Is this a Surrey Flange?

[MarkHod]

I am having problems with what appears to be air in my shower pump. Sometimes it is really powerful, others is very poor. It is definitely effected when i turn the temperature up on the boiler. Obviously the thermostat on the tank should cut in and close the valve... but I am not totally sure it is working that well.

However I want to establish if the valve in the picture below is a Surrey Flange, and therefore should alleviate the problem of air in the system.

The pipe with the black lagging goes to the shower pump.

If it is a Surrey Flange is it correctly fitted, as I would expect the non-lagged pipe to go to the shower pump... maybe this is the problem?

Thanks in advance for any assistance.

The non lagged pipe should be the pipe going to your pump. The other should go to a tee. Upwards of that tee, should be the vent and down should be the hot to the rest of your house.

The shower pump should be to top connection as is a warwick flange

But with this type you can still pull some air in

Better off fitting an s flange tbh

Sorry Shaun
It's the bottom for the shower feed.

That's an s flange not a warwick flange

There the samd but on a war the ports are the opposite way round

Ok, so if this is a Warwick Flange would you change it to Surrey or even Essex... assuming this is what is causing air in the system.

Is there anything else I should check first?

Thanks, Mark

Surrey I would install

And other than your cold water tank connector is clean and has water in the tank no shouldn't be
