Induction newbies with no idea of how many times this topic has been discussed here over the years, along with the source studies, might see Gary's response as an unnecessarily rude and cavalier dismissal. Don't take it that way. Follow the link to the page on the induction site. Gary knows whereof he speaks. Frankly, I'm pretty sure that anybody with health concerns can find an equal amount of interesting, well-founded information as well as alarmist and wackadoodle internet material about the health hazards of cooking with gas. There are plenty of reasons for some people to avoid gas appliances and one of them is a discomfort with the risks of the fuel. As has been noted here several times, the famous James Beard hated having gas gas appliances in his home and had a very strong personal preference for electrical ones. Apparently, with his very sensitive nose, he hated the smell and didn't like the open flames in his own kitchen. There is a distinct element of personal preference in all this, and that has to be accepted. But for the OP, the existence of internet fears and paranoia, and ignorance of how induction works, could be considered a downside to getting induction. The problem is with a potential buyer maybe having heard from "somebody" or read "somewhere" that "doctors in Europe" warn against pregnant women using induction. If it on the interenet, then it must be true, and then, OMG, induction is like cooking with an uncontained microwave radiation! And, you know, I've read on the internet from reputable sites who "really ought to know," that you can electrocute yourself by using metal spoons to stir a pot on an induction burner! (That whopper, IIRC, was from a site called Living Large.) You get the idea. Without investment of time, it gets very hard to sort out the science from the fears, the fears from paranoia, and the paranoia from utter wackadoodle. On the internet, everything is plausible, and everything is true. You can conclude, as some do, that if any scientist anywhere ever raises a question for research, then the worst case scenario has to be assumed to be true and we should ban every suspect device until we can be convinced that it is 100% safe. In some ways, this is like the fear that aluminum pans caused Alzheimer's or that low-frequency ELF from high-voltage power transmission lines caused leukemic cancers in children. The reality is that there are a ton of variables that affect cancer rates and some scientists apparently hoped that they could prove a link to living near the high-tension power lines and thereby protect health. The problem with the early research on this was that it simply associated home location to power lines as though no other variables need to be explored. As some subsequent studies showed, people living in close proximity to high-tension lines tend to be poorer that the most of the population, poorer people in industrialized societies tend to have higher cancer rates, and when you control for income levels, it seems that there were not statistically significant differences between the cancer rates for the lower income who lived near power lines and those who did not. The subject continues to be studied but the numbers of variables are so large that study results continue to be inconclusive as to measurable effects. When you need absolute reassurance and cannot find it, then you are relying on your personal risk assessment. Take the 1500 or 1600 dishwashers that catch fire in American ktichens every year. Some people see that statistic and think that is outrageously high and nobody should put a dishwasher in residences. Others look at the same statistic and think: there must be 75 million homes with dishwashers in this country and the risk of a fire is so tiny and trivial that I don't care about it. Back to the "doctors in Europe" question, many internet posters assume (incorrectly) that the newer "pregnant women" studies from "Europe" come from the European Commission Directorate-General of Health and Consumer Protection's Scientific Committee on Toxicity, Ecotoxicity and the Environment. That is not the case. As far as I could tell from the last time I tried to check out this "European doctors say . . . " report was that the concerns actually come from a non-profit organization calling itself the "International Commission on Non-Ionizing Radiation Protection" and some studies funded by them (from Slovenia, I think.) This group starts with the premise that we are all exposed to too many electromagnetic fields (EMF). Induction ranges produce EMF --- but, then, so do a ton of other devices from cell phones, iPods, and televisions to everything with electric motors, such as blenders, and on out to microwave ovens. The self-named Commission has established standards and believe that they have found some evidence that some induction cookers produce EMF levels at 30 cm (1 foot) that exceed what they say the strength should be at that distance for what they regard as safe for an in utero fetus. Can you find some doctors in Europe who would adopt this? Sure. Probably here as well. Is it generally accepted medical practice in Europe or here? Nope. WIll the mere existence of questions scare some people who come in to look at the OP's house when she and her husband eventually put it up for sale? Yup. Some people will be put off and want a different stove. But the thing is, some people will be put off by presence of gas appliances, as well. There's what somebody here once called the the "kaboom" factor. As a practical matter, the actual risk of a gas appliance exploding and causing a house fire is small. Something like maybe 12% of kitchen fires caused by gas stoves were due to gas leaks, IIRC from the last time I checked the National Fire Protection Association statistics. Overall, the biggest reason for home-fires caused by appliances (45% of the fires) was unattended cooking and burners accidentally left on after cooking. Overall, gas cooking appliances were not as likely to cause a fire as the electric ones simply because gas stove owners were only half as likely as electric stove owners to leave an unattended pot cooking on a stove or leave a burner on after cooking. But, in this regard, you might note that induction would be even safer than both gas or radiant electric because: (a) induction burners don't have the waste heat output that can ignite sleeves, towels, etc. that a gas or radiant electric burner can ignit; (b) if you slop or spill oil when frying, there isn't a very hot burner or flame to ignite the spilled oil; (c) most induction cooktops and ranges have safety shut-offs -- that is, if an empty pan overheats, sensors (on many induction ranges and cooktops) will shut off the burner and keep the pan from burning your house down; and (d), if you forget to turn off a burner after you finish with a pot, nothing can happen once the pot is removed from an induction burner. For every potential health problem you can cite for induction, there seem to be more for gas ranges. There are ongoing studies on the potential adverse health effects of combustion by-products from using gas ranges and cooktops in residential and commercial kitchens. Search the internet and you can find postings with titles like "Gas cooking emissions can stifle infant development ..." A year ago, there was a US DOE and EPA study on the need for vent hoods when using gas ranges and cooktops which got some discussion here. IIRC. there are a couple of NY Times articles that sparked that discussion and you can find them here: http://www.nytimes.com/2010/04/01/garden/01fix.html?_r=0 http://well.blogs.nytimes.com/2013/07/22/the-kitchen-as-a-pollution-hazard/ The link to the gardenweb discussion is here: http://ths.gardenweb.com/forums/load/appl/msg0715091316878.html So, can you make the family gas proponents read that stuff? Maybe they will all decide that you all need to eat raw food and just stay away from all cooking devices. ;>) This post was edited by JWVideo on Wed, Aug 20, 14 at 14:51

