1995 Lance Squire Water Heater Question :::
Getting ready to go full time in Aug and my water heater pilot tube stays burning along side the main burner tube. The pilot is burning yellow and the burner LP blue... Is this a problem?

The Pressure Relief Valve is a safety valve.......opens on high temp and/or high pressure.
Leaking when on-board pump is in service......needs replaced
Sometimes they will weep when heating the water. That is due to loss of air pocket in top of tank. Water swells when heated and the air pocket allows for this swelling without an increase in pressure (water can not be compressed so without the air pocket pressure inside tank increases causing PRV to weep)
The air pocket is normally established when first filling water heater. But over time in use the air pocket can be absorbed into the water.
So after you replace that old crusty PRV and you find it weeping when heating the water.....
Turn off water supply
Open closest faucet hot side to relief pressure
Open PRV via lever
When water stops flowing out let PRV snap close
Close faucet.turn on water supply
Think that is what your old manual was referring to....establishing that air pocket
