    Drain survey results query - money grab?

    I recently had a drain survey done as a soak away pipe at the front of the house is visibly broken and requires repair. As the house was built in the 60s I thought it may be beneficial to check out the whole system. There are no other obvious problems. The men who came to do the drain survey...
