Hello lovely TESsers. I am trying to sort out my water butt. I have various bits of drainpipe but before I go ahead an balls it all up could you please help me with these questions. 1. What is the best way to cut drainpipe? Can I just use a saw? 2. How do I join two pieces together? I'm talking about the bits that kind of slot inside each other - Is there some sort of adhesive that I should/could use? 3. How long should the bit that goes into the drainpipe be? Should it go just inside the water butt or near to the bottom, halfway even? Thanking you all in advance.
