I needed to solder a new copper line to an existing cold water line in the master bath.
I used an air compressor to blow out the lines and kept the pressure less than 50 pounds.
Examination of the inside of the original 1/2 line looked pretty clean
After soldering the line and turning the water back on,
I noticed the water pressure was low in the guest bath (master bath still under construction).
For example, the Washer pressure seemed OK.
However, the bathroom toilet, sink and tub were quite low.
The washer is located in the guest bathroom as is the toilet, sink and tub that had low pressure.
I did find mineral deposits (white hard) after:
1) Removing the flowmaster from the toilet.
2) Taking apart the bathroom sink faucet and stop cock.
3) The bathtub cold initially had virtually no flow.
I then took apart the the bathtub value (old PP faucet) and blew the cold line from the PP value with the
cold water line from the washer disconnected. Got a small handfull (estimate < 1/8 cup) of mineral deposits.
Everything appears to be clean now (no mineral deposits in sink screen or in Fludimaster) and tub flow has improved
but still not what it used to be.
Have checked the water meter with everything turned off and needle does NOT move so assuming no leaks (I HOPE).
Any suggestions how to proceed?
