hello: the minimum down diameter is 3/4. you need an exclusive descent only for the water heater and another descent for the cold water if you feed a kitchen bathroom and laundry make it 1 inch and down drifts with 3/4 to the bathroom you place ll.p of 3/4 and follow in 3/4 until the shower set there is only half a reduction and you feed bidet sink sink backpack and shower box connections in half greetings
Of course the issue is that I can not modify the drop of the tank, everything is already 1/2. I think it would be best to continue with 1/2 and put a pressurizing pump.
Now the question would be, if I leave it with the 1/2 descent down to the bathroom (until I can put it 1 ". And I put 3/4 in the bathroom the flow will go down a lot?.
I don't think, if you always had a 1/2 drop, the flow restriction is already there. But if you are going to do the bathroom again do not make the mistake of doing it with 1/2. All 3/4 and 1/2 exit to the artifacts.
If you use average pipes in the bathroom installation there is no turning back. I would put everything 3/4 and I make sure I won't have problems for a long time. It is your choice, economic difference in a new bathroom ...... nothing, work, the same. Regards
It doesn't matter if you've opted for a solution, servimat1 is a capo nobody doubts it, but in this I don't share the idea. Tomorrow you can change the faucet by 1/2 point and you will see in figurines. Not to mention a small obstruction. Well ... nothing ... I wanted to clarify it because you're not the only one who has those doubts. And it is not convenient to lead to confusion.
