A cracked 1/2" MPT Short Nipple can cause a steady leak on the fitting connections of your Pentair Rainbow automatic chlorine and bromine feeders. A quick blow to the control valve on your system can crack the nipple.
Who is this for?
Pool owners who notice a slow leak on the original nipple. This likely indicates that you have a PVC nipple crack, but it's a cheap fix and worth having on hand before a full feeder teardown. Check the threads on your Short nipple and if you notice scuffs, you should additionally check for debris in the threading of the control valve.
*Always confirm the model of your product for compatibility before ordering any part. Please call Shasta Pool Supply if you are not sure and we will be happy to help.*
