That’s the craziest water meter set up I’ve ever seen. Lol. I would suggest using it after you water heater. They accumulate a lot of sediment. I’d say use it under your sink or somewhere that feed the lines of the faucet you drink out of. If u use it on the water meter, or at your primary shutoff, you’ll be wasting the life of the filter to filter water for ur shower, tub etc. I work for my local water district, and I’ve only seen one filter system because we have really clean soft water here. But they had it designated just to the sink, that they drank from
It’s called a ‘whole house filter’ for a reason. The idea is to get filtered water for showering, laundry, cooking, etc.
OP, that water line is nuts. I’d get a plumber to install it. I went with Aquasana. VERY good customer service.
Do you know if your water district uses ammonia in addition to chlorine for water treatment? If so, a regular water filter won’t work. Or rather, it will become saturated in about 30% of the quantity it’s rated for. You need catalytic carbon to remove chloramines (the byproduct of chlorine and ammonia), not just regular activated carbon.
