When Does the Filter in your Above Ground Pool Need to be Cleaned?

December 24th, 2010

If you have an above ground pool in your backyard, you have a choice of two different kinds of filter to keep the water clean as it goes through the pump. Some systems use a sand filter; others use a filter made of diatomaceous earth. Now with both kinds of filter, backwashing is a proper DIY option. Depending on the kind of filter you use, you’ll have to perform different steps to get the job done.

Let’s start with the diatomaceous earth filter though. To start with, turn the filter off, and find the switch on the filter somewhere that lets you change the filter to backwash mode. You should be ready to switch the pump back on now once that’s done. When water starts running out of the pump now, depending on how long it’s been since your last time cleaning the filter, the water should be somewhat dirty. When you leave it running for long enough, the water coming out of the pump begins to clear up. That indicates to you that your pump is now clean and ready for service again.

All you need to do then is to turn your pump off, and set the dial back to the way it was. You’ll need to check the pressure gauge to see that everything looks okay. And then you should be ready to fill the filter back up with the diatomaceous earth. The amount you need of course will depend on how large a filter you have. You’ll need to check with the owner’s manual to your filter, before you scoop diatomaceous earth into it. Make sure that it fills in evenly, and close everything back up. You’re done now with a job well done.

If your above ground pool has a sand filter, backwashing it follows somewhat the same kinds of steps. The pressure gauge on the sand filter usually shows you when the filter needs to be cleaned. If the pressure gauge shows higher pressure than normal, or if the water flow indicator is up to a third lower than normal, these are your signs that your filter is ready for a good cleaning. All you need to do is to turn off the pump, reverse the valve setting for a thorough backwash, open a different valve in some models for water to flow in the other direction, and turn it on. Once everything is rinsed clean, you shut it down, turn off all the valves and you are done with it.

How great a Gift does an 18 volt Cordless Drill Make?

December 24th, 2010

Do you have someone on your gift list who is handy around the house and loves the sense of power it is, whipping out a great cordless drill at the slightest provocation ? Consider these two winning 18 volt cordless drill units – the Black & Decker CDC180ASB and the DeWalt DCK435C. The Black & Decker is a simple drill unit that goes for about $65 on Amazon, while the DeWalt is a kit of four 18 V devices, one of them a rechargeable work light, that goes for $350 at the same outlet. Depending on your budget and the tastes of the recipient, these will make kickass gifts to give a handy type on your list. Let’s go a little deeper into these devices and see how good they are.

The Black & Decker is a great little drill with a two-year warranty, and plenty of power in a motor that provides 120 pounds per inch of torque. It comes equipped with a precise variable-speed switch. Squeeze it all the way, and it spins at a full speed of 650 RPM (or in reverse if you want to unscrew stuff). Squeeze the trigger only part of the way, and it spins slower. The lightweight drill makes it easy to work for long hours, and there are quite a few convenience-related features on this 18 V cordless drill. The drill for instance comes with a keyless chuck that makes it a snap to change drill bits (you get a set of 20 drill bits to go with it and a carry bag). The handgrip is soft rubber, and you get a six-position clutch to help you work free of worry that you might strip screws at any time.

The DeWalt is a package of four tools (the package weighs more than 20 pounds) that comes in a great tool bag that should see anyone through a good lot of DIY. The biggest tool in the bag is an 18 volt cordless reciprocating saw with a keyless blade clamp. It simply dares one to find lumber that could overwhelm it (Hint: it should be pretty hard). The 18 volt cordless impact driver puts out more than 1000 pounds of torque as it spins at a mind blowing 2400 RPM. It’s just the tool  to unscrew the rusty screws and nuts. The super powerful half-inch 18 volt cordless drill (hammer type) that puts out 400 W of power will help one fly through projects with ease. And finally, there is that flexible-head rechargeable lamp to help spot a light on a work area.

All these tools are powered by nickel cadmium rechargeable batteries. They come with a single tool charging station. If you want to charge more stuff at the same time, you could buy accessories to help you do that. These are tools that you just couldn’t go wrong with. And that’s not just talk.

20th Century Italian Coffee Makers

October 8th, 2010

Do you like the style of the original Italian coffee makers? The first modern espresso machines actually gave birth to the cafe. In Italy, the first modern espresso machines were very expensive and rather large. The cafes purchased a machine and manufactured espressos to its patrons to make up for the cost of the machine. At this time in Italian history, only men were able to visit the cafes. The women never experienced the great taste of these cafe espressos.

Women and those who could not afford the cafe espressos were stuck with making coffees and espressos at home. They did this with a stovetop espresso maker. The coffees and espressos made with this contraption were a lot weaker than cafe espressos, but they made do.

In the early 20th century, it was a pain to have to go to the cafe to get an espresso. So, Bialetti started inventing a better stove top espresso maker that was made out of lighter metals such as aluminum. He finally came up with a design that was light and achieved great coffee bean extraction. He felt that the end result was very close to the espressos that people were able to get at the cafes. He called his product the Moka Express. This became a very popular product and almost every Italian home owned one of these stove top espresso makers.

It’s interesting that Gaggia basically started the cafe and espresso growth in our world. Also, Bialetti helped us put espresso makers into our homes. You can still find the original Italian espresso makers in use across the world. If you are looking to buy and original, then you should expect to pay a lot for these collector items. However, if you are looking for a solution to making your own espressos, there are a lot of at home options these days. For a couple hundred dollars you can buy a pump driven espresso machine that will rival any espresso made by a cafe. Take a look at Nespresso essenza espresso maker or gaggia espresso machine.
