WebMar 8, 2016 · Total of 60.4 added equivalent feet of straight pipe. To convert this value to feet of head, multiply 60.4 ‘ by the same number used in the length of pipe calculation above for 70 GPM and 2’ PVC diameter pipe, 7.76 per 100’ of pipe. 60.4 / 100 x 7.76 = 4.69. Total of 4.69 added feet of head for connectors. WebSeveral manufacturers have developed gravity filters that are backwashed automatically at a preset head loss. Head loss (water level above the media) actuates a backwash siphon and draws wash water from storage up through the bed and out through the siphon pipe to waste. A low level in the backwash storage section breaks the siphon, and the ...
