    Burping sink
    Every time my central heater comes on, the kitchen sink starts "burping" sounds and continues until the heater goes off. Help, please!

    Tell us more about this "central heater" Is it a water heater? A furnace? And what "burps" in the sink. The drainage down in the trap? The water coming out of the spout? Please give us more details. Tom

    It is an electric central heat system--uses no water. The burping sound appears to be coming from the trap in the kitchen double sink. There is no apparent connection to the heating system, but that is when the burping sound is heard--when the heater is on. The burping sound is only in the kitchen, not in the bathrooms.

    You also replied to my sulphur smell question. What can safely be done about it and what might be causing the grayish looking hot water in the tubs?
    Thank you for your interest and help.

    Ther's no connection between the electrical system and the drainage in your home. I don't see how one could affect the other. Burping in trap indicates a blockage on down the line. If it were a gurgle you woul have a blocked vent. Are you sure it's a burp? I'm still attempting to figure out why a electric heater turning on would affect your sink. Regards. Tom

    It's a weird & convoluted problem , so there must be a weird and convoluted answer.

    The only tie in I can think of is if there is a floor drain/ laundry sink near the heater. If the cold air return for the heater draws only from the furnace room & if the furnace room door is closed & if the drain is dry, then perhaps air is being drawn up from the plumbing system when the fan is on? I suppose a venting problem could lead to air being drawn through the kitchen sink. That is a lot of 'ifs'!
