Not sure if this is the right forum to post this, but I'll be building a small retirement place in the country in SC and will need to install a septic system. Has anyone here installed the "infiltrator" as opposed to the traditional pipe and rock system? Is the jury still out on infiltrators? They seem kinda flimsy to me...and they only have a five year warranty, which seems oddly short and doesn't build up my confidence in these systems. Educated opinions, anyone? Experience with either/both as an installer or owner? TIA!
