This is all great info. I have gone for the 6mm as I'm pretty sure I can deal with the 1.26W drop and I know the MC2 connectors are definitely going to be compatible. Thanks all for your advice.

I'm planning on adding 3x165w (Imax: 4.72A ISC: 5.18A) solar panels to my 12v system and mounting them at the front of my boat. This will put them 11m from where the MPPT controller will be mounted. Not ideal I know... I've been told that a 6mm solar cable will be sufficient but as I have found some 10mm at £1.35/m I am considering going for the thicker stuff. Can anyone give me any reason why I shouldn't go for the 10mm cable? Or maybe more specifically why I shouldn't go for this stuff in particular? http://quickbit.co.uk/10mm-solar-cable Thanks in advance. Alex

I have gone with the vetus hose adapter. Thanks for all the advice.

Just checked out the koi carp pond equipment route and it looks like I would have to stack up a couple of reducers. It would be perfect but unfortunately it is in quite a tight space so dont have much room to turn it around in. Blackrose - Could you give me the name of your chandelry? Working an angle in to the reducer might just do the trick. Thanks again!

My Rule Shower sump pump has just given up the ghost and I am in the process of finding a replacement. After a spot of research it looks like the Whale Gulper 220 is the pump of choice so looks like that is going to be the one. The only problem is that it has a 19mm input and the drainage pipe from the shower is 38mm... I cant for the life of me find a 38mm to 19mm reducer though. Does anyone know where I might be able to find one or possibly have an alternative solution? Cheers.
