Dual propane tanks

[Jking24]

I'm in the process of setting up the propane tanks for my radiant heat and I'm having a little trouble finding this information. I have two 420lb tanks. What is the standard practice for connecting them. I can't seem to locate a first stage regulator with a dual inlet. I'm also having trouble finding a tee for the pigtails. What is the standard or appropriate way to tie the tanks together. A regulator on each tank then tee into the supply line or is their a switch or device that I'm missing ? I'm gonna call my propane supplier and have them come out to check Everything over I'm just trying to get some information in the mean time.

Are they the 120gallon tanks ? Had two of them at one property ... I think they have a regulator for the two tanks.

Depending on your location -- you have to be licensed to hook this up. Also -- in my neck of the woods no one will fill empty tanks without testing for leaks.

I would call the propane company and ask for a price .... I just had a 1k tank installed and lines to my studio, generator and house. 4 regulators ... the labor cost just for the hookup was way less than my plumber (and they sent two guys) ... 4 regulators. He told me the parts price they quoted was less than he could buy the stuff for. And -- they did all the testing and filled the tank w/o any additional cost (I paid for the propane obviously). I own all the tank and lines/ regulators .... they give a warranty.

I’d do two first stage regulators and probably one 2nd stage regulator. I’d run copper from each regulator to a shutoff, then from the two shut offs I’d run the copper to a T fitting. From the T fitting it would run to the 2nd stage. I’d connect it all with flare fittings.

Thanks for the replies. I talked to my propane supplier and he said i need a pol t into a single first stage regulator. So I've orderd one and that should take care of the situation

Thinking about it a bit more -- must have had a fitting "T" before the primary regulator to connect the high side from each 120g tank. It's the smaller tanks with the duel Reg.

The Primary regulator sat under one tank lid --- still needed second regulator at the appliance

You are correct their will be a first stage regulator at the tanks that drops pressure to +-10psi and then a second stage regulator just before it enters the building witch will drop pressure to about 11"wc

If you "tee" two tanks together the pressure and level will remain equal between the two of them. Most people want a "spare" so you need a shutoff (manual or automatic) for each.

I intend to run both tanks in unison. But all tanks have main valves on them so no need for additional valves

Manifold your tanks to the first stage reg. with 1/2" sch. 80. The info your'e looking for is the NFPA Pamphlet No. 58.
