Why would it pump over, if the headloss between open vent and cold feed is < height of vent loop above F/E tank TWL? Which it must be anyway to avoid over-pumping, however the system is arranged.But I wouldn’t be sure if it would pump over

If the F/E tank and pipework are existing, why go to the expense of changing to an expansion vessel? You would still need to decide where to connect it (ideally between boiler and pump IMO)Technically it is before the pump
And he won't seal it due to him thinking it won't take the pressure

Open vented system must have vent from flow on boiler before any other connection.
Excellent!
An old boy told me the pump will last longer if it is running on the cooler return water, hence the old way of doing it with the pump on the return. Don't bleed the rads with the pump running, though

Seen that happen Shaun quite a few times bud i had the same issue with the Worcester classic system I posted on here couple of months a go pipework was poorly installed cast your mind back I sealed it but as I said the working pressure was set to a bar not much more than a open vent system worcesters dont work on a pressure switch so you can run it on low system head low as 0.5 bar worth considering bud good luck kopNormally no inserts used

That wasn't one of your original options, but that would be OK.ive decided to put the pump on the return and keep the feed and vent to spec if it does pump over will give him the option to leave or seal it
