I had probably 20 feet of
pipe to clear to the meter shutoff, too.
For orifice cleaning, I use either the 61-80 number drill set or a gas
welding tip cleaner set. Just pick one that fits and don't try to
drill things out. You might tape a narrow strip of tissue paper to a
stick and see if there's anything passing through the jet. A squirt
of bubble solution might work for that, too. If you haven't done that
to your pipe joints, you might do that before putting things into
service. Nothing like a slow gas leak to ruin your day.

One of my nice neighbors let me connect my plumbing
to their hose bib for a few hours so I could flush
toilets and wash hands while replacing the pipe
to my water meter.
The first time I connected, *hot* water came out
of the 'cold' water tap! I was chagrined to discover
that I had connected the hose to the wrong valve
and was back flushing the water heater into it's
So it *is* possible! :)
That's not a surprise I'd like.
However, until Monday, any hot water would have been welcome here.
Hey, they shut our power off again last night, this time on purpose.
Apparently they had to do some work on a substation. This is getting creepy.
I went from 'what the....?' to 'DoH!' in an ohnosecond.
I bet! That would have been difficult though, without
the 'Cousteau' model water heater.
We'll get you into a nice little 4 cylinder NG cogenerator yet!
"Ohnosecond" I love it!
People don't seem to realize how much it costs to operate a small NG
generator. I hear they shit bricks when they get their first bill.
A 36kV genset takes 500,000BTU/hr and NG gives 1,000BTU per c/f.
Methinks Ig has the right idea with diesel gensets.
Small gasoline genset, evocative pic, wot?
