Hot or cold water from pot filler?
ChefTalk.com Top Picks
(I have to deal with contractors for my apartment building, and I would never, ever let them just walk away from a mistake like that. They messed it up, they should fix it as fast as possible -- ALL of the necessary work.)
From the Minnesota Department of Health Website:
Use cold tap water and heat it on the stove if you need hot water for food preparation. Hot tap water absorbs more lead from pipes and pipe solder. Let tap water run for at least two minutes if the water has been standing in the pipes for 6 hours or more. This flushes out the water that might have absorbed lead from the pipes or the solder that joins the pipes together.
Here is the link:
The cold water is nice to have because you can knock down a boiling over pot real quick. You could do it with hot too I guess since it's not boiling. But it's quicker with cold.
But the thing about the stock... yeah, you never wanna start your stock with hot water.
But nevermind all of that. Just tell the contractor to fix it. Plain and simple.
If the contractor did not do what you requested then you should make his do what he promised to do. It sounds to me like he is just trying to get out of doing work.
Personally I would prefer the hot water. It is true that you do not always want to start with hot (potatoes and stock are two good ones as others have already mentioned), but for me I find that more often then not, I start with hot.
You really need cold, right? what about boiled eggs and thing like that.
I'm editing myself because it's not really funny for you. I'm really sure if you look hard enough there is some way to get cold water to that installed pipe without ripping out tile. If you have to do major thigs then ,oh well. He or she will just have3 to do it
You ask for oranges and get apples, I'd be complaining!
Thanks in Advance
I'm thinking that the reasons for the taste differences are 1) leached substances due to temperature 2) leached substances due to longer time sitting in the pipes and 3) much lower dissolved oxygen in the hot water. I don't have a reference for my suggestions, but I definitely notice a difference in taste.
I wouldn't take the chance. And as others have pointed out, cold water heated up will be better tasting.
Anyway, how far from your pot filler is the hot water heater? It certainly isn't going to be hot water coming out that filler immediately anyway. Just like it takes awhile for the hot water to show up on my tub or sink hot water faucet.
Why Not Hot Water?We all know it is much quicker and more convenient in your busy schedule to throw some water in a pot and boil it for your instant coffee, instant cereal, top-ramen, spaghetti, etc. But there are reasons you should never use water from the hot side of the kitchen faucet, even though it saves you about 5-7 minutes.
Here comes the science:
The insides of a hot water heater contain metals that can, and do corrode. Some of the pipes in your home that are not made of PVC may have lead soldering. Hot water will dissolve metals, especially lead, much quicker than cold water will. Not to mention that over the years of daily use of drawing gallons throughout the day in cycles causes the water from the local utility, with all of it's impurities to collect and precipitate in the bottom of the hot water heater. This is a prime breeding ground for bacteria. Perhaps they cannot survive in an environment where the water is around 140°, but as soon as the water cools down enough due to a power outage or extended leave (if you turn off your water heater), all the necessary nutrients are there in an 80 gallon soup.
I personally saw a demonstration by a company that was in the business of manufacturing and selling water distillers for the consumer market. They had 2 five gallon glass jugs filled with water. One of the jugs was filled with with the water that been taken from an 80 gallon water heater that had been in use for a few years, and boiled down from 80 to 5 gallons. The other was filled with distilled water. While the distilled water was crystal clear, the other had a 3 inch layer of precipitate containing heavy metals, impurities, and bacteria. Truly a revolting sight. Also, ask any gas or electric utility worker or plumber who does work and repairs on water heaters and they will confirm this and probably offer a few horror stories of their own.
If you plan to cook with tap water, run the cold water for a minute or so and use that cold water for your cooking. You may want to save the 'non-potable' water that you flushed from the pipes as you can use it for cleaning and such. And by all means, NEVER draw warm water for infant formula. Since infants are developing at a rapid rate, they are much more vulnerable to the concentrations of impurities and lead and could potentially get lead poisoning from warm tap water.

The hot water line can have added contaminants that come from the hot water tank and its anode. It's better to use the cold water line as a fill line.
After reading the many replies, I can only hope that you get this problem corrected soon. I wouldn't rule out calling the contractor as soon as possible so he can come out and correct his mistake...don't let too much time pass before you do this. I'm sure you have been waiting to fill your pots with this fill line (until you fix the line)...so just keep filling the pots with cold water from a different station until you can get the problem resolved in a timely manner.
We hope to hear from you in the next couple of days to hear how things progressed...have a great day!

My neighbor made a suggestion to me about adding a pot filler in my kitchen near my stove and as I am positively considering this I had thought that for btu efficiency, tapping into the hot supply would be better than the cold line. Since I am about to rip up the sub floor in the kitchen, this would be a perfect time to do this. As I briefly looked up a few styles I noticed that many of them are for cold water use and I thought that was unfortunate. I am so glad I did some further research and found this forum and particularly this comment by Ashley, about not using the hot water for all the above reasons I feel that my education has gotten off to a good start and will tap into the cold water and probably add a filter system as well. The research is on going but your discussion about the impurities, especially heavy metals in the water tank would be a huge negative. I am going from an electric stove to a duel fuel so I don't mind using more gas to heat up a pot of cold water rather than save a few minutes and use the hot water and everything you said makes total sense. I am sure there are other issues related to cooking that are spelled out by others in this topic that relates to the art of cooking I am very glad I found this forum and read many of your comments as it saved me from making a mistake. I am not a chef but like to cook and want a nice kitchen when I am done remodeling and the idea of a pot filler my neighbor suggested was a good one and your chemical reasons as to why not to use the hot line I can totally understand. Thank you so much Ashley.
