Faq – About Aerator Faucet
Ken asks…
what does a low flow faucet aerator do besides reduce water usage?
Staff answers:
If you have low water pressure it increases it a little bit
Mandy asks…
What is the purpose of the aerator on a water faucet?
I enjoy the flow a lot better without it on there!
Staff answers:
If you like it without the aerator, no need for it at all. Some faucets spray funny without the aerator. Also, the aerator will trap any scale from the pipes and just has to be cleaned out periodically. So leave it off!
Except in the kitchen where you wouldn’t want any debris to end up in your drinking water, etc.
Lisa asks…
how can you tell if you faucet has an aerator installed on it?
I just bought a new house, and I’m thinking about getting some. How do I know if these are already installed in my faucets?
Staff answers:
Faucet aerator styles.

If there is no aerator, you can stick your finger up the pipe.

Faq – About Frontier Airlines
Chris asks…
Frontier Airlines?
I am looking to fly from Denver to Minneapolis in about a month. I see Frontier advertising really cheap rates all the time, but of course, now that I am looking I can’t find any! So does anybody know if Frontier will be having a sale anytime soon? Are there any patterns to when they have sales, or is it random?
I just don’t want to pay full price today and then next week the fare goes down.
Thanks for your help!
Staff answers:
Check out www.farecast.com
it can help predict (usually 70% accurate) as to when is the best time to buy your tickets.
Also, if you do not mind flying a different airline, i’d check out www.kayak.com
it will list many different airlines and their prices.
Best of luck to you.
Charles asks…
Is Frontier Airlines a safe and a good company to fly?
I’m planning to fly in the states, and I want to to if anyone knows if Frontier Airlines is a good company, is the cheaper one flight ticket I found but I want to know if its worth it to buy it or if you can recommend one good company just do it please!
Staff answers:
Frontier is a good airline. Though they filed bankruptcy, it has nothing to do with them being financially distressed. It was because they wanted to freeze the assets so this credit card company they partnered up with could not access the airline’s money. The credit card company was charging Frontier a lot of money for fees so the airline declared bankruptcy.
I hear that people like to fly Frontier. They have a pretty young fleet of Airbus aircraft and have a good safety record.
Sharon asks…
The noise under the Plane frontier airlines?
Yesturday we went from Denver to Chicago on Frontier Airlines and we heard on the ground these noises that sounded like a saw going back and forth only when we were on the ground or Taxiing.
What is that?
Please give a Detailed Explanation.
Thanks
It was in the middle of the plane.

Here is another supplment to Sul’s info
http://www.airliners.net/aviation-forums/tech_ops/read.main/93654/
skimming through the posts i copy&pasted three important ones
this one is from Michael
It is the HYD PTU (Hydraulic Power Transfer Unit). It comes on automatically when the differential pressure between the green and the yellow system is greater than 500 PSI (normal system pressure is 3000 PSI). This normally happens, when you start or shut down an engine. The PTU is working only for a few seconds or even less than that, because it stops when the pressure in the associated system is at 3000PSI again (that’s the “barking” sound). And there are not to many hydraulic functions needed while shutting down an engine. So the pressure is maintained easily.
There are a few more parameters that affect PTU automatic operation. But that would lead us to far off topic.
The PTU is indeed the correct answer.
I will shed a bit more light on why the pitch changes as the engine spools down.
As Michi stated above, the PTU comes on when the pressure in the other system drops. The PTU runs just long enough to repressurize the system … A second or two, then stops. During the next few seconds, the system depressurizes slowly due to “internal leakage” in the hydraulic system. When the difference in pressure agan reaches 500 psi, the PTU cycles.
And another by Pete
As the engine spools down, the flow from the engine driven pump available to drive the PTU is reduced, therefore the PTU speed and power transfer to the second system is also reduced. Thus, it runs slower, and takes a bit longer to repressurize the second system – this explains the lower pitch. When the engine stops, the PTU no longer receives flow from the engine pump, so it, too, “dies”.
I would be glad to answer any questions on the PTU or other hydraulic components. I worked on the Vickers PTU which is used on some of the A320 series.
Another signed tom
quite common. Our A319/320′s usually taxi-out on engine 2. During taxi-out, they start, turn & ignite the engine 1. Here @ AWA, our pilots
usually turn engine 2, during pushback & engine 1 during taxi-out.
As posted above, the PTU is hydraulically controlled & required to enable engine starts. Next time you are boarding any A319/320, you will also hear the outward-opening, hydraulically controlled cargo doors closing or opening after arrival @ the gate.
The A319/A320 with the IAE V2500 series engines have a very dramatic & distinct sound when starting! Once the engine igniters have been turned off, the engines have a very high-pitched whine, but yet quiet. The idle also audibly increases.
In the US: AWA, jetBlue & United use the IAE V2500 series engines. All the other carriers use the CFM-56-5 series engines.
However, the composite airframe produces that unique high to low pitched “Dolby” effect, during approach. I figured that out here in PHX, by observing all the various A318/319/320 & 321′s for carriers on ILS Arrival for Runway 8. My apartment is 5 miles north of PHX & 2 miles south of the final approach pattern. So, the planes are usually @ 6000ft.
Same thing in PIT, my folk’s house is on ILS Arrival for Runway 32. They are about 10 miles out. All the US A319/320/321′s & UA 319/320′s have the same high to low pitch as they pass overhead. I like to show off for my parents! When we are sitting on the deck outside & I announce “airbus”, without even looking up.

