Propane smell from tanks?

Question

Jmnhunter

i have a ice castle with 2-30lb tanks that has one of those camco plastic propane covers. when i take the top off to look at the valves and regulator assembly, I get a slight smell of propane, doesnt seem constant or strong.

the 2 stage auto change over regulator is only about 3 years old; so i'm not sure if its coming from a "vent" from the regulator-if there is such a thing? I've taken off the tanks and tested them separately and the leak is not coming from the tanks, i've isolated it to the regulator/hoses as I could still get a slight smell with the tanks off even a few days after. So i'm not sure if this is normal or indeed a true leak? I've tried spraying the tank connections with soapy water with no signs of a leak, I did not test the main hose that connects to the regulator, although I did put some new thread tape on that and it made no difference. 

is there supposed to be some slow vent causing a slight smell? Which I suppose would make sense with the heat beating on the tanks all day

If one of your tanks is near empty it may smell stronger as the rotten egg odor they add to propane seems to be really strong at the end. I just ran one of my 100 lbsers out up at the camper last weekend and since it was the first time I started the heat this year I was thinking leak? ?  But once I shut it off and switched to the full tank it went away.  Good luck.

The vent on the regulator does not vent gas. Only compensates for change of air pressure on the diaphragm.

Do a leak test on the whole business while pressurized.

I had a gas smell in a propane line and bought a hand held explosive gas detector from Menards for $20.00. Found the leak on the first pass. Worked great.

I was smelling propane and figured I had leak some where at my home. Called my propane co-op and they came out with a similar tool and we were able to pinpoint the exact location it was leaking. Then it was re-affirmed with some dishsoap and water over the same spot.

      Now that I have a Big buddy heater instead of my old sun heater the only thing I get to listen to out in the middle of a quiet lake all day is the soft warm hum of my trusty FL-18! 😅

      I think if we’re to buy one right now I’d go with either the LX7/LX6 or a helix ice unit. I’ve used an LX7 before and definitely it’s a beast the LX6 is pretty much the same just a bit smaller screen and price tag. 
    • eyeguy 54
      would be fun to have a newer one but I probably would spend the money on more jigs or better rods. 
    • AlwaysFishing23
      I’m still using my fl18, it does the job but I’d like something more advanced and newer. 
    • eyeguy 54
      Not sure what is best. Still using my FL18. Very happy still.

      Which fishfinder is the best for ice fishing in 2018?   Why overall?   What improvements has your favorite made in the past year or two?

      Analysis shows groundwater use is sustainable, but does affect lake  A scientific analysis recently completed by the Minnesota Department of Natural Resources shows that groundwater use in the White Bear Lake area meets the state sustainability standard. The analysis also shows that groundwater use in the area has contributed to lower water levels in White Bear Lake and that multi-year bans on residential irrigation will have a minimal effect on lake levels. A high-level summary is available at mndnr.gov/gwmp/wbl. The DNR also published the findings of the analysis in today’s edition of the White Bear Press. “We’re committed to working with local communities to make sure that the waters in and around White Bear Lake continue to provide their many benefits to the people who live and do business there, now and into the future,” said Barb Naramore, DNR assistant commissioner. “This analysis provides a valuable tool for those efforts.” The DNR conducted this analysis in response to an August 2017 Ramsey County District Court ruling, which directed the DNR to determine whether existing water appropriation permits within 5 miles of White Bear Lake meet the state’s sustainability standard, both individually and cumulatively. That ruling also required the DNR to impose a variety of conditions on existing water permits in the area, including a requirement that communities ban residential irrigation when White Bear Lake is below 923.5 feet in elevation. As part of ongoing efforts to manage water resources in the north and east metro area, the DNR has worked with a consultant to develop a state-of-the-science groundwater flow model. This new tool allows modelers to assess the impacts of various pumping scenarios on lake and aquifer levels over time and distinguish among the relative impacts of groundwater use in different areas. Previous models could not make these kinds of assessments. Using this new model, the DNR evaluated whether permitted pumping within a 5-mile radius of White Bear Lake is sustainable as defined in state law. The analysis confirmed that the state standard would be met even if all currently permitted groundwater users were to pump the maximum amount allowed for multiple years in a row. The state sustainability standard requires: Groundwater use does not jeopardize future groundwater supplies. Groundwater use does not harm the White Bear Lake ecosystem. Groundwater use does not degrade the water quality of White Bear Lake. Groundwater use does not lower water levels beyond the reach of public water supplies or private domestic wells. The DNR used the groundwater model to look at impacts based on four different scenarios: no groundwater use, existing groundwater use, existing groundwater use with a temporary residential irrigation ban, and maximum groundwater use with all permitted users pumping as much as allowed for multiple years in a row. Water levels in White Bear Lake fluctuate naturally. Such fluctuations benefit lake health by promoting the growth of vegetation that provides aquatic habitat and stabilizes shorelines. The model shows that pumping groundwater increases these fluctuations, particularly on the lower end of the lake’s water level range, making the lows lower. While current groundwater use does not violate the sustainability standard, lower water levels, particularly those below 922.0 feet, do disrupt or diminish some recreational uses of the lake. In order to support these recreational uses, the DNR established a protective elevation of 922.0 feet in 2016. With the new model, the DNR is now able to work with the permit holders having the greatest influence on White Bear Lake, to identify potential changes to water use that can help support recreational uses of the lake. Over the next few months, the DNR will meet with area cities, businesses and residents to discuss the analysis and its implications. The agency is working with these local interests to implement a groundwater management plan that ensures continued sustainability. A copy of the technical analysis and other information is available at mndnr.gov/gwmp/wbl. Discuss below - to view set the hook here.

      @monstermoose78   almost time to plan a get-together.
