Good if you can help me ... a new SAIAR 130 liter hot water tank was placed but it is an old model (20 years packed). the problem is that a little hot water comes out at times and then another time comes out .... I opened the faucets and pulled out double joints for the exit of AIR ... when purging a long jet of water comes out and it cuts off ... the water inlet has good pressure ... try to put a cable tape passes cable through the entrance and hot and cold water outlet but DOESN'T PASS ON DOES NOT ENTER ONLY SOME CENTIMETERS OF THE CABLE ENTER.

Hi Leo: Look, I don't know your model, but in some cases here (Mexico) I have been able to uncover them by putting air in them with the compressor, that if I put the air through the drain tap being disassembled, as I say is a comment rather than solution , because I don't know if it can be done on your model ...
