Which pressuretrol??

Dave0176

Which one is better the Honeywell PA404A1033 or the L404F1367. I know oems use either of the two just wondering which is a better unit. I can tell you this, with a bit calibration I can get a PA404 spot on. Just wondering got a job coming up and want to use the best stuff.

Wow guess I asked a hard one here 60 views and not even an opinion...........

I have an opinion but I'm not a Pro. I believe the PA404A is more reliable, once you get the pressure calibrated.

If I had a choice I'd choose neither.
Seems like they can't even get the components straight anymore:

I like L404 better.
Don't have to open it to see what's going on.
It has a bigger diaphragm, so more surface area makes me think it's more accurate and durable.

I have bought new PA404 and there bad out of the box.
I keep a 1/4 x 6" nipple in my bag just for testing pressuretrols.
If I set it to 1 psi and I cant get it to click by blowing into it, i replaced it.
Some times manually working the switch frees it up.

My opinion the PA is the cheapest piece crap pressuretrol. I've found too many broken.

Not a lot of options with pressuretrols. Does anybody make them other then honeywell?

Thanks a bunch guys. I too have found the number boards on the pressuretrols and vaporstats to be useless, I need to set them with a low pressure or water column gauge and leave em be.

So for the pros, you go to all this trouble to set these devices properly, how often do you come back and find someone has messed with them?

If it’s always me doing the services, I never find any issues.

They should never call anyone else when they have you on the job.
