Thanks Jon A.. we just recieved this and thought it was worthy of passing it on..

For those pointing out that drilling out a showerhead actually increases flow rate, and not water pressure, you are correct, but I think this is a common disconnect between the lay-person's vocabulary and the professional's terminology.

 

If you have an issue where someone flushes the toilet, or turns on the shower/sprinkler/etc and you can hardly get any water out of a second faucet, many people would say "this water pressure sucks" but what they actually mean is, this house has terrible flow rate.

My 1840's cottage, for example has water pressure of about 101 psi (which is pretty high), but has old corroded pipes under the house that have severely restricted the flow rate of this properly pressurized water. As a result, I can get enough water from any one water-using device, but trying to run multiples is very difficult.

If you're on city water (wells are a different story) it is much, much more common to have flow problems (not the city's responsibility) than pressure problems (at least partially the cities responsibility). So frustrate yourself and call the city utilities dept and ask what they can do to help fix it just to be told they can't. That is why I am so thrilled when I ran across your website (www.highpressureshowers.com) and you were able to fix my problem.
