After some more research, apparently the Big Mac Carbonators often include lead in the pumps: https://mmrc.caltech.edu/Procon/%20Pump_spec%20Series1,2,3.pdf In my testing the outside at least didn't test positive for lead (although I had no way to test the internal parts of the pump...) but...

Some minor updates: I checked with coleparmer and they say that all metals used in those regulators are lead-free. I haven't taken the check-valve apart yet, but I did look at the CO2 pressure and it was about equal to the water pressure. It didn't used to be that way, so perhaps my water PSI...

It was from the county health department. They were meeting with parent due to lead exposure and I asked about my keg system and they were interested in taking a look. I suppose kegs are important to health :) I went with the double ball valve with venting device...

A couple years ago I put together a home seltzer/beer system using all stainless steel except for the CO2 regulator. I added a stainless steel double check valve on the CO2 line to try and keep the (acidic) carbonated water vapor from reaching the cheap brass CO2 regulator (which had a Prop 65...

Sorry to bump an old thread, but since I relied on the advice here when building a tap system, I thought I'd share my experience and some lab data in case it helps other people. I built a 2 tap system, one for beer and one for carbonated water. I split the gas between the two systems using an...

Just wanted to post a final update: While the platinum cured silicon hose initially had an off taste, I found that by baking it at 220F for ~3 hours I could significantly reduce it and then baking another 3 hours completely removed it. Most likely it was some residual contaminate from the...

I've got tons of those JG fittings around, but no way to hook them up to my Perlick taps which use 90 degree barbs. Looking around, people say that those Duotight fittings leak on Perlicks due to differences in how the threading is cut. I tried ordering some platinum cured silicon hose from...

I'll see if I can figure out a way to make that work with my existing Perlick taps. I see a few threads on it. Assuming I can work out the parts, that's definitely a neater solution than using hose barbs and lets me use my existing hard tube.

Edit: You mean something like this? Intertap Beer Faucet Shank (Stainless) - Tower Shank w/ Duotight Compatible Barb | MoreBeer I might have to try that. Edit2: "Please note these shanks are not compatible with Perlick brand faucets." Damn it. The line length doesn't matter since when...

How do you do the duotight on the dispenser side? Are you using a beer tap?

According to the product page, Eva barrier is hard tubing for push fittings. Probably fine for hooking up water lines with compression fittings, but I don't think you'd get a tight seal on the tap shank unless you somehow retrofit one with compression fittings. I'm running ~4 feet of tubing...

I converted one of my taps to seltzer using a McCain's carbonator. Unfortunately I'm struggling with off tastes from the tubing interacting with the carbonated water. Initially I tried showing some Bev-Flex 172 by Accuflex 1/4 onto the shank and using a couple of crimp on fittings, but no...
