I have a Laars LT250NS-C heater with a small crack to the header, beside the plumbing (see pictures).
It has been siliconed (caulked) and worked for a couple days then a small leak started. So i took off all the silicone and reapplied some more. I am not sure if i will hold or not.
I priced out replacing the header, and they want $750 for the part alone, plus installation. I live in Canada, and i cant find any online stores that would be any cheaper, and all the pool stores are similar pricing.
Has anyone run into a problem like this before? The material is a plastic (heat resistant), and i don't think silicone is the best material to stick to plastic. Does anyone have any other suggestions? Anything would be greatly appreciated.
