The hot started leaking. Took the side panel off the tub and noticed that water was dripping from the unit. Because the unit was previously attached to the coil pipe I had to bend the electrical tabs up to get them out of the way. No problem. Luckily the label was still on the unit looked online and there it was shown and at a fair price. Needed some help form the supplier but he set me up so that the installation went as expected. Turned on the tub and the waters are flowing again. Have not needed the adjustible part of the unit but it works .
