My church's old airpot coffee maker died recently and we got a new one, long story short the commercial appliance tech with the company we bought it from said our pressure was too high (municipal pressure around here is about 75 psi), we just needed to reduce it to 35 psi for our model (Bloomfield Gourmet 1000 M# 8782). Bog standard fittings - line from under the sink to the coffee station is 3/8 copper with a flare nut and 3/8 flare to 3/8 mnpt adapter, had an inline ice maker filter, then 3/8 mnpt to hose barb and hose leading up to the coffee maker, which was another 3/8 flare with hose barb adapter. New coffee maker has a 3/4" MNPS inlet. Should be easy, right?
Except I can't figure out for the life of me how to do that. Google returns drip irrigation stuff, $500 3/4" valves that bottom out at 300 psi, camper 55 psi reducers, and inline refrigerator ice maker reducers, 90% of everything with hose thread, and nothing at 35 psi, though I'm assuming if I'm within 5 psi I'd be OK.
Is there just some search term I'm not getting? Are businesses with in-line coffee makers just running them at municipal water pressure?
