Regulators should be set to maintain 11" WC with 100% of propane equipment in service (although 50% will work).
Sounds like your LP regulator is NOT working correctly.....could try to adjust it but may just want to replace.
This is not entirely true. The regulator only regulates pressure and not the flow. Correct pipe sizing for the total BTUs at the specific long run to maintain no more than a 1/2" drop on an 11" water column is the standard. This means that your system should be sized such that each appliance, when turned on will not cause more than a 1/2" drop on an 11" water column at the appliance. If you now have a 3/8" regulator, you might add enough to cause you to need a 1/2" regulator, or a 3/4" regulator, or maybe even a 1" regulator. You don't increase the pressure (water column) on an undersized regulator when you add more appliances -- you increase the size of the system and maintain the same water column.
