专业人士是这样修的
Any repair work should begin with detecting the exact location of the leak and draining the water tank thoroughly. Since any repair yields the best results on a clean surface, we make it a point to thoroughly clean the tank to eliminate any loose dirt, oil, paint or grease. Only the bare plastic should be exposed.
The next step is to drill a hole at either end of the crack and a tiny drill bit to prevent the damage from expanding. Once that’s done, we’ll repair the cracked area using a heat gun or propane torch. Usually, some of the adjoining rooms are also heated to ensure uniform heat distribution over the entire crack.
We’ll then carefully place the required amount of polyethylene filler material on the crack. At the same time, the heating will be slowly continued to melt the plastic and fill the crack. Generally, a flat-headed tool (like a putty knife) is used to flatten the filler while any excess material is trimmed off.
We’ll refill the tank to check if the leak has been adequately repaired when the area has cooled down.
