I own a Sundance Optima spa and was receiving a Flo warning on the control panel as well as a red light (as opposed to the normal white light) on the outside of the spa. I knew that I was still receiving flow inside my spa so it probably was not the pump. I purchased this flow switch and installed it in about 10 minutes and fixed the problem.

Fit, works great, solved the problem.

easy replacment

I really like this sight always find what I'm looking for with great prices and quick deliveries.

Works perfect cost was low

Ordered my flow switch, three days later it arrived in the mail. Took 30 min to install and fill. Works like a charm. Wife's happy.

Took about 15 minutes to install with no problem

OEM part number search on Google generated a link to the Spa Depot product I was looking for. Clear and accurate description gave me confidence to buy knowing part would fit. Price was fair - shipping reasonable - over all great online purchasing experience. Would recommend this vendor to any DIY'er searching for parts.

In Stock , reasonable price, Fast shipping!

Just what I needed. spa is running great.
