Propane gas line

[Frozen23]

My supplier sent 150 ft 3/4'' yellow gas pipe instead of 1''. I didn't check and the line was buried.
Two options as I see it:
- to replace the line which costs $600 with excavation and materials
- to figure out two regulators: one, high pressure, from the propane tank to the riser, another from the riser to the equipment.
I need 250,000 Btuhs max, the 3/4'' at 150 ft can push 175,000 at 11 w.i.c.
The question is the second path an optimal solution?
For how much would I need to increase inlet pressure from the tank to the riser?

What is the brand of csst pipe ? Riser inside or out? Tank to riser length? If where u r can run 2 lb into the building then inside another reg 2lb to 11". With the 2lb reg off the vent run a 3/4" line or larger outside.

Compact First Stage Propane Regulator

The underground 3/4'' pipe is yellow pvc with a Con-Stab outside riser. 125 psi rated. Tank to riser is 150 ft.

10 lb reg at tank loses 7 lbs. Talk with a reg company for a correct 2nd stage reg and should be a lockup type. Need more or less pressure can always change the spring if there not enough adjustment.

You can't always change the spring. There's a limit to that.

Are you talking about running pipe from your second stage regulator to your equipment? If so it can run at 2psi and give you over a million btu's per hour. So you'd just need a 2psi to 7" wc regulator at your equipment.

Lp runs at 11". In some states you can run 2 lbs in a building depends on what codes if any do they use. Post 3 he's using Con Stab to run a riser on the out side the building with is a plastic fitting. Don't think this is a house because he's running a riser on the outside a building. Seems very odd to place a lp tank 150' from any building that only needs 250k btu.

Outside riser to 200K Btus propane water heater is 15 ft and 30 ft to 50K dual oven range, so I am not worried about these distances. Never dealt with propane other than regular installation, so wasn't sure how much pressure do I need to to push 250,000 Btus through 150 ft of 3/4'' pvc pipe. If 2 psi is enough to push the required Btus from high pressure regulator to low, that resolves the issue

It's a house. The above ground tank is moved that far for aesthetic purposes.

Not sure why I typed 7".

Then use 1st stage reg to the house, second stage at the house. If from second stage have 50' with 3/4" for 255,000 btu. Have you figured in any fitting pressure drop in feet?
