Simple plumbing questions
So we are planning the plumbing out and I have a little question...
The guy helping us with the plumbing wants a 3/4 “ line coming from the city inlet valve into the water heater. We got a small residential 110 tank heater and the inlet to that is 3/4”..., but I can’t seem to find the right thing to buy online? Maybe I’m looking in the wrong places or I’m not understanding the numbers on the products being sold? But it looks like to me that most of these city water inlet valves are 3/4” coming in (a normal watt hose connection) and 1/2” fitting on the inside of the bus. Is there such a thing as a 3/4” and 3/4” city water inlet valve? Is there a reason why it should be 1/2 on the inside? Like maybe it helps with water pressure?
My guys plan is to run 3/4 to the water heater and then 1/2 to the rest of the bus. And solely for the reason that the water heater has 3/4 connections. I’m thinking we’re just going to have to put adaptors on those 3/4th... and just use all 1/2 thru out the bus. Any advice is appreciated. ;)
