Tools Needed


Filter head was cracked at the air relief valve.

Written on 1/17/2021 by Guest

I replaced the filter head as it was cracked at the air relief valve and pressure gauge. Because it was so inexpensive, I thought it best to replace the air relief valve at the same time.

Were these instructions helpful?
