Failed Regulator Troubleshooting

In this video I change a regulator that got hung up, and was causing excess pressure to build in the line. This higher than normal pressure was preventing the gas valve from opening properly. Its very important that proper gas pressure is maintained both while the system is operating and while static. I put a follow up clip, showing that the other regulator also failed almost exactly one year later.

This video just saved me from having to pay big money to replace a pool heater. Turns out the regulator was letting too much gas into my pool heater and the valve would not open. I backed the screw off a few turns and now everything works! Thank you.

It's seems like when a main regulator fails (L.P. or N.G.), it causes problems with the rest of the regulators in the system. I'm a professional plumber, and a manometer doesn't lie. This is a VERY informative video. Thanks bro, well done.

All regulators are set when running not static, so begin there. The 325 Maxitrol Regulator had an indoor Vent Limiter installed, NOT CORRECT. It requires an Outdoor Vent Protector to prevent rain from entering. The Itron Regulator should have been rotated by loosening the two bolts and facing Vent downward to prevent rain entering as well - DON'T USE A BUCKET AGAIN.... And finally, did I see brass nipple on a gas line on the second unit, that isn't what we see on gas lines, around here...

two things wrong with the set up no sediment trap because trash in the line from thread oil or sealant got in regulator and prevented lock up and the Maxitrol had the vent limiter still installed you must cover it or remove and install a outdoor vent cap on it I have run into several jobs where the gas line installer had put indoor vent limiting regs outside and water and bugs get in the vent limiter cap and block it or it gets installed vertically and reg wont function correctly either. I could see right away when you connected you monometer I noticed the pressure kept climbing that's a sign its got something in the seat of the reg. good video.

Dam - When I saw that inlet pressure initially, I thought you must working with propane! Crazy for natural gas.

Shouldn't the vent on that new regulator point down?

[TVwatcher-icne]

Great video. I wish we could have seen what failed inside. Should there be drip legs on those lines before the regulators?

I think my regulator plunger went bad outside natural gas. It's been in the 20 degrees, , , for the past 3 or 4 days. It's getting plenty of gas pressure to the regulator. But nothing's making it through the plunger. I think the regulator went bad?

I only have the first stage regulator, a MEGR 1122H-AAJ which i used when the tank was about 11 feet from home and everything worked fine! I recently moved the tank 90 feet from my home and that's when I noticed the low gas pressure! I had my gas supplier serviceman check my gas connections as I was smelling gas (I have congestive heart failure from Agent Orange and as the effects worsen I am not as strong as I once was so the joints weren't as tight as need be! I used 1/2 gas flex to 5/8 cooper the last 4 feet to home! Is there a chance I will need a secondary regulator the supposedly gas company serviceman didn't mention! I will admit Iwas a little suspicious of him even though he drove a truck with my gas company logo the reason for suspect he claimed his normal work truck was in the shop SO he needed to use my tools, joint sealant and teflon! I really think I need another gas supplier!

getting clogged? maybe system needs a drip leg?

remove a 250 gal tank farther from home but after move my gas pressure on stove in other words stove flame is very low same regulator only difference was 100ft new gas line what could be the cause?

hi Sir, can a medium sized gas regulator power 5 pcs of Laundry Dryers? ( 15kg load size dryer)

[mist]

my gas guy just told me they can stop working if a spider or bug gets in the little hole you see there. he said cclean it out oncce in awhile with a pipecleaner.

I had a Gas Meter replacement recently and the Regulator and Gas Meter box was changed. The Tech did not check any gas pressures before or after, is that fine? Also what’s the symptoms of too much NG pressure coming into a house or is this not a issue with how much pressure is provided in the service lines? Also what’s the sign of a fault regulator? Thanks for any advice.
