Jan:–Remove the aerator from the kitchen sink faucet spout and remove any pipe dope or debris that may have collected there as aresult of your recent plumbing activities. As for the lack of great quantities of hot water gushing from your taps….I suspect that the lower thermostat is set far to low for anyone that enjoys hot water in the bath. After reading the warning from Big Brother about the penalties that apply to all those that dare violate the law of the land when they set the thermostat higher than 120 DEGREES, and after you have decided to risk the wrath of the HOT WATER POLICE…turn that rascal up to a point that will deliver copious amounts of hot water yet wont scald any members of your household. Lots of luck Bud. This message will self destruct in five seconds… ………..fffzzzzzztt..pooof
