R/O water smells skunky

[Rogue951]

I'm in east van and I average 16ppm. My membranes usually last a few years, usually I change it out of age rather than use. Same with the prefilters. easily 6 months between changes.
except this summer a few houses in my area were torn down rebuilt with water main work and I've noticed the sediment filter change color so I've swapped them out faster. Water also smelled a little different but nothing alarming.
Maybe you had construction in your area to cause a spike in impurities?

We're really lucky out here never realized it till I saw the value's of other places.
