Good morning. I keep getting a tiny shock from my shower valve. Not a serious bolt, but it needs sorting. It feels like a tiny static shock but happens every time I touch the metal valve or head. I don’t wear nylon frocks ? and I have wooden floors. If it was static I would assume that once discharged that would be it until it builds up again. I’ve had a few AC shocks and it’s not that. I’m on a shoreline and have an immersion heater. The first time it happened I thought I had imagined it, it’s that small but unnerving. My other half said she got a shock from the kitchen tap. I haven’t yet. The plumbing is all plastic. I’m thinking there could be some sort of continuity through the water and have an issue with the immersion element. I have recently replaced my charger and inverter with like for like Victron stuff and haven’t touched anything else. The problem started before that anyway. As I said, it’s a tiny shock. I’m also concerned about the possibility of galvanic corrosion. I have a Victron galvanic isolator installed as per manual. Any help would be appreciated. Thanks.
