Hi.
Any ideas on a reasonably priced and effective way of having a drain pipe unblocked:
It's the lower 3 feet that feed the ground drains (no other adjacent way of access, as it is then in a drain under a concrete path before joining the sewers). This section is made of cast iron and cannot be removed. It's full of several feet of silt/sand from sand-faced roof tiles and is completely blocked, preventing rain water passing through.
Discovered this by removing the plastic drainpipe section above, to discover that the cast iron section was blocked all the way down by probing with a lamp-pin.
Grateful for any good advice.
Thanks.
