Just picked up a electric LP solenoid for my tank and was wondering if it goes before the regulator or after
After as it shuts off the low pressure after the regulator.



Ours is right after the regulator and attached to it, bottom left arrow. Bottom right is the line to the tank and top is the line to the stove and that opening needs to be filled. I took the picture a couple weeks ago after installing the new regulator and fill line and new line to the stove.

I used the old solenoid as it seems to be working fine and is easy to check every couple days (turn solenoid off with burner lit).

The locker is in the side coaming of the Endeavour. We also had the propane tanks checked and re-certified. The new regulator also has a pressure gauge, old one didn't, that helps to see if you have leaks. I also soap tested everything. We turn the solenoid on when preparing a meal and off afterwards with the switch, with light, in the galley,

Summer I'm having a little difficulty picturing the propane locker from your picture. I'm sure it could be the picture but it gives the impression that area is not sealed and that venting might be directed to the cockpit instead of to the outside. In the old days before pressure switches and solenoids we used to sit a propane tank on deck and hook it up to the stove via copper tubing. Back then you also learned to be very careful. Up to this day having a propane tank inside a boat's comparment makes me feel uneasy. I understand the safety measures of having a sealed locker vented to the outside of the boat and would not settle for nothing else. Propane leaks occur more frequently than it would seem.

I don't have a good picture, but the locker (there is another on the other side) is below the second arrow from the left in the coaming and opens to the water side/lifelines, not into the cockpit. It has the required drain in the bottom and the drain is overboard below the rubrail. The lockers were stock on the Endeavour and designed for the bottles. If gas was to escape from the locker out the door it would go down over the side of the boat as the coaming that surrounds the cockpit is quite high, but the drain is also there.

It seems to be a good setup, but the bottles are a little difficult to put in and out, but 10 lbs. will last us a lot of days and then we would swap the bottle from the other side of the boat to the locker. The other locker is the same with a drain, but no lines plumbed to it and we will keep it that way.

Sorry I don't have a better picture handy,

I had figured it was the picture but just wanted to make sure you were safe. Nice boat by the way.

Read the instructions or the literature associated with your solenoid. Some solenoids work on the low-pressure side and some on the high-pressure side. The solenoid on my boat works on the high pressure side. I like that because my BBQ grill Ts into the high-pressure line. When the solenoid is off, it turns off the supply to the regulator, the BBQ grill and the galley stove.

For a couple of years I had the solenoid on the low pressure side. I could never get a very high flame on my stove. Also, my tank would go empty after a couple of months. When I expressed disgust over the low flame, a fellow sailor asked if I had the solenoid connected before or after the regulator. That is when I went back to the worst marine catelog and discovered that my solenoid was meant to go on the high-pressure side. When I moved the solenoid over to the high-pressure side, my flame got higher and my tank now lasts much much longer.
