7 Replacement Hygroscopic Discs<br>For Rain Bird Wired Rain Sensors (Model RSDBEX & RSD)<br>Rain Bird No Bracket Rain Sensors (RSDCEX)<br>And<br>Rain Bird Wireless Sensors (All WR2 models)<br>Brand New replacement hygroscopic discs for Rain Bird Rain Sensors.   If your Rain Bird Rain Sensor is not working well, the likely cause is that your discs have weathered over time and are not functioning properly anymore.  Instead of throwing away the entire sensor, just remove the spindle and cap and replace the worn out discs with these 7 new ones.<br>The way this rain sensor works is that when rain hits these discs, they expand and push a switch off that is connected to the controller.  When it stops raining and the discs dry out, they contract back to the original size and release the switch.   If these discs get excessively dirty, are more than 4 years old, or have bugs living in and around them, they might not function properly.  This is a simple tool free fix that should take no more than 5 minutes.<br>This auction contains enough discs to repair one Rain Bird rain sensor.<br>These discs are from a different manufacturer from the original discs that Rain Bird used.   There should be 6 discs on your sensor that you need to replace.   These discs are thinner than the original Rain Bird discs and that is why you need 7 to replace them and have the sensor function properly.   The inner diameter and outer diameter of the discs are identical.   I have done testing of the thickness of these discs before wetting, after wetting, and after drying out to make sure that the sensor will perform the same as it did when it was brand new.   These replacement discs are high quality OEM hygroscopic discs from another manufacturer of irrigation rain sensors.<br>SHIPPING OPTIONS:<br>FREE SHIPPING (USA only, NO TRACKING)<br>This will be shipped in a standard mail white letter envelope and arrive in your mailbox with your regular USPS mail.<br>There is<br>no<br>tracking<br>included with this option.<br>Due to COVID and recent USPS Delays, this option could take up to 12 business days (not including holidays or weekends) depending on where you are in the USA.  All items ship from North Carolina.<br>Ebay's guaranteed delivery date may not be accurate as it doesn't take into account weekends, holidays, and typical parcel post shipping methods.<br>If you need the delivery of the product fast and/or a tracking number, please choose the USPS first class package with tracking for an additional $3.25<br>USPS FIRST CLASS PACKAGE WITH TRACKING (USA only)<br>USPS first class package with tracking is $3.25 for the first item and $0.25 for each additional item ordered.<br>This will typically take 4-6 business days for delivery.<br>The item will be shipped in a poly bag and arrive with your USPS mail.<br>INTERNATIONAL SHIPPING (NO TRACKING)<br>International Shipping will be $3.75 for the first item and $2.00 for each additional item ordered.<br>These will be mailed in a standard white mail envelope.<br>Due to COVID and shipping restrictions, please allow 4-8 weeks for delivery.<br>************************************************************<br>You Tube Videos!!<br>I have put some YouTube Videos online showing how to change out these discs on Rain Bird Rain Sensors...<br>Changing out Discs on RainBird WR2 sensor:<br>https://www.youtube.com/watch?v=9S4ArPkXe8o&t=30s<br>
