A:  No, I have never seen this sprinkler with a 1 inch port. However, I might add that in my opinion this is an excellent sprinkler that can be adapted to any pipe size.  I presently have 62 of these sprinklers on my property so I am very familiar with them and they perform well.

A:  I don't know. Look it up.

A:  K-Rain does not make a 3/4" female to 1/2" male adapter/riser. The Home Depot should carry this adapter.

A:  Sounds like you have an issue with the valve not completely closing when that zone times out. I don’t think it is the sprinkler.

A:  The K2 Pro does not have a Check Valve or other device in the head to prevent low head drainage, which is defined as water left in the piping after the system shuts off draining out of the heads in the lowest areas of the system. Low head drainage should stop on its own after a few minutes, if it does not, this indicates a leak from the systems water source, usually a solenoid valve that is failing too close all the way. There are Check Valves available to be installed in K2 Pro that will prevent low head drainage, these are part number P16009110. However, make sure that the heads are not leaking continuously as this is not an issue the Check Valves will remedy. Please reach out to Mike at K-Rain ext. 129.

A:  If you have 5 new heads that are leaking (flowing water) after the timer shuts down that zone, then you most likely have a zone control valve that is faulty and not fully shutting off the water flow to that group of heads. The heads do not have internal valves to shut off water flow. That is the job of the zone control valve. Buy an inexpensive parts kit to repair the zone control valve. Hardest part is to find the zone valves which are typically buried in groups.

A:  I got this answer from K-Rain tech support: There is a small weep hole on the side of the pop-up riser that flushes soil away from the base of the riser. This is to prevent abrasive soil from scratching the riser as the riser pops up and retracts. When the riser becomes scratched it will wear down the riser seal much more quickly than a smooth riser. A head with a worn seal will leak excessively around the base of the pop-up riser. If the weep hole has water spraying out it is a defective head, but slow leakage is normal.

A:  Yes this is a normal

A:  Not sure of answer. I will have to check next installation since my operation is underground now.

A:  IT is defect

A:  It should not be doing that.
