havn't stripped it down yet as it is only a slight weep which stops when using the heating. i didn't really want to strip it till i had the correct part in hand. there is a large nut just above pump that joins the pump to the heater matrix pipe. nut is approx 30mm across flats.
i have a icon23t combi boiler installed and want to put a decent shower in which would have a nice pressure, can anyone recommend a decent mixer shower that would run well of the said boiler. been looking at mira combiforce 415 any one got any veiws
