Question: I am presently rebuilding the propane system on my 36′ sailboat. The 20lb tank, regulator and shutoff valve are located in a sealed box (vented overboard) inside the starboard cockpit locker. Some suppliers recommend that a high pressure solenoid shutoff be installed on the high pressure side of the regulator, i.e. between the tank and the regulator. Others recommend that a low pressure solenoid be installed on the outlet of the regulator, i.e. between the regulator and the discharge hose. Which is the correct way and why? Or can it be done either way? I only want to do this job once so want to do it right the first time!
Answer: I’m not an expert in propane systems. What I can tell you is:
- I have never seen a solenoid on the high pressure side. This does not make it wrong, it just means that I have no experience of it. My boats have always had the solenoid on the low side of the regulator.
- Whichever side it is on, however, you need to have one in the locker.
- I would avoid two bottle regulators.
You may wish to get hold of a West Marine catalogue; they have a section on how to hook up a gas system.
