This is great, so glad I asked. It's obviously not just me. What I find really bizarre is that the guy who sold me my boat (with pretty much full service history since it was built in 1989) didn't run through this with me. He wrote notes about a few things but there have been a lot of little mysteries! Slowly getting to grips with it all

Great! Thanks both, that's really helpful. I'll check out Aquafax now.

I’m a new boater and tried doing my own pump out for the first time at Alperton, West London last Saturday (I’ve previously had someone do it for me once at Willowtree Marina). I'm confident the tank was full but couldn’t get the nozzle to achieve good suction. Do people generally expect to carry a pump out adapter? I've seen some online this afternoon and wonder if this is standard kit that most pump out owners carry? I can order one but it won't be here for a few days and I'd like to have another go at pumping out over the weekend. Currently got a porta potti on the go. Any advice welcome! Thanks.
