Well our anniversary is in just a few days, and we have started the beginning of our celebrating with an annual event-switching of the drain field.
When we built the house 11 years ago the drain field was finished around this time. The guy who installed it installed a split trench system - meaning there are two fields that have to be rotated from year to year. He gave Dan the tool and told him to make sure he remembers to switch it every year. Eleven years ago when I mentioned that we should switch it on our anniversary, Dan was mad.
But we have never forgotten, and switching the field is an annual reminder that not everything about marriage smells like roses - sometimes things stink a bit!!! ( you see what I did here don't you - smell-drain field.)
