Hello All,

So I've recently purchased an older house, and working on some renovations...

Some of these renovations is to fix some plumbing items (Leaking shut off valves, etc.)... My plan was anytime I replace or fix something, to use PEX and SharkBite fittings..

As I was taking a closer look at the house plumbing I noticed the main supply line coming into the house looks to be a one inch pipe, but then right at the main house valve, it decreases to 1/2 inch pipe for the entire house.

I'm far from a plumbing expert, but isn't 1/2 inch pipe a little small for an entire house?

Thanks,

Yes, that is small for the normal home supply.

But often found in older homes, they had limited supply, and less needs back when.

When you decide to upgrade, a 3/4 size, or more would serve you better.

That makes sense, and is what I assumed...

So then, I would need to get the city to shut off the water to the house to change the main valve, and increase the supply line size, What would be the recommendation, at this point then? Like I said, At the moment I'm using PEX and SharkBite connections on my repairs, Can I use the same from the main supply line itself? Or should I get a new Valve installed on the Copper line, followed by a 1 inch copper line into the house, then migrate to PEX at that point?

I'm not a plumber, I'm in the U.S., and my home is not that old. Shouldn't your home have a shut off valve on the property? It should be outside so there is access from the property. Here they are all at the corner of the property next to the street/sidewalk. Usually a metal or plastic cover.

Don't you have a shut off on the 1 inch line in the house?
Hello,

Yes, I do, so the one inch supply line comes up from the floor, to a main shut off valve, that it's 1/2 inch pipe from that valve to the rest of the house... So I believe I would need to replace that whole valve since it's 1-Inch input and 1/2 Inch output...

Hello,

Yes, you are correct, there is a outside valve on the properly somewhere, but normally the city needs to turn that off as the actual valve itself is down about 7-8 feet, if not more..

Ayuh,....... Usually, valves are straight through, the same size,.....

Are you sure there's not a reducer on that valve to 1/2",..??..??

If so, remove the reducer, 'n switch to pex 3/4" or pex 1" there,......

Otherwise, have the water turned off at the street, 'n put a ball-valve there, 'n switch to pex,....

Here's a Pic of the valve;

Ayuh,..... It appears the 3/4" copper pipe goes into a compression fittin', to pipe thread adapter, the valve screws onto that adapter, then there's a 1/2" to 3/4" bushin' reducer, into which is screwed a sweat fit to pipe thread 1/2" adapter, 'n 1/2" copper beyond,.....

I'd still replace that valve, with a ball-valve, as ball-valves are less problematic,....

Bondo is correct. Me I would have the water co. shut off at their shutoff valve ( they have one to discontinue service incase of no payment), Then cut that off before the valve, and install a new BALL valve, then have the service returned.

Then "pex" it from there in.

Can you interrupt the supply for all this remodeling?

That's a lot for that valve. I'm sure you can get it off ebay, menards, home depot, or lowes for about half that, (not sure what you have in Canada or what shipping is).

I would check your local government or water companies site. I saw one of the other provinces up there lets you borrow the shut off tool for free, or they charge over $100 to have someone come out and shut if off.

Exactly.

Holy crap, you want a brass valve not a gold one.

Do shop elsewhere for that.
