Check to make sure the water meter is open all the way. If it is a meter? Have you had any plumbers out recently? They may have not opened the meter all the way.
Check your backflow device to make sure the handles are open all the way.
Walk around your property looking for a mainline leak while the system is on.
That is enough for now.
Good Luck
Thanks. Good suggestions. I had the main turned off a couple months ago when I replaced a shower valve. I'll double check to make sure I turned it back on all the way, but I think I did and I'm not having any problems in the rest of the house.
When I looked at the backflow area, there were two handles and both were on all the way.
There are no obvious leaks in the system. I think I would notice with the horrible draught we're having in Texas right now. I do have a layout diagram from the installer that the previous owner left, so I have a general idea where the pipes run. I will do another walk around this weekend.
Any thing else I should look for or check out?
