<{POST_SNAPBACK}>Make sure he didnt use land drainage ducting for the perculation piping.. huge commen mistake!!! its designed to take in water not release it! Best is to use 4" wavin sewer pipe and cut with a consaw.. Cut about half way through every 4 inchs across the width of pipe, and have the cut side faceing down to the gravel.. each pit must be at least 15 meters long with a vent at the end. piping must be nearly level!you also need about 3ft of pee gravel under each of the 4 perculation areas.and dpc over the piping to stop too much garden water and dirt fom clogging up all the soat pit.. also get the tank serviced
Thanks for the advice, il have to bounce all these ideas off my father, his head will be wreaked
. I dont tink theres much servicing to this system, shit goes in water goes to perculation area.It was badly built from the start because the stuff coming in just breaks the seal on the top and this is killing off the bacteria and causing the pipe to the perculation area to clog and the fact its over 25 years old doesnt help
. doing a newperculation area like you mentioned would be the way to go
