Ok so I bought a house in Decemeber that had a hot tub used it maybe twice before the heating went out on it .
always was very dirty so I just tured all power off to it and finally just now got a chance to clean it up and everything cause the thing was a tad on the dirty side in my opinion and needed a good scrubbing .... I noticed an area where it looks like a hole/crack might of been attempted to be repaired not sure what he used but as I cleaned it alot of the repaired area was chiping away and also in cleaning i steped in one area made a hole and another and a small crack so now that I have the thing drained and cleaned I would like to know is there anything to repair cracks/holes in hot tubs or ideas on how I might do this. I took out the filter and it was just nasty as you will see in the pics I will add and the inside where the water sits I still need to clean it out cause it is also filthy. but my main questions I would like answered are as followed
#1 So my heating went out I read a little and saw that this could be something simple as just hitting a switch cause the tub got so dirty it kicked it off or something of this nature i'm hoping that is it and not call a tech for repair cause I read how expensive this can be and I have no clue what type of hot tub nor brand model anything to be honest hoping I can get that answered also
#2 how do you fix cracks/holes in your tub
#3 how do I drain this thing completly cause I know it's still holding water that I couldn't drain with the sump and the water coming out the hole is filthy
#4 what chemicals/how much of do I use i'm completly in the dark hoping with this and these pics I can get some idea of where to start to begin getting this thing back to running it was nice the first 2 times I used it lol
