Mastertemp 400 heater problem

[JoyfulNoise]

Centerpoint Gas says "If you are requesting a meter upgrade for a generator or pool installation, the generator or pool heater must be installed and regulated."

They are the gas supplier so they operate under the rules they establish and the equipment they provide. However, your pool heater operates as a low pressure appliance (~ 7-11” WC dynamic gas pressure and 400CFM flow rate). That gas flow can be provided at low pressure (~12-14” WC) or high pressure (1/2 psi) at the meter.

I would have the gas company send out a technician to look at your setup and give you advice on what is needed. You have a very short run from the meter to the heater and you can easily be supplied with high or low pressure gas. The only issue is you would need to add the appropriate regulator at the heater to drop the gas pressure down to what is required by the appliance. All the appliances in your home are low pressure as well so you would need an additional regulator on the pipe that goes into your house.

That is fine. There will be a regulator between the gas meter and the house service.

Just for clarification, the meter is only 5' from the heater. The line T's before going into the brick and branches off to the Heater.
Plumber said I need a regulator at heater and also for the house.
Plumber has to pull a permit before Gas company will come out to install larger meter.
$90 for permit (Houston), $$ for Plumber and $350 for upgraded Meter by Centerpoint.

That is correct. The gas company only changes their equipment. You are responsible for everything else. Whoever installed the pool/pool heater did not do their job correctly. They should have checked the meter for its flow rate and then had it upgraded as part of the pool build / heater installation.
