Diverter Valve Leak

Problem

I noticed that the hot tub temperature was low (80F) so I went to check on it. I then discovered that the water level was below half way. The pump was still trying to move the water around.

Checking the outside of the hot tub revealed the leak was on the same said as the main diverter valve. The main diverter valve had a small leak in the past  but I let it go since it seemed to be leaking into the hot tub and only when on high. It seems that it found a way to make things more exciting for me. 

Removing the side panel revealed the water but no noticeable leaks so I assumed it must be the leaking diverter valve.

An inspection of the electrical revealed that the fuses for the heater had blown.

Fix

Doing a valve replacement for this particular valve would be tricky since it multiple pieces all glued together. So, since it is winter, the fix will be to use a 2" (size 12) plug. And done!

Since the old fused jumper cables were kinda melted, I made new ones.

Done!

Revised Fix

So, after the winter, I noticed rust from the above plug so I decided a more permanent solution was required. I had purchased a 2" plug but it was a bit too big for the hole. I will need to resize it.

Using a heat gun, I applied heat to the perimeter of the plug for about 2 mins while rotating the plug. After that, I pushed the plug into the hole in order to get it to resize itself to the diameter of the hole. Once cooled, I removed the newly formed plug and applied primer and glue and secured in place.

No more leak. Done.

Wired Remote Removal

The stereo's wired remote had become an eyesore so it was removed. Covered with a 3d printed 65 mm cover and siliconed in place.

Pillow Fix

The pillow kept coming loose and floating around the hot tub. Decided to re-form it with a heat gun and some zip ties. Worked perfectly.

New Remote

Since I have a custom controller, I decided to add a control panel to the hot tub. The plate was created using a 3D printer and PLA light grey filament. It was then sanded smooth. The center switch controls the lights and the small switch to the left controls the pump. All other controls are set using HomeKit.
