While heading down to do laundry the other day, my neighbor was met with the sound of spraying water & a genuinely wet basement floor. She then immediately called out to her partner for help. She went down & shut off the main water valve but the water continues to pool on the floor, and upon further inspection, she found that the water was spraying from the holding tank of the boiler. There was no way to switch off the water that was coming from there so they simply tried to gather it in a bucket… My friend called for a heater repairman & was thankful that it was while I was in the autumn when they didn’t need to run the heat yet. The holding tank finally stopped spraying water when it was empty & then her partner looked a bit closer. There was a crack along the main line & she knew that it would need swapping. While waiting for the professional they went online to see about getting the area themselves. They learned that they could & that the replacement was fairly simple as well. The area was linked by bolts & seals so it didn’t even require any special tools. They ended up cutting back the repairman & ordered the parts themselves. Thanks to videos online & other online resources, instructional videos have made if simple to make minor repairs yourself at the time. If you are ever unsure of something, especially when it comes to something like your Heating, Ventilation & A/C system, you should typically trust a HVAC contractor.