I assume you mean filled up rather than the 2 or 3 inches your canner specified. NO it will make no difference in the tuna. The high pressure (and higher temp.) would have been throughout the canner. If you overfill canner, water instead of steam may blow out valve if you have that type. Jim

BUT, without the low flow shower head the flow at the shower is 5 gpm and with the low flow head it is 2-1/2 gpm. House was built in 1953 and we do not use other water sources when shower is running because of pressure/volume drop. Will get around to doing a copper re piping job someday. The guy you like says 24K and your sparing partner, ;) , says 32K. They are both a unknown to me at the other end of the internet from where I am.

Finally able to post an update... unfortunately our phone lines (which include internet) went down for three days only to be followed with the entire house coming down with the flu this week. Andy-- Yes, we have a guage at the pump. We have a 30/50 and the pressure switch seems to be in proper working order. I am told 3/4" plumbing. Justalurker-- the problem was not from day one, it was a gradual occurrence. Everything checked out as far as the way it was plumbed and with the bypass valve knobs. However, when we moved on to removing the element on the sediment filter, our pressure returned to normal. So our plan for tomorrow is to locate and install a 4.5" x 20" big blue with pressure gauges installed before and after... I realized after tonights troubleshooting (and further research on the web) that the existing filter is closer in size to the little blue filter when it should have been the big blue size that you suggested to me in a previous post. Also, after searching "filters" in other posts, I came across this information you posted regarding filter changes: "Filter elements should be changed when the pressure drop across the filter approaches 15 psi not by a calendar. you change the oil in your car according to mileage not months." So I will follow this recommendation unless you suggest otherwise. Thank you for the information on the filters bus driver. It would be great to only have to change our filter every 11 months. I am not sure how much of a need we have for the filter but based on the looks of the element after a month of use, it seems like a good idea. Also, I was told it was a must in our (Florida) location. Thanks again to all... your help and patients is greatly appreciated.
