Tekleen Water Filter

The real story on the product and how it worked for these three companies.

Though seldom part of the original design, irrigation
systems need filtration to rid contaminants from the lines. This ensures that
plants are being watered properly and reduces the frequency of irrigation
system maintenance by preventing small particles from progressing through the
nozzles to plants.

“Filtration is a must with drip systems,” says
Gideon Brunn, president of Automatic Filters Inc. “Otherwise, the nozzles
are constantly clogged.” Tekleen Water Filters take the maintenance out
of the process because they are self-cleaning.

The line pressure at the filter outlet drops after dirt
settles on the screen. As the pressure reaches a pre-set differential, it
triggers the backwash cycle to begin. The vacuum nozzles suction dirt from the
inside of the screen and flush it out into the drain. All of this is done
without interrupting the main flow and requires only two gallons of rinse
water, making it both production- and environmentally-friendly.

“You are not flooding the area with a lot of backwash
water like a lot of other filters. For example, a 2-inch filter would use two
gallons of water per rinse. Other filters with a 2-inch flushing valve would
use 20-30 gallons of water,” explains Brunn.


Installation is simple — attach the filter to the line
and turn it on. Aldridge Nursery, Von Ormy, Texas, purchased three additional
Tekleen filters after being so impressed with its first one. Its oldest filter
was purchased in 2000 and has not needed any upkeep. “We did some things
when we first got it that we thought we needed to do, like take it apart and
clean it, and we found out it wasn’t necessary,” says Ralph
Simnacher, owner. “We thought we knew more than the instructions.”


Ulery Greenhouse, Springfield, Ohio, has had the filter for
about 1 1/2 years, with no major problems. “They only thing you have to
do is change the battery in it once a year, because it automatically
backflushes,” says Ashley Smith, grower.

The only required maintenance is to keep an eye on it.
“To make sure the machine is functioning correctly, you have to make sure
that you monitor your inlet and outlet pressures. Make sure that the flushing
system is working correctly. It’s fully automatic, but you should keep an
eye on it to make sure that it’s properly working,” says Rick
Ruggeri, part owner of Silver Terrace Nursery in Pescadero, Calif.

Silver Terrace Nursery uses three Tekleen filters to back up
the sand filters at the reservoir that serves as the nursery’s main water
supply, and they report no problems to date. “We haven’t had to
maintain them up to this point,” says Ruggeri. One thing Silver Terrace
Nursery did decide to do was to take out the battery and use 110-volt
controllers. “So they’re basically self-sufficient, and you
don’t have to mess with a battery,” Ruggeri says.

With advance notice, Automatic Filters can provide filters
that are pre-fit for controllers. Options include 220-, 110-, 12- and 9-volt
controllers. Automatic Filters Inc., Los Angeles, Calif. style="mso-spacerun: yes">  (310) 839-2828.
