I had someone ask me if it's possible to increase the flow from the shower head. This is what I told him and thought I'd check here to see how much I got right (along with some questions):
- Shower heads (including hand held showers) are low flow in California. It might be possible to get one (new, hand held) that isn't low flow in another state, but I wasn't sure.
- The early forms of low flow were made by inserting a plastic washer in the shower head. These could be removed to increase the flow. Now, however, the modifications are within the unit, or harder to get out and it's difficult to modify the head to increase the flow.
- His flow looks what I'd consider "normal". He is thinking that increasing the diameter of his pipes (in the walls) would help increase the flow. Since he's in a condo unit, with other units in the same stack, increasing his pipes wouldn't achieve anything, since the stacks' delivery piping would still be a smaller diameter, and this is what would limit the flow.
- The diameter of the hose on the hand held portion of the shower is obviously smaller than the 1/2" pipe that feeds it. However, this diameter is fine for the amount of flow that comes out of the shower head. That is, putting a larger hose between the source and the head woudn't increase the amount of flow, since the shower head has a set flow rate.
- Increasing the pressure would increase the flow, but there is no way to increase the pressure in his shower, considering that he is in a condo with a common supply.
Thanks,
