I bought a whole house carbon filter about 4 years ago and recently I noticed hairline cracks in the neck where the valve screws in and water was slowly leaking out. I contacted the website where I ordered the tank and they had a new one sent out promptly. But I noticed on the new tank there are already hairline cracks. Is this normal? It seems like the valve cap they used during shipping was on quite tightly and I'm wondering if it was screwed in too tight and caused these little cracks. I'm wondering if I should even bother installing this. Curious to get your thoughts. Attached a picture of the new tank and also the old leaking tank.
