Easy to install and the right part!

Had to replace a defective pressure switch. The switch installed easily. Using a new pressure switch cable, it fit perfectly to the Gecko control board.

Micro pressure switch upgrade

The old micro switch is plastic, this one is great because it's metal. Be wary of that fact when removing your old switch. This is a larger micro switch than used on Hydroquip remote heaters but should fit. Spa Depot is great at sending parts quickly as well as honoring warranty claims. That's the number 1 reason why they are my main parts supplier.
