Hello, i have a basic combustion cannon. and i have had it for a while. and i think it's time for me to try metered propane.
my question is a "dwv" bell reducer Ok to use with metered propane?
i know that you can use non pressure rated parts in a combustion cannon.
but is the use of DWV parts "SAFE"? to use in a Advanced Combustion cannon with meterd propane?
Thank You
Bell Reducer For Advanced Combustion Cannon?
Why not just build a new cannon with coupler/reducer bushing combo instead of the bell reducer. This would give you the opportunity to upgrade to a multigap spark, fan, cam-lock barrel system, etc etc.
DWV bell reducers have a fairly shallow socket depth and accounts for their being shunned on high powered cannons. An advanced metered propane will under ideal conditions be significantly more powerful than a hairspray spray and pray. I recommend doing it right...you'll feel happier!

yea i might just as well build a new cannon,
I didn't see anything on that page that would indicate that bell reducer has a PW rating. The 2" socket in particular looks a little shallow.
Yeah, the pics don't tell the whole story. The 3 that I have all say 429-420, NSF pw PVC1, SCH 40 D2466. Spears manufacture. These are 4" to 2" bell style with a much gentler taper than the DWV reducers from Lowes. The socket depth is 1.380" using my Lyman dial caliper.starman wrote:I didn't see anything on that page that would indicate that bell reducer has a PW rating.

Good luck.
All of the PVC plumbing parts at my local home depot are NSF preasure rated. It is strange because they are all cheaper than the DWV stuff at Lowes. Check out Home Depot it is a spudders dream for SCH 40 Pvc.

You will find almost all PVC parts up to 2" are pressure rated at both Home Depot and Lowes and all 3 and 4" parts except end-caps to not be pressure rated.
They both also ignore 2 1/2" PVC like it was the plague in plumbing....a few sched 80 pipe and parts in electrical.

no, I mean All pvc (the white stuff only not conduit or cpvc ect) is NSF pressure rated up to 4 inch. you have to go to TSC if you want 4.5 inch up to 8 inch pressure rated in my area. It is strange for the lack of 2.5 inch pipe, I wonder why it is not that common.
Highly unusual for the 3 and 4" stuff to be pressure rated at Home Depot and Lowes. Check it again...NSF isnt enough...needs to say NSF-PW and if the pipe is cell core, it isn't pressure rated. What area of the country do you live in?
2.5" is readily available at commercial/industrial plumbing supply houses, where the commercial building contractors buy by the big truck loads.

yes, the 3 and 4 inch stuff is NSF-PW at home depot, not at lowes. My home depot dose not sell DWV.
My Tsc you can buy all the up to 8 inch NSF-PW (it is pretty expensive)
I live in the southern western part of NE OHio if that makes any sense, we use a lot of pipe to irrigate live stock pastures to give constat water supply to the cattle, alpacas and horses, we even have an ostrich farm near my house. Sometimes it is used to irrigate the soy bean and wheat fields, but it is more common to have constatnt water supplies for live stock.

The dominate farm environment there in Ohio may make the difference in how Home depot stocks the stores. The 'burbs are dominate in my area so residential plumbing tends to rule the day.
I can get all the pressure rated stuff I want, just not at Home Depot or Lowes....I wish that were different along with proper support of 2.5".
