## Questions & Answers

**Q: How many in line valves can this power simultaneously?**
A: As many as your control box supports.

**Q: My old transformer - which hit the floor and broke, shows output of 26.5 - will this still work?**
A: The only difference was I had to cut end of to direct wire. My older system did not have a plug but the transformer worked great.

**Q: Will this work on a rain bird controller #esp-m?**
A: I don’t know the specific model of rainbird system you have.  If your existing transformer uses two wires, then this will definitely work.  If it has three wires then it may or may not work and the hookup is different for these controllers and this hookup is not discribed in the literature.

**Q: Will this work for rainbird stp6pl?**
A: Yes, it will work that controller.

### ⭐⭐⭐⭐⭐ Works fine
*by D***A on August 25, 2025*

Works fine!

### ⭐⭐⭐⭐⭐ Excellent buy! Saved big money to buy replacement cord versus whole new Rainbird timer.
*by K***N on June 9, 2025*

Perfect OEM for our rainbird sprinkler system! Power cord wore out from many years in a hot garage! Sprinkler system up and running thanks to Amazon as these cords are not available at Home Depot where we purchased the original unit.

### ⭐⭐⭐⭐⭐ Great replacement part
*by V***T on December 13, 2024*

Replaced broken transformer on Rainbird system; works great and much better price than ordering directly from Rainbird.
