Since there isn't an electrical current going through sprinkler wire, it's just a single pulse that gets sent from the controller to the individual valve, is there any reason to waterproof crimp underground sprinkler cable after it's been cut in repair.

If the answer is No, Then why?

If the answer is Yes, Do you have any suggestions how best to seal and/or waterproof the spliced cable.

Thanks!

  • Your contention that "there isn't an electrical current going through sprinkler wire, it's just a single pulse that gets sent from the controller to the individual valve" is incorrect. The controller sends low voltage current (commonly 24vt) to the sprinkler valve solenoid for the entire duration of the set activation time for that station. – Jimmy Fix-it Jul 14 at 16:46
  • Interesting! didn't know that. does it depend on the type of controller or all of them send low voltage current? – Sickest Jul 14 at 16:53
  • All of them. Your "pulse" idea would require a much more expensive "latching" magnet valve, I.e. the magnet valve version of a GE RR7 relay, with diodes to allow polarity reversal to confer on/off. These would also be much more prone to sticking on. – Harper Jul 14 at 17:08

    @jsotola I got butt splice connectors with shrink wrap on the sides. – Sickest Jul 14 at 18:10

Yes, because a poor connection due to subsequent corrosion can affect the signal which may well cause unreliable operation.

There are waterproof junction boxes available which you should use.
