Hi, thought it was time to check my drains again but instead of crawling around on the floor to check the drain exit pipes I fed a small hose down the side of the roof & poured a litre or so of water through it.
If it pours freely underneath the car then you have clear drains, if it stays dry underneath or only seeps out you have an issue & need to crawl around!
