I am on a private well with ¾” water lines from the well to my storage tank and hot water heater in the garage. The lines from this equipment to the kitchen, and baths are ½”. I remodeled my upstairs bathroom and hired a plumber to move, and upgrade the ½” water lines to ¾” for the new bathroom.

In the new bathroom, we installed a single sink, Jacuzzi tub, and shower with two outlets, a hand held body wash, and showerhead. When we open the tub valve and the both shower valves, we get water from all but the hand held shower outlet.

I went under the house to check the shut off valves where the plumber tied into the existing system to make sure they were completely in the open position. I found that the plumber tied the new bathroom ¾” hot water line to the existing ¾” line from the hot water heater but tied the new ¾” cold water line to an existing ½” line.


Is this a correct installation or the cause of the problem I mentioned, (no water from the hand held body wash)?

I should note that before we had this work done, we lost some water pressure when we opened two or more outlets at the same time. This was not a dramatic loss of pressure but enough to notice.

Sorry for the long winded description but here is some additional information that may help in answering my question.

· Our plumber told us the new fixtures we had him install were ½” valves. (We did not know this until after we bought them. Our plumber also told us we would not see a reduction in water pressure, just that they would be slower to fill the tub).

· The well is about 200 feet away from the equipment in the garage.

· There is a slight upwards grade from the well to the house.

· There is a Collagen Gold Water Softener install in the system.

· There is a Big Blue 20” water filter installed in the system with a 10-micron filter.

Any ideas what the problem is?
Thanks Kirkwa

The norm is 3/4" supply main, with 1/2" on the branch line of the tee. If your that worried about the pressure loss, due to the long run, here is a site you can go to upgrade your pump.
