You need to watch the ones in the kitchen. When you pull out the kitchen faucet the loop under the sink will catch on the push pull values and you could break them.

Push pull valves
 

I would like to have all mine replaced. Who did your neighbor have do the work?

Note that the typical Villages house has about 10 of these shutoff valves. If you have all of them replaced, make sure the new valves are not leaking. Any valve can leak. I still have the original plastic valves, and, so far, none have leaked. I also have a battery operated water alarm under the sinks, toilets, refrigerator, washer, and water heater. You can buy about 6-8 of these alarms from Amazon for less than $100. A slow leak will sound off an alarm in your house when there is one-sixteenth inch of water on the floor. Cheap peace of mind.

they are push and pull shut off valves.

I sort of agree
 

I kind of agree with you, but then look at the cheap crap and crappy installs they are doing. Brand new homes that are not cheap by any means should never be finished with this ultra low quality product. The licensed contractors that build in the first place don't do the greatest quality work considering the way things move around inside the walls when it comes to these valves! A few straps here and there would hurt at all!

I have 17 of these to replace. Don't forget the garage sink and behind the refrigerator.

I ordered these last week: Brasscraft 1/2 in. CPVC Inlet x 3/8 in. Comp Outlet 1/4-Turn Angle Ball Valve. They have a metal ball valve and glue onto the PCVC. I don't trust shark bite - which is the same type of connection as these popup valves. Should you ever need to replace these, the valve body will unscrew from the CPVC "adapter" part of the valve.

Although this video shows removal on copper pipe, the same technique works on CPVC. Pipe is in better condition after removal than if you spin off the valve.
Super Easy Replacement of plastic valve

In case you haven't noticed, no one has ever accused The Village's Developer of being a quality builder. They throw up junk, as fast and as cheaply as they can.

For most builders, "Building Code" is a bare minimum level of professionalism. For TV builds, "Code" is moving target.

Easy Peasy
 

I have replaced all these valves in our patio villa with a shark bite valve. I'm no plumber, but this was one of the easiest DIY projects I've ever addressed. There is a way the valve can slide off of the pipe, but I found it easier to simply use a small pipe cutter to cut the valve, remove it, and then slide the shark bite valve onto the pipe. Be sure to use a braided metal replacement line from the valve to the faucet or you will be defeating the purpose of having a leakproof system.

Shark bites are available at Ace Hardware, but I was able to purchase several of them in a package through Amazon at a much cheaper rate. I've also replaced all of the valves for my neighbor, so I've become pretty proficient with this project.

You used shark bite fittings and suggest you've improved your original installation?

Most real plumbers would disagree.

Mike Scott Plumbing replaced my water heater using shark bite fittings.
I guess they are not real plumbers?

And at least some DIY'ers :beer3:

Its called a accident waiting to happen, cheep and quick to install.

There you go!

If the shoe fits.

Looking at the mechanical design, yes this is an improvement over the original installation.

Looking at the alternative for installing a brass fitting on a PVC pipe, the Sharkbite looks to have a better chance of success.

Looking at the number of post noting successful installations compared to the number mentioning problems, the Sharbite seems to be reliable.

Check out the Brasscraft link I posted above. It is a brass valve designed to be glued onto CPVC.
