in Domestic Hot Water

for the past year or two I’ve been replacing wells and aquastat on various hot water heaters no matter the source of domestic water. I just left a job that I replaced these a year ago, I replaced again! Any one else?

    say again? My guess would be the client doesn't like cold showers?

    I believe it was just a harmless joke at the pleonasm overlap

    dezincification? Check the ph of the water. Change to stainless or tin plated wells

    Have you tried a different brand/manufacturer? There might be a foundry issue with the emersion wells you are using.

    China sourced materials are known for not passing code. Had to reject a thousand feet of 1" black iron, that would not thread, too brittle and went to US Steel which worked; rejected Chrome shower arms also; could feel the thread grooves on the inside pipe wall, also weighed less than code approved. No one verifies import quality anymore. I could go own. With any well water system i use Stainless Steel for acidic water. Buy American no longer means made in America. John Deere just built a plant in Mexico. I have 30 year parts in my warehouse that will last 4 times longer than cheap imports. I'll bet most new materials will not meet code specifications today.