Faq – About Aeration Septic System
John asks…
Is this offer insulting? OR should it be a red flag to the seller?
Our house was listed at 225K. We dropped the price to 209K to improve traffic, we live in a rural area that is not optimal for moving real estate quickly. Anyway in the meantime we did $17K worth of improvements to the home, which is 12 years old. We contracted a new aeration septic system, RV dump, all new stainless steel appliances, and a new heat pump and 80 gallon water heater.Yesterday our realtor calls us and shows the house for the second time. the couple loved the house and made an offer, for 60K off our asking price, 80K off the original price AND is asking me to leave furniture items! (Chairs, handmade bookcases, zero radius mower, etc). I dont want to run off the first offer we get, would like to negotiate with this couple, but I cant help feeling that we are trying to be taken advantage of…. Advice? We are to counter offer by Saturday afternoon.
The sad thing is this: We don’t HAVE to sell this house. We want too in order to be closer to schools, work, etc. We didn’t bite off more financially than we could take in the beginning and we are not in over our heads or about to lose our home or anything like that, so its kind of hurtful to have someone come in and try to find out how “despearate” you are… which we arent. its money, not anything else, i just need to keep my feelings out of it and just work with the numbers i suppose….. geesh! what a world we live in today!
Staff answers:
You shouldn’t look at as a personal insult. It’s business for both of you, and there’s a lot of money at stake.
When someone starts *that* far off your asking price, they want to see how willing your are to deal. Sometimes, people accept lowball offers. It just depends on their personal situation.
If I were you, I wouldn’t counter that offer. If they’re interested, they’ll make a new offer of their own.
Paul asks…
I did have a full home inspection, no septic was mentioned!?
We had a home inspection and it stated in there it was public sewer because that is what was on the listing sheet. We were told today at the realtors office that when the seller purchased the home they had aeration listed on their sheet. Why didn’t they list it again? I think they knew it was a bad system. I have documentation of everything and we were absolutely lied to. Who do we go after. The sanitation co. told us today, that we have the most expensive sytem made and it is $500 every two years to maintance. I had stated $3,000 at minimum and that is just what he could see. We didn’t even get our $500 back today for that out of pocket expense. Yes, there should have been a septic inspection, had it been known. The home inspector we used does not cover septic systems. This whole thing is a mess and I don’t know where to start. Thanks for all your responses before!
Staff answers:
Call a lawyer and seek the home inspector, he and the realestate people totally should have known this. They are at fault. Buyer beware!

Faq – About Water Aerator
John asks…
My tap water has grit and small stones and they clog my aerator quite frequently. What does this mean?
Are our water pipes corroded?
Staff answers:
Hi put a in-line filter with a stop tap on either side of the filter so u can Clean the filter
Donna asks…
How will the fish sleep when the water in my aquarium is turbulent? does it mean they havent slept for yet?
They are in my aquarium for 6 months. Three of them already died from a total of 24 all angelfishes . The turbulence is caused by my water filter/aerator which is set to high pressure.
Staff answers:
Fish don’t sleep. They don’t have eyelids.
Maria asks…
what is wrong if water is coming out of the aerator when the dishwasher is running?
Staff answers:
It means that your sewer line is partially plugged up, when your dishwasher goes on the “discharge cycle”, it gets rid off the water very fast and that is causing the water to come out the aerator,
Also I will never recommend people to use the “Garbage Disposal” in the kitchen because that’s the best way to plug up your sewer line

Daniel asks…
What would cause low pressure in a faucet besides a clogged aerator?
I took off the aerator to clean it, and the water still had low pressure (though I suppose I don’t know exactly what the flow should be like once the aerator is off; but it seemed weak to me). I cleaned the aerator and put it back on but there was no improvement.
Staff answers:
There could be debris stuck in the stem
there could be insufficient water coming in at the valve under the sink
if it’s only at that faucet, i recommend removing the supply line from the valve feeding the faucet under the sink, open the valve and see how much water comes from there as a starting point.
Laura asks…
where do we access the aerator screen to clean it out on a kenmore quietguard dishwasher?
diptube failed in our hot water heater and all lines are blocked with junk. where do i access the dishwasher to clean out the aerator at the incoming water?
the plastic dip tube was crumbling and the pieces have all come thru our hot water. now all of our faucets and appliances are blocked with the tiny bits of plastic.
Staff answers:
There is no removeable cleanable aerator screen on the incoming water supply for a dishwasher, like there is on a washing machine. If gunk gets in the fill valve, as DVD says, you should replace it or have it replaced. I’m more curious about the diptube problem in the water heater, trying to figure out why that would make the sediment come out and get into your dishwasher, it really shouldn’t have anything to do with it.
