Keep spare 20" whole house housings
It seems the 20" whole house filter housings only last about 5 years. I know the clear polycarbonate ones crack really easy so I changed all mine to the blue ones. I have now had the blue ones crack. My pressure is at 62 and never goes over 68 and they are not in the sun. I believe part if the cause is the weight of the wet filter inside the housing. These are really heavy when wet. So the bottom of the housing is bearing all that weight. I will say Express Water did get me new ones fairly quick. Keep spares on hand. Just makes a mess when they crack.
