Apologies if this is in the wrong place before I start! We are in the process of redoing the living in our horsebox as it was very old fashioned! We have got a new sink in the kitchen part that has a microswitch tap. We now need to order another tap for the pull down sink in the washroom and don't know if I need to order a micro switch one or would a normal one be ok? The water onboard is from a tank with a submersible Truma pump and it also has a Whale pressure switch fitted. So do I assume that it is a pressured system? Sorry if I sound dumb, all new to us as although we have an Autotrail it is already nicely done and working and besides I am blonde so it is allowed occasionally I have been told!! Any help would be most appreciated.
