Which Pex Expander Tool to Use?


Hey guys,


The wife and I are ready to start our next house remodeling project. With this house, I am going to use the pex expansion system. When I started my last house 8-9 years ago i was told I needed to be certified. Now the inspector says go for it. I have watched a lot of videos and ready up on it but still have a few questions:


1. Which expander to use? Money isn't an issue, the right tool for the right job. I only see the Uponor tools used. I see the Milwaukee tool being used a lot. M12 or M18?


2. Where do you get your supplies. I want to stay away from big box stores.


3. Do you use plastic or bronze connections?


4. Can one pipe cutter cut both 1/2 and 3/4 or do you need one for each size?


5. For a 4,500 sq ft rambler that will eventually have four baths (3 showers, one 1/2), would you set up as a home run system, or just lay out like normal copper? The whole house is going to be rehabbed and I have wide open access to 3/4 of the basement currently.


Thanks for all the input.



Brian

Re: Which Pex Expander Tool to Use?


1) I don't use the expander type, but using a name brand associated with PEX is good. Uponor is good. Milwaukee may be a bit more pricey. M18 is my choice, as the batteries are interchangeable with other tools.

2) Why? Products are the same, and you may even find it on sale. Don't exclude any source when shopping.

3) I like bronze, but have not heard of any problems with the plastic.

4) A pipe cutter can cut most any size up to 1". https://www.homedepot.com/p/Apollo-1...C001/301573771

5) Always make 3/4" home runs, then turn up to the application with 1/2"

Long home runs cost more hot water as you have to wait at every outlet.

I would still prefer home runs if you ask me. Pressure balance and individual serviceability and control-ability is nice.



I am looking at in place water heating for the long runs.

What about a bathtub ? You say 3 showers, as in just showers or tub/shower combo - you need at least one bathtub of course

I think recirculating pumps for demand will preclude any cold water plugs that are experienced in long runs, but the larger advantage is the water volume is not disturbed to a great extent if someone is showering and another flushes a toilet.

I use Propex. M12 on 1/2 & 3/4 and M18 on 1" and larger

I never use bronze, except when soldering transitions from valves or copper mains. Plastic is my fitting choice

Standard pipe layout with a recirc line on the hot.
If sized correctly, a regular pipe method will do fine- always has. I see no great benefit to manifolds.


Thanks for all the input.

That is good to know. I have always been leery of putting pressure on plastic for fear of splitting it. Thanks.

Re: Which Pex Expander Tool to Use?


I was amazed at how much pressure these PEX (and sharkbites) would hold.

Re: Which Pex Expander Tool to Use?


Thanks for the replies thus far.


Also, help me understand the different types of the pex hose itself. When i went to my big box store, they had "Pex A" as the expansion pex. Doing research, i am seeing ProPex being mentioned. Are these different "types" of expansion pex or different "brands". If I were to go to supplyhouse, what exactly would i be looking for to install 1/2 and 3/4 hot and cold in my house?

Re: Which Pex Expander Tool to Use?


I have the Dewalt expander, bought on sale $225 bare tool with case and dies. Had several batteries and chargers so bare tool was the cheapest for me. Works great, re-plumbed a rental, a flip, and a small commercial building so far. Much easier to use than crimp tools up between floor joists or confined areas.

My local Menards carries sioux chief brand fittings, both poly and brass as well as the A-tubing, always worked fine for me. Pex-A is more flexible and easier to work with, it's required for expansion fittings but it can be used with crimp rings too. Expansion fittings are less restrictive because they're larger internally. Crimp fittings insert into the pipe so are naturally smaller than the inside pipe diameter, inside diameter of fittings is even smaller yet.

Home run is great for pressure balance, I like having minimal fittings in each run and individual shut off is convenient. But, home run install burns through a lot of tubing and it can take a lot of room to route the multiple tubes to the manifolds neatly. I installed a manabloc in a friends house a few years ago, makes a neat and convenient installation, but took most of a 12' wall in the utility room to sweep all the multitude of tubes into it so it looked nice.

3/4" is overkill for most home run applications, you're only serving single point of use. Same length of 3/4 pipe holds over twice the volume versus 1/2" pipe, all that cold water has to be displaced when you turn on a hot faucet so the wait for hot water is twice as long.

We are a larger mechanical contractor and are now using all Dewalt, made in USA. So far after a year everything has gone well. We have 3 20 volt ex panders and 3 20 volt copper crimp tools.

Re: Which Pex Expander Tool to Use?


I just bought the Dewalt 20V expander on Amazon and all the Uponor (ProPex) supplies at supplyhouse.com.

If there are better places to shop, let me know.

I'm about to start my own re-plumb retrofit on a 75-year old house with 1/2" mains.
