Selecting the Proper Pump for your Backyard Water Garden Feature

Written by Gerry Fung

Whether you have a preformed or a liner pond, a pond pump is a paramount component of any water feature. Stagnant bodies of water attract mosquito infestations, which are a nuisance, and also undesirable, due torepparttar recent outbreaks ofrepparttar 113293 West Nile virus. Therefore, it is paramount that you utilize a pond pump that circulates your body of water.

Pumps are available in both submersible and external (out-of-pond) models. Forrepparttar 113294 smaller pond (up to 1000 gallons of water), a submersible pump isrepparttar 113295 more economical and practical option. Submersible pumps can be placed directly inrepparttar 113296 pond and require relatively little installation. They are free of distracting noise, and for smaller ponds, can easily be utilized to drain your pond (if you hook up a hose torepparttar 113297 output flow).

Inrepparttar 113298 old days,repparttar 113299 main disadvantage of submersible pumps was thatrepparttar 113300 pump seal could rupture and release oil coolant intorepparttar 113301 water. However, this is notrepparttar 113302 case nowadays, because newer pumps are magnetic-driven, and no longer require coolant. “Mag-driven” pumps are slightly more expensive, but they haverepparttar 113303 added advantage of consuming less electricity.

Pumps are sized by gallons per hour (GPH) output at one foot of lift or height. Manufacturers usually offer charts that break downrepparttar 113304 power of each size pump according to incremental heights of one foot. It is recommended that you circulate your body of water at least once every 2 hours. Therefore you will need to size your pump to ensure that it has halfrepparttar 113305 GPH rating asrepparttar 113306 volume of your pond in gallons. For example, if you have a 1000 gallon water feature, you will require at least a 500 GPH pump.

Calculatingrepparttar 113307 proper pump for waterfalls is a bit trickier, because you must estimate your waterfall's height. To do so, you must measurerepparttar 113308 vertical height fromrepparttar 113309 top of your pump torepparttar 113310 top of your waterfall. In addition, you must add another foot of height or lift for every 10 feet of hosing you will be using (this will allow for loss of volume from resistance withinrepparttar 113311 hose). To calculaterepparttar 113312 required pump GPH, a general rule of thumb is that each inch of width ofrepparttar 113313 channel will require an extra 100 GPH. For example, if your stream or waterfall spillway will be 10 inches wide, you will need a pump that produces an excess flow of 1000 GPH at your waterfall's height.

Spring into Lawn Mowing

Written by Lillian & Dave Brummet

Ahh. Spring arrives withrepparttar beautiful twittering of birds preparing their nests forrepparttar 113292 unborn. What - can't hear them? The low rumble of lawn mowers not only drowns out natures' symphony, but also disturbs skittish wildlife and sleepy neighbors.

According torepparttar 113293 Environmental Protection Agency, some older gas-powered lawn mowers produce in one hour as much air pollution as a new car does in 11 hours. Lawn mowers newer than 1996 have to comply to new exhaust emission standards, which is a fantastic place to begin. However, these standards are not yet satisfying forrepparttar 113294 health ofrepparttar 113295 world.

Gasoline-powered mowers produce a cut that results in greater water loss and increased disease problems in lawns. Although many are now made with 4-stroke engines (much less polluting than 2-stroke engines), they still produce emissions.

There is a returned interest in push mowers due to environmental awareness of gas engine pollution and electricity use. Typically, crowded cities are resulting in smaller lawns, reducingrepparttar 113296 need for large, heavy mowers. Push mowers are light and easy to operate and, being much smaller, take up less storage room and do not pollute. These mowers are actually quite cheap and many stores are rising to meetrepparttar 113297 increased consumer interest. We have read that 7-blade models are considered better than 5-blade models.

There are other choices onrepparttar 113298 market than electric, push and gas lawn mowers. There are solar-powered models, too. We read of one featured in Omni magazine that operated on its own, travelingrepparttar 113299 entire lawn area duringrepparttar 113300 day and resting at night. It looked to be aboutrepparttar 113301 size of a vacuum power-head. Apparently, a special fence is used to keep it withinrepparttar 113302 lawn boundary and there is a built in alarm to prevent theft.
