I will order from SpaDepot Again!

I ordered two pressure switches from SpaDepot for my really old Coast Spa. The switch I had was no longer available so I contacted the manufacturer and they game me some alternatives. SpaDepot had them in stock so I ordered two different ones just in case. Response from them was good, website was easy, shipping was fast. Parts came as presented. Packaging was safe. Tracking was easy. First one worked, second is a spare. No worries recommending SpaDepot.

Perfect replacement

My pressure switch on my old 1999 Great Lakes spa started needing regular adjustments to keep the spa running. I took a picture of the old pressure switch and sent the info to The Spa Depot to see if they could recommend the proper replacement for the no-longer-available switch. The CSR responded quickly with this replacement switch which works perfectly!

excellent fit

it fit my OLD 2000 imperial spa hot tub perfectly. the numbers on the devices were different, but the appearance was exactly the same so I took a chance and ordered it. it had 2 contacts placed between 2 white plastic shields, just like my original. but it had a stainless steel threaded part that was screwed into the heater body, where my old original one had black plastic threaded part. cross threading and subsequent leakage was now not a problem. the circulation pump fired right up and began blowing air bubbles and water into the hot tub immediately after I switched on the power and watched the pressure valve instantly respond . I will soon order another as a back up..i don't know how long they last..but this old one was maybe from 2000? wow! thanks spa depot good product good match!

Electrical connections

Be careful with the electrical connection on this part. The copper tab in the NO connector snapped off on the second time it was connected. I had to remove the connector to tighten the part on the heater. When I pushed on the connector it bent and snapped. It is much thinner than the tab connection on the original sensor.

Nice and easy to replace.

I wasn't sure the switch was the problem but for the price decided to replace it. I didn't even drain the water. Just disconnected the wires unscrewed the old one and screwed in the new and reconnected the 2 wires. Of course I had turned off the power to the tub. Some water spurted out but less then a quart. Has been working great since then.
