Why is my miami lazy spa leaking from air conpressor underneath? And works for tiny bit then turns off?

the outlet you are powering it with is too low in amperage to run the spa or the pump is shorted or seized

or shorted heater element

damaged pump

did you narrow down what is leaking if seal is it tight enought or sitting wrong or damaged is it the pipe cracked hole etc or is it the spa liner / connection --and if told to bring back to shop why not doing so

clean out the filter before the pump

what do you mean by flooding?
if it is overflowing?
try to remove the 4 screw underneath the carb,
take out the diaphragm,and then followed by float valve..
there is a tiny spring,be very careful...
stretch the spring a lil bit more at about 2mm...

as time passes,the diaphragm deteriorate and one way to correct them is by stretching the tiny spring to give more strain on the diaphragm...

this is what i did if i am too lazy to go out and buy the diaphragm kit..
only 10 bucks...hehe
