Hey guys.
I have 1.5" coming out of the pump feeding 20 hotel rooms. However immediately out of the pump the piping reduces and the WHOLE building is feed off 3/4" copper. So I have an idea and I want to run it past you experts.
I want to divide the building in 2 parts.
One part will be 12 rooms (side A) and 1 part will be 8 rooms (side B). Now side A is going to get repiped. All the water runs out the back of the mechanicle room underground and along the back of the building. This is actually 1" galvanized piping. All this will be ripped out and replaced with 1 1/2" piping with what we are hoping is 3/4" take offs to each room (we haven't dug it up yet).
So this will solve the water issues for that half of the building. However Side B is not as easy to get at and the owner doesn't really want to rip open walls to replace piping as this would be VERY expensive. But what I want to do to eleviate the problems is run the 3/4" lines feeding side B (which is actually 2 seperate buildings each with 3/4" supplies) off of a 1 1/2" manifold. This goes for both hot & cold feed lines.
Now am I better off going with a true division and with 2 bladder tanks (he currently has 1 80 gal tank)? One for each side of the building. Or would I be better off just going with 1 big bladder tank and running the whole system off that one tank?
Because I have sized out the supply requirements and even @ 1 1/2" piping feeding Side A of the building we're stretching the capacity.
So I guess my REAL question is will installing 2 bladder tanks give me more capacity to help keep up with demand during peak times? And is this any harder on the pump?
