This is smiliar to the question I asked previously, and I need a bit more help/clarification.
I need to replace the cartridge in the kitchen faucet (with sprayer wand), and cannot shut off the hot water using the shut off value (I'll call this value #1) underneath in the cabinet. I suspect the valve kicked the bucket after ~6.5 years.
There is a shutoff value (#2) in the basement leading up to the kitchen sink area for hot water, but that valve doesn't work either. So, it looks like my only choice is to turn off the water going _into_ the water heater (there is a different style shut off value, #3, just before the water heater, and I'm hoping that still works) and use up the hot water by draining it thru a faucet somewhere. Then, replace shut off values #1 & #2 and the faucet cartridge.)
Do I have this right? I'll basically be draining the water heater completely to do this work, and turn it back on and fill the water heater again, wait for it to be heated, before I get any new hot water.
Also, both values #1 and #2 have screws in the middle. Is this the type that nees sealing tape?
Sorry if my questions are too basic. I'll have to this work late at night, and won't have time to run back and forth to the hardware store (and make sure I have hot water for the morning).
Thanks.
