The purchase experience was good. It took about a week to get the part and it appears that most of that time it was in transit. This is long but not a big issue.

There was no documentation that indicated that the valve had an input and output (i.e. flow direction). There also wasn''t any indication that the valve can be mounted in either a left or right orientation. As it turns out, there is an arrow on the valve that indicates flow. Additionally, there is a screw on the side of the valve that allows it to rotate allowing either left or right mount.

In the end, this is a good product with nice features and better documentation would make this an EXCELLENT product overall.

I read the reviews about this product. I was concerned about the "Solenoid not included" comment so I email the company. They quickly responded that the solenoid was included. I ordered the product. It does not come with instruction but there are only two wires and an in/out for the water which is marked with an arrow. Hard to screw up! Took me 20 minutes to install mainly because it''s hard to reach behind the water heater.

Bottom line easy to install, stopped the leak problem I had with the original part. What else could you ask for?

Both of the other reviews indicate that this is a solenoid valve assembly but it is NOT! The picture you see is NOT what you get. The picture is for the solenoid valve assembly (which is what I thought I was buying).

This particular product is the transformer. It was a stupid mistake on my part trusting the review and the pictures. Too bad shipping was $9.00, as now it''s not worth it to send it back.

15-day complicated return policy. The valve did not work. Must call seller to request for return authorization number; email was not good enough!
