Water leak, Peugeot symphony.

Just had a minor problem with a shower room water leak.
I noticed that the water pump was starting up on its own occasionally just for a couple of seconds, indicating a drop in pressure and a small leak.I eventually tracked it down to the bathroom sink tap, I removed the rear plywood panel and found a slight dribble of water from the plastic fitting on the hot tap, I pushed the fitting back into the back of the tap and it 'clicked' back into place and the leak stopped. I don't know if this has happened to anyone else but it seems like a problem that's waiting to happen,there is a fair bit of weight with all the pipes and fittings just hanging on to push fit connectors, i suppose a bumpy road or pothole may have jolted it loose,can't think of any other explanation, anyway I thought it might be an idea to support the weight of the pipes using plastic ties connected to the sink drain which seems pretty substantial.
Hopefully problem solved.

I know what you mean, I thought of giving mine some support when I changed the taps a while ago. But in truth, I have never had that problem in over 10 years of ownership.
