Shipping Questions

1.       How quickly can I get my parts?

Place your order by 12:00 Noon (Central Time) & your order will ship the same day (M-F). If it is being shipped to Texas or Oklahoma , the parts will be there the next day.

2.       Can I ship to the job site instead of my office?

 

Yes, just fill in the "Ship To:" address with the 911 address of the job site. UPS & Fed Ex Ground will deliver to those addresses.



Returns

If the product is defective or we ship the wrong item, call to get a Return Goods Authorization #. We will schedule a pick-up and either credit your account or replace the item. There will be a 25% restocking fee on all other returns and you pay to ship the item back to us. Product returns will be accepted only in unopened packages and with an RGA#. Shipping charges will not be refunded. Chemical analysis products are NOT returnable.

Chemical Analysis Questions

1.       What dissolved oxygen concentration should be measured in the aeration chamber of an aerobic treatment unit?

The dissolved oxygen concentration that should be measured is at least 2.0 ppm or mg/l. Aerobic conditions do exist within a liquid with a dissolved oxygen concentration of 1.0 ppm or mg/l. However, a dissolved oxygen concentration of 2.0 ppm or mg/l is recommended.

 

2.       What pH range should be maintained for good growing conditions within a treatment system using microbes for treatment?

A pH ranging from 6.8 to 7.4 is excellent for the microbial populations providing treatment in residential onsite wastewater treatment systems.

Subsurface Drip Questions

 

1.       Can Bioline be installed in freezing climates?

There are hundreds of Bioline systems installed in the cold climates of North America without any reported failures of the drip fields due to freezing. Since Bioline dripperline drains after each dosing cycle, there is little effluent left in the tubing to freeze. With good ground cover such as grass or snow, the ground remains above freezing temperatures at the dripperline.

 

2.       What about plugging?

Bioline emitters are designed with a unique self-flushing mechanism that pushes small particles through before they can build up and cause a problem. Each emitter is impregnated with Vinyzene, a chemical that prevents the potential clogging formation of microbial slime.

3.       Is root intrusion a problem?

Coupled with the frequent dosing cycles of wastewater dispersal, a barrier in each Bioline emitter helps prevent root intrusion. In fact, Netafim guarantees Bioline against clogging from root intrusion for a period of ten years, without the addition of other chemicals.

 

 

Water Meter Installation

1.  Can the water meters be installed at an angle?

Yes, the water meters may be installed horizontally or vertically. The manufacturer says they may also be installed at a slight angle as long as they are at least 1 foot after the bend in the pipe.

2.  What are NPT threads?

National pipe thread (NPT) is a U.S. standard for tapered threads used to join steel or brass pipe and fittings. The taper on NPT threads allows them to form a seal when torqued as the flanks of the threads compress against each other, as opposed to straight thread fittings or compression fittings in which the threads merely hold the pieces together and do not provide the seal. However a clearance remains between the crests and roots of the threads, resulting in a leakage around this spiral. This means that NPT fittings must be made leak free with the aid of thread seal tape or a thread sealant compound. (The use of tape or sealant will also help to limit corrosion on the threads, which can make future disassembly nearly impossible.) Sometimes NPT threads are referred to as MPT (Male Pipe Thread) or FPT (Female Pipe Thread), for male (external) or female (internal) threads, respectively. An equivalent designation is MIP (Male iron pipe) and FIP (Female iron pipe).

3.  Is NPT different than schedule 40 pipe?

Yes. Nominal Pipe Size (NPS) is loosely related to the inside diameter of schedule 40 pipe. Because of the pipe wall thickness, the actual diameter of the threads is larger than the NPS, considerably so for small NPS. Other schedules of pipe have different wall thickness but the OD (outer diameter) and thread profile remain the same, so the inside diameter of the pipe is therefore different from the nominal diameter.

Spray Head Settings

1. How do I change the rotation of my sprayhead? 

A) FIND THE LEFT START POSITION: First rotate the turret with your fingers around to the RIGHT (clockwise) until it stops. Then, rotate the turret around to the LEFT until it stops again. This is the LEFT START position. The sprinkler will begin spraying from this point and will rotate clockwise.

B:)To INCREASE THE ARC, insert the K-Key into the arc indication ARROW SLOT at the center of the turret. While holding the turret with your fingers (so that it doesn't rotate), turn the Key CLOCKWISE, until the arc indication arrow points to the arc desired.

To DECREASE THE ARC, hold the turret, and turn the Key COUNTER-CLOCKWISE to the desired arc setting. ( IMPORTANT: DO NOT TURN THE ARC INDICATION ARROW PAST THE 360 SETTING OR PAST THE 30 SETTING )

C:) TO ADJUST THE ARC WITH THE SPRINKLER ON: If the sprinkler is turning to the right, hand-spin the turret to the right until it stops. Then, turn the turret to the left until it stops again. THIS IS THE LEFT START POSITION and you can now turn the arc indication arrow to the desired setting. If the sprinkler is turning to the left, hand-spin the turret to the left until it stops. IMPORTANT: DO NOT TURN THE ARROW PAST THE 30 SETTING OR PAST THE 360 SETTING.

2. How do I change nozzles on my sprinkler?

A.) USE YOUR KEY: After you remove the nozzle retention screw with your K-Key, insert the Key into the keyhole on top of the turret. Then, turn the k-key 1/4 turn so it doesn't slip out of the hole when you pull it up.

B.) PULL UP THE RISER: Firmly pull the entire spring-loaded riser with the key to access the nozzle socket. Hold the riser up with one hand.

C.) REMOVE THE NOZZLE: With the nozzle retention screw removed, insert the K-Key into the slot directly under the nozzle "prongs" at the top of the nozzle. Now, pivot your key 1/4 turn to "hook" the nozzle and pull the nozzle out.

D.) INSTALL A NEW NOZZLE: Press the desired nozzle into the nozzle socket. Make sure the nozzle number is visible and the nozzle "prongs" are up. Then re-install the nozzle retention screw. NOTE: The nozzle retention screw is also a break-up screw and adjusts the distance of the spray.
