I had to replace two older filter housings that simply disintegrated due to exposure to the sun. Those plastic filter housing were purchased and installed in 2010. They lasted until early 2024 when one housing filter simply split open under normal operating conditions spraying water for hours. The cause of the split was simple degradation of the plastic due to exposure to normal sun light.The original cost of the original filter housing was probably 1/2 the cost of the new stainless steel housing. The fact they had to be replaced after 14 years and the replacement cost of new plastic filter housing was only $30 less than the stainless steel filter housing makes it obvious that the new stainless steel filter housing is far more economical over time.
