I had a real bad rotten egg smell at my bathroom sink but only on the hot water side. Very strange as it's the only tap with the issue and happens if I'm on city water or my FW tank. I mixed up a 5 gallon bucket of water and 1/4-cup of bleach and ran it through all of the faucets. Let it sit all day and am flushing it out now. Also ran a bit into the fresh water tank which I'll flush out soon.
Also noticed a bit of calcium build up on my quick connects and 4-way water splitter. Soaked everything in vinegar for the day and brushed them all clean.
And, I mentioned this on my Now or Never thread- but went to the notary to have them notarize our signatures for USPS and domicile forms for transitioning our residency to FL.
And finally, loving the Florida weather.
