I have a traditional boiler and hot water tank. I have recently added a en-suite to the loft conversion in the attic, so I had a shower pump fitted. The plumber who fitted it wasn't great but it worked OK for a while. When we came back from holiday, it wouldn't work and there was air in the pipework. So I checked the installation instructions, and the plumber hadn't fitted a gravity loop. So I fitted a gravity loop, and again it worked for a bit. However we are obviously getting air from the tank into the pump.
A further check into the installation reveals that it he has just fitted the take off from the tank straight into the top of the tank, without installing an S flange.
So, how do I go about adjusting this pipework to include an S flange? The pipe in the centre of the tank, goes to a T, to the right and down is the gravity feed for the hot water outlets on the ground and first floor. The other side of the T goes up into the attic as a vent / overflow back into the header tank. The shower is connected to the pipe on the right hand side.
The shower flange has a T, one vertical and one horizontal. The feed for the shower comes out the side, and will connect to the gravity loop, but what do I do with the vent? Can I T that into the existing vent?

Thanks, I don't think I'll be able to fit another outlet lower down the tank (the airing cupboard is built tight around the tank). I think I have two options;
1. Take the pipework off the current shower outlet, fit a blanking plug, then fit a s flange to the central outlet, taking a feed off the side for the shower, then run a section up to another T, alter the supply pipework to connect to this side of the T and then adjust the vent pipework to connect into the top of the T.
2. Take the pipework off the current shower outlet, fit an s flange to the tank at that point. Then connect the shower to the side of the flange, and all I have to alter is the vent pipework, connecting the new vertical outlet to the bottom of the vent pipe via a T in that.

Arrrgghhhh! I ordered and picked up one of these;

However, both outlets on my tank are 22mm, and the flange has a 1" BSP thread on the bottom of it. I've been round B&Q, Screwfix and Toolstation and can't find an adaptor that will work.
Does anyone know where I can get an adaptor that will screw onto a 22mm thread and have a 1" BSP thread on other end?

Arrrrgghhhhh. Another week goes by, another hangover on a Sunday, and still I can't get this sorted.
Turns out the other connection to the tank is a 3/4" outlet. So the 1" pump thing won't connect. Can't use a 3/4" to 1" adaptor as then the dip tube won't fit through.
Looks like I'm going to have to order a 3/4" flange instead. But that won't be in until tomorrow, so I've got to put it all back together, again.
