Plumbing - Part Number Search

[In My Garage]

For those more experienced than I am, I am looking for the part number for the following item.

I have a main water line shut-off valve on each side of my city's water meter with a 3/4 inch copper pipe. The valves are coming up on 28 years old and I shut them off when going on vacation, especially in the winter should the furnace break down. It is time to replace the cartridges or to at least clean them up for smoother action and to replace the seals.





I am looking for cartridges to save time instead of replacing the bibb washer and O-ring on the shaft. The city needs to replace my water meter after 25 years and the first inlet valve can leak past the O-ring at times, so I am asking them to shut the main valve off. And to save time when the city replaces my water meter, I'd like to replace the cartridge instead of cleaning up the valve and replacing seals.


I got one of these at the local plumbing supply, but it is likely for taps with a 1/2 inch line as the bibb washer is small. An EMCO 1057.



The difference in bibb washers. Left: 3/8" bibb washer on the EMCO 1057. Right: 5/8" bibb washer on my EMCO 3/4" shut-off valve.



My EMCO used with the 3/4 inch line has a much larger bibb washer and backing plate (the rest of it is the same as the EMCO 1057). I've already refurbished the second shut-off valve with a new bibb washer, O-ring and plenty of silicone grease (keeps my valves running forever).



So now I am looking for the EMCO PART NUMBER for the above "original" valve because the EMCO 1057 cannot take a 5/8" bibb washer.

Since the city is turning the water off anyway, is there any reason you aren't just replacing the old valve with a new quarter turn ball valve? It would be relatively quick and easy to solder in place. It will flow better, and is much easier to turn off because it doesn't have a seal to compress.

Nice to have a quick quarter turn shutoff if you have a leak and the only one home is a spouse, friend or child without a lot of wrist strength. Just seems like a good choice.

I would change out the valve to a quarter turn when they shut you off. way better than those style valves you have
and, on top of that , newer washers don't seem to be as good as the good old fashioned ones were. perhaps its due to the country they are now manufactured in .

Thanks but I'll stick to what I have and I do have 3 quarter-turn valves already in my home that hardly see much action and what I do not like about them is there are sealed and not rebuildable.

It looks like I found my valves at EMCO, the whole valve and not the cartridge, but that is OK. I'll just uncrew the cartridge and insert it into my valve that are already in place. Saves me the trouble of soldering in new ones. Plus with the city contractor installing the new water meter, I am short on time and two cannot work in the same area.
