Cold feed & expansion configuration on a fully pumped system

The boiler is on the RH side, the flow is from the 28mm compression elbow, the first connection is the 22mm expansion which rises vertically, then is the 15mm cold feed which enters from the underside, next is the pump with its isolating valve, on the LH side is the Honeywell "Y" plan valve and in-between the valve & the pump is the By-Pass which is this case is in 28mm which is far too big
