i made the mistake of storing my pw in a shed that was supposed to be heated to 50deg, over the winters , as i haven't used my pw in a few years i finally got a pw job last month , did a car wash
but what i found was the pw had froz up at some point ,, my falt for not putting antifreeze in it ( that will never happen again ) any way my pump needed to be rebuilt i got that done did my little job , i had bypassed the burner as i wanted to go threw it first ,
well i hooked up the burner and yep coil leaking like a sieve , i disassembled it and put the power to it again and found the leaks ( this is the point i should of took pics ) i checked for new one but not going to happen ,,,,for 650 what i was told ,
anyway i pulled the coil all the way off and got up in the inside and re welded the crack , tested it and had a 2nd crack under the 2nd set of inner coil , so i ground off the welds that held it cut the pipe off and pulled the inside mini coil out welded the leak slipped a sleeve over where i cut the pipe and welded it up .and put her back together ,
just got done with my test on it and it seams to hold well , i flushed out the kerosene in the tank and added new , and after a 1/2 min on go's the burner just like new ,
i still have to test it under 4000 psi but it works well under 2500psi
did i say i will not forget the antifreeze this year ,
thought i would add a pic of my rig
