PushConnect fittings long term reliability v/s PEX Clamps

I am new to plumbing etc and I am trying my level best to put as robust a system for my new softener.

From my pressure tank to the softener input I am trying to do 1 inch. I have bought the following Pex A pipe

https://www.heatlink.com/product/pureli ... pex-tubing


In my current planned setup I am including following fittings

1) Horizontal - Right at the out of the Tank - A Sharkbite brass 1 inch FNTP to a 1 inch Push to connect ( PTC) . approx 6 inch long pipe into PTC

2) at the end of that 6 inch long pipe there will be a 90 deg bend to take the pipe vertical. Pex brass fitting , Clamps on both end

3) Run the pipe vertical for approx 1.5 feet then add a Tee . I bought a Sharkbite brass crazy heavy (all side PTC) 1 inch in and 1 inch out vertically and 3/4 inch horizontal where I will connect my existing 1/2 inch copper pipe ( for kitchen sink and garden water) somehow

4) the vertically going 1 inch pipe will require some more 90 deg bends ( perhaps 3) before it reaches the softener. All are pex brass fittings clamps style

5) Into the softener there is SharkBite Brass 1 inch FNPT to 1 inch PTC . FNTP is on sofenter side and the 1 inch pipe goes into PTC side.

6) Somewhere in this goes a Ball valve. I bought that the Pex style to be used with Clamps not the Sharkbite PTC style

With so many Sharbite Push to Connect fittings in this small setup, will you be concerned? Reliability is most important for me. Do SharkBite Push to connect are more prone to getting disconnected due to stress etc compared to regular Pex fittings that uses Clamps?

I am not a plumber but I really worry that open will be the “aluminum wiring” of the plumbing world as the plastic degrade inside the wall and leaks spring up.

Also, I dont know what im talking about and could just be ready for my rocking chair, porch, and broom to yell at kids to get off my lawn.

I've never seen a professional plumber use PTC fittings and I wouldn't. I don't have evidence but I don't trust them.

OP: why 1" into the softener?

Every pex system has an active class action lawsuit, including the holy grail, Uponor Pex A.

If you're really worried, consider ProPress copper fittings.

I have PEX and when the plumber came to my house he used the crimp rings instead of the push to connect or shark bite

When we reno'ed our place just over a decade ago, all the plumbing was replaced. I insisted on copper and we approved the quote for the whole reno. We had to move out but I was on site every day and so noticed the plumber installing pex. Big fight with the GC as they had forgotten my demand and, of course, the quote we signed was silent on the material but the standard these days is Pex. I had to choose between several thousand more - and delays - or yield. In the end, our compromise was copper for drinking water and pex for everything else and I hate the fact that my house has Pex and regret that I didn't just swallow the delays and the extra $ or at least also gone with copper for hot water. Retrofitting now would be brutal.

Yup. I have yet to see a pro use anything but.

One is used every day all over the world, one is sold at home depot for diy.

There's no reason to use sharkbites on that install OP, just go with pex. The softener tanks might be jarred; can be moved....that could be a disaster with a push connect fitting. The pex crimp connection is far more rugged, I have seen pex leaking in a sharkbite because the pex pipe was curved and not securely clamped.
Why would you consider push connects, don't have 1" pex crimper or having trouble finding NPTF threaded to 1" pex fitting?

Thanks folks for inputs. I always find rfd helpful
First - why 1" - Because my softener provides connection in and out for 1 inch so why not bring 1 inch pipe from pressure tank to the softener? I have got 2.5 cubic feet softener and in general pressure wise good to have 1 inch into softener.

When I went shopping, I could not find many 1 inch fittings so I just bought bunch of these sharkbites but then some research showed me that sharkbites to be used only for places where Crimp/Clamp tool can not reach. I thought of doing a double check at some other plumbing forums. I normally check on rfd as well. Lots of good folks here too even though they are not professional plumbers.

The softener has 1 inch FNTP end point and it came with a flex connector which has 1inch MNTP on one end a Push to Connect on the other end. That initially gave me the idea that I can go all other fittings PTC as well.
I heard that these flex connectors are good to absorb some pressure etc. Will it be just OK if I use a 1 inch MFTP and pex connector on other end and connect pex pipe this way into the softener ?

Another issue is that in between the pressure tank to the softerner, I need to do a T and supply unsoftened water to my kitchen . Kitchen existing supply is 1/2 inch copper. I am having difficult as to how to go from 1 inch pex pipe to 1/2 inch copper pipe. Any thoughts?

1" is always better but it will provide you very little advantage in that short of a run if the rest of your system is 1/2". If 1" poses any installation challenges, I don't think you'd be losing anything by sticking to 1/2 or moving to 3/4.

IF the Sharkbites will be always visible (ie not inside walls) there is no reason you can't use them (other than "it's not what the pros do"). As long as you can inspect them every couple months for signs of leaks they should be fine.

That being said using PEX crimp (NOT clamp) fittings will be a better setup. You can get 1" pex pipe and fittings and crimp rings at Home Depot. They do now have the expansion style (pex A) but the tool for that is still very expensive. You can get the crimp tool from Amazon for about $150 (even comes with pipe cutter).
