I need to increase the water pressure that comes to my house.How can I do this .

Typically the pressure is ok at very low rates of flow. You can test
this by trying to stop the water flow with your finger. If you can
not, the pressure is likely about 60PSI which is typical for municiple
water. At 30 PSI you likely can stop the water flow with your finger,
but it is difficult. Less than 30 PSI typically means the utility has
a problem, which you likely cannot get them to remedy. In most homes
water pressure drops drastically if you have one or more other taps
producing a large flow of water. A larger diameter pipe from the meter
to the house often produces a large improvement, but perhaps not
enough if you feel you need high flow from several taps at the same
time.
 In most locations the water contains calcium bicarbonate which
produces scale (when it loses carbon dioxide gas) in pipes and hot
water heaters. The scale is mostly calcium carbonate, which can be
removed with vinegar or most any acid. The acid also eats iron pipe,
so the pipe often fails before you get rid of enough of the scale. The
usual fix is to replace most of the pipes in the house, but this costs
several thousand dollars unless you can do most of the work yourself.
Installing a whole house water softner typically does not get rid of
the scale, but keeps more scale from forming.  Neil

If your house is tall enough, you might consider installing a header
tank as high as possible.

Thanks neilzero,
I have been trying to find a way to rate your answer but can't seem to do it

Hi, da1

The reasons you can't rate Neilzero are:

1: He has simply commented on your question; not answered it.

2: He is not able to answer it because he is not a Researcher.

You can always distinguish Researchers from Commentators because the
Researchers' names are always underlined.

However, you can always say thanks to Neilzero by way of a further
Comment, if you wish. You can also 'close' your question at anytime.

Hope this helps.
