Half a year ago, he replaced the magnesium anode, but it seems he bought a fake. The anode is attached to the bottom, the thread of the M8 stud. In general - a hole in the bottom of the tank under the M8. But in order to crawl there, you need to pull out the ten and climb inside with a children's hand, the hole from the ten does not allow.
So, I noticed that after turning on the water, the boiler began to drip. removed the temperature controller - and water drips from the stud. I thought that an air valve was dripping at the top, as it already was. He touched the anode stud - barely holding on. still stirred - and kaaak banged - a fountain for the whole bath. Slap all the remnants of the anode. Well, they immediately blocked the water, while I plugged a hole with my finger.
Question. how can I close the hole without getting into the tank?
Do not offer the option "hammer a wooden chopik". Maybe there’s some thing like a moth?
