In response to Re: low flow frost free sill cock
: ever since I had a frost free sill cock replaced 2 years ago, there has been noticeably reduced water pressure and volume. Last year I had the inside piping to the valve increased to 3/4 "copper and it did not help. Any ideas??

Pressure cannot be increased by increasing pipe size Volume changes not pressure.

You maybe able to disassemble this sill cock and check the washer it could be a beveled and not a flat type which causes even more restrictions

Also Globe type of valves do offer a lot more restriction then gate or full port ball.

You can possibly locate a better brand of sill cock like J R Smith or other decent quality brands
