Should I use 3/4" or 1/2" valve


Hi all

I am new to site and would like to say thats in advance to all that help/comment on any of my issues

Let me jump right in. I am redoing my bathroom. I gutted it rigth to the beams the easy part is over. I probably should have did a little more research to see what i was getting myself into but anyway here i am.

I decide to do A shower tower either a Grohe or hansgrohe. My question is.
I have a 1/2" water feed can I use a 3/4" valve or should I stick to units with 1/2" valves. My water pressure is around 80psi.

I am looking at the
Grohe - Aquatower 3000

HansGrohe Lift 20

Thanks
Tony

Use a full port 1/2" ball valve. 3/4" would be a waste with 1/2" lines. I am not 100% sure but you might not have enough flow (gallons per minute) with 1/2" lines. Those type of showers reguire a large flow rate.

I second what Paul said--Those units need a 3/4 inch feed line. You will be very -very sorry if you don't run 3/4 directly to the mixer.

Thanks for you replies

I am really disappointed. I would have liked to have the body sprays. Are there any alternative methods, short of running new lines that would enable me to install body sprays(The bathroom is on the top floor I have 3 plus a basement and I really dont want to go thought all the trouble of running new lines from the basement to the top floor). Should I just install a shower head with a temperature and volume control and call it a day.


Thanks
Tony
