16/22mm tap...

At the moment for water changes I just plonk a water pump into the tank and pump out.

I was thinking it would be easier, and nicer for the fish if I put a tap in the hose of my filter, which I could simply attach my long pipe (behave) too and simply let gravity do it's work.

So, what I'm looking for is a tap with 16/22mm connections.

Anyone know where I can get one, or if this is indeed a good idea?

I want something like this, but with a spout to connect my water change pipe.

I was going to do this but instead added a valve to my fill hose to syphon the water. B&Q do lots of valve and bits like this.

I picked up a nice valve and tap which looks perfect for what I want. Will let you know how it goes, and if it is worth it. With some pics of course.

Well, I did this...but ran into a few problems;

1. Using gravity, the flow was just too low for a large water change. It was going to take me hours to change 240L of water.
2. For some reason, the introduction of the tap into the filter inlet caused the top of my Eheim 2080 to leak. Not much, but it was pooling on the floor when left overnight. I'm not sure why this would happen? When the tap was removed, no leaking.

So, I think something like this is good, just not in the way I did it, and if you want a faster change, a water pump is still needed. It was however, extremely hassle free to remove the water and may be something I explore again in the future.

Very odd about the tap. :/

Don't really understand it to be honest why it would make the top of the filter leak...perhaps something to do with the pressure?

Don't know. Hopefully someone can shed some light.

Filter back to normal now though, dry for 48 hours, which is a relief.

Is it because canister filters are pressurised and with introducing a tap you're restricting the flow therefore increasing the pressure within the canister??

Sounds feasible to me :tu:
