We have had luck escape from a flood.

We are camped at our new small property in Rylstone NSW and in the process of converting a two-story shed into a house, which will be an escape from city life when we are not enjoying the life on the road with a Bushtracker
We had been ‘hard at it’ all day & were on our way to town (20 minutes) for a ‘nosh- up’.
I had just had a shower, (we are connected to tank water,) & was getting dressed, when the Flojet pump started running.
This shouldn’t be happening, so I called to Pat to switch it off.

The slider holding the outlet port of the pump had become unlatched allowing the outlet port to come out and discharge water everywhere!
In the few seconds it was running, we had a lot of water to mop-up.
What worries me, if this had happened 5 minutes later, since we are connected to a 20,000 litre rain water tank, while we were away for about two & a half hours, we could have had the van flooded with a couple of thousand litres!!

Has anyone experienced an outlet port coming free? This is a first for us, & should we maybe put a cable tie around the slider to keep it in?

I checked the pressure generated by the pump on a plumbers pressure gauge at 45 psi. The book says the rating of the Flojet is 35 psi, so maybe we need a new pressure switch??

Any advice or suggestions?
