I'm going to install sub-meters. Not for billing the tenants, but for ease of identifying the offenders/leaks easily. I'm tired of large water bills and the 'wasn't me' from everyone.
I'm getting quotes from a couple of plumbers. But I'm also pricing out the materials, in the event that they come back with atronomical numbers.
I would like to know if there are any plumbers on here who have sugggestions or anyone who have done it thems. I have a 3/4 main meter with 5/8 output. That's pretty typical. After this meter I'm going to put in 3 submeters. What size meters would anyone suggest? Also, what size piping to these meters from the main meter? I was going to branch out from the main meter to these meters, with a 1 inch pipe or 1 1/2 inch pipe. From the meters themselve to the existing 1/2 pipes that run into walls I'm debating 3/4 or 1 inch pipes. Thats really where I'm getting hung up. Don't know if it really makes a difference. These are triple deckers, Ideally you want 1 1/2 pipe size when your feeding an entire triple decker off 1 meter.

-- have you mapped out exactly how each of the units are currently plumbed ??
-- is hot water service common or individual ??
-- often, over the years in single meter service buildings, handymen have done some creative repairs which may have crossed lines.
-- sub meters will create decreased flow volume and pressure.
I would up size meters (as allowed) and maximize downstream diameters as much as possible for good flow and pressures
copper has gone way up and larger meters are exponentially more.
how large is the main coming in from the street to your main meter ?? --67.49.xx.x

Find out if you are liable for T utilities. In CA, LLs are not if the bill is not in their name. So it is best to buy water meters and get rid of your water bill if you can. Pex is your friend in repiping! --201.140.xxx.xx

Presuming that are 1 full bath & 1 full in each unit then you would be fine with running a 1" line from the meter then using 3/4" lines to feed each of the 3 units. In reality this would most likely be larger than you need but IMO it's better to go up a size than to be too small. Before you start you should do a pressure check to see what the income water pressure is.
In my 4-unit buildings, I use either a 1 1/4" or 1 1/2" CPVC for the main. I then tap off of this with a fitting that accepts 3/4" PEX. I use this 3/4" line (blue color) to feed the water heater & to bring the cold water to the individual units. I run a 3/4" line (red color) from the water heater to the individual units. Once I'm near the individual unit I use 1/2" PEX to distribute the water as needed. By using ball valves where the 3/4" lines branch off the main line, I can easily isolate the water for each unit. --71.174.xx.xxx

Mine was 1 inch meter from the city. I ran 1 in line and split to 3/4" water meters. Continue with 3/4" lines to apt.
From the meters I ran wire for digital meter read. Don't have to go into the crawl space to read ;) --174.211.xxx.xxx

The most cost effective is to use Uponor commercial pex piping where run up to each individual suite. 3/4" then install a manifold to go to other fixtures. A water meter can be bought on Amazon. Uponor requires a special expansion tool to expand pipe before fitting is installed. View some videos on You Tube on how to work with Uponor pex piping. --99.236.xxx.xxx

When retro fitting we ONLY use Uponor flexible pex (expansion) home runs to a manifold, no Ts or joints. The labor and faster turnover is much cheaper than the extra materials needed.
We just ise the white only. Put colored tape on the open end to mark hot or cold and to keep the line clean while working.
I hired a plumber to run pex but he did the old fashioned method with clamps and fittings. Cost me $1000 because it took so long. MY guys could have run Uponor home runs in 3 hours. His lines have 20 joints (possible leaks).
Remember every joint is a possible leak.
Uponor can freeze without splitting.
If you have 3 units you only need 2 on meters. Just subtract them from the main bill to know the third aptís usage.
The meters are cheap.
Other: we replace toilets with dual flush. Green is IN and prospects like them.
On normal toilets we install a double flush fill valve. The user flushes but the tank does not refill until someone turns the handle again. These habe saved us a lot of water.

For rentals the Niagara Flapper Less toilet is the best option where the bucket tilts then the toilet flushes complete. Had great result with Niagara Flapper Less toilets which are simple along with no flapper to leak. With dual flush a tenant will push the full flush which a Niagara Flapper Less uses water water with dual flush in full flush mode. --99.236.xxx.xxx

I remember seeing a leak detection system that might be cheaper than submetering --24.101.xxx.xxx
