Hi all!

I am planning a new bathroom remodel.

Water supply is in the basement. From the street I believe there is a 5/8 ou 3/4" pipe, then it goes to a 1" pipe and from there down to 3/4" and down to 1/2" to the hot water tank.

I want to replace the 1/2" pipe to a 3/4" to supply everything.

I understand that this will not give me more pressure but will give me more flow.

The new bathroom is on the 2nd floor. From the hot water supply to the shower, there is going to be about 40' to 50' of 3/4" piping and of course I'll reduce to meet the faucets.

In the shower, I want to install a rain type showerhead, a massage shower and feet faucet.

My worry is that I am not sure is I'll have enough pressure for all this AND the time it'll take for the hot water to reach final destination... without wasting water...

Any advice?

Thanks in advance! ;)

Increasing the diameter of the piping will increase volume (not pressure) Also when installing a hot water line more then 50 ft from the source it is a great idea to install return circulation.

Also I would check the pressure incoming before you go through the expense of increasing the lines then finding the shower only trickles.

Check with the shower head manufacturer what is the minimum pressure they recommend.

I bought an $850 shower head and even after removing the flow restrictor I do not get the full benefit of of the various flow patterns available from it as I have 48 PSI

on the door is from the police for removing the flow restrictor.

And while they are they they will have a search warrant to check for all of the matress tags.

Hi Sylvan,

Been to the link you put in ur message... I answered Y to all ur questions... the only thing is that nossiter is in australia... and i live in quebec...

we are somehow taxed for the water we use... a flat rate of about $50.00/y. Mind you... heating water is expensive and i'm always looking for new creative ways to save on costs... is there any other manufacturers on circulating pumps in canada?

as for you lack of pressure... isn't there a way to put a pump to add pressure to the line?

many thanks! ;)
