Parafien primus (blow torch) does not built pressure inside when pumping. Trying to pressurising it buits pressure on the downward cycle but with the upward pull it sucks the air back. Is there a diag
I believe it is the pressurising system which is not working properly-leather seals but also don't know whether all seals is fitted inside

A bladder tank is a water storage tank that is used to allow a pump to compress air inside the tank. Water can't be compressed so the tank is built with a bladder or balloon inside that allows the pump to be able to build up pressure inside the tank. This allows a pressure switch to turn on or turn off the pump. Typically if the bladder goes bad inside the tank the pump will cycle rather frequesntly.
Depending on how much freon is in the system, it could be a faulty low pressure switch or a faulty clutch. You would jumper the low pressure switch to eliminate it for a test.
internal pump failure....check that it is not blocked ...the water supply hose only fills tank then the pump pust pressurised water to the spinning arms.
IT'S AN INTRINSIC FAULT WITH THIS PIECE OF JUNK. THE DIAPHRAM INSIDE THE PUMP TUBE IS ABSOLUTE GARBAGE, THEY DON'T EVEN WORK PROPERLY WHEN BRAND NEW, BUT AFTER A FEW MONTHS THEY WON'T PRESSURISE AT ALL. BUY A QUALITY SPRAYER, THAT REPLACEMENT PARTS ARE AVAILABLE FOR.
if you see the water leaking form the front side of the engine usually from the water pump since the pump is not running you also wont get heat, bit when you pressurise the sys you are forcing the hot water into the core and you have heat, it is the water pump.
You may need to ask AAA to put a radiator pressure tester on the resevoir bottle and pump it up to operating pressure(Pressure cap rating) and see if it over pressurises while it is running at operating temp,rev engine up and down and watch what the testers pressure readings do,it should move up and down in sync with the water pump.If the pressure keeps building i would have to believe that combustion chamber gases are over pressurising your cooling system.Also test the pressure cap is functioning within factory specs.
Are you losing water from the radiator or expansion tank and need to keep topping up? Did the fault occur before the radiator & thermostat were replaced or only since?
