My water is somewhat hard and heavy with chlorine. My plumber is going
to install a filter on the main water line into the house. I am
concerned with a reduction in water pressure like what happens when I
put a filter on the shower head. He says this whole house water will
not reduce the pressure. Any thoughts?


What kind of filter will take out chlorine and hardness?

Any filter has some degree of resistance. But on a scale of 1 to 100
maybe your water pressure is 100 and the filter has a resistance of 1
- is that gonna bother you? What if it was 5? 10? How much of a
(relative) reduction did you find in the shower head? If the plumber
knows what he is doing and puts in a filter of the proper capacity,
there should be no significant or unacceptable or maybe even
notcieable reduction - and for that slight reduction you get a
benefit. It should not be "like your shower" which apparently is a
big, unacceptable, very noticeable reduction.

We have a whole house filter (but not for hardness or chlorine) and
when we notice a reduction in "pressure", is when we know it is time
to change the element. (Actually, what we notice is a reduction in
VOLUME from the change in pressure.)

Those are my thoughts on the matter - what are yours?
