Repairing water spout on plastic tank
My overflow spout cracked on my water tank and this is one way to fix it.
Get 2 washers with holes large enough to fit over the spout.
Hold the first washer with needle nose pliers and heat with a small torch.
When it's good and hot slide it over the spout and press it against the tank so that it welds itself to the tank. Let cool.
Run a thick bead of silicone around the second washer and slide it over the spout just till the silicone starts to squeeze out.
Leave it for 24 hours if you can.
