G'day all.

I have a Trailking 7 water pump in my motor caravan and the taps continually deliver air as well as water, even when the pump should have been well and truly primed. I would expect some air after not using the system for a while and newly filling the onboard tank.........but not forever. Anyone with previous experience of this annoying spectacular please and any advice? Thank you!

Hi there

Interested to see your responses on this as I have exactly the same problem with mine. I tend to suspect a ruptured diaphragm in the pump but I dont want to replace unnecessarily.

Regards

Thanks John. I will look at that valve. I have emailed SHURFLO to see if they can advise also and will post any reply received. Thier customer service appears to be in Belgium. Let's hope that they can produce a solution as well as those rediculously lovely chocolates.

Hi Keith

Not sure how you have gone on with your pump issues but mine now seems to be OK. After sticking my head in a bed box whilst getting someone else to operate the taps I noticed a very small drip from where the two halves of the pump join. Working on the theory that where water can come out air can get in I removed the pump and undid the philips screws that hold the two sections together. Here there was a seal which had lime and calcium deposits stuck to it. I removed the seal thorougly cleaned in and then refitted. A smear of an appropriate gasket seal on the outer edge of the rubber seal (so as not to contact the fresh water side at all) was applied before reassembling the pump. On refitting no air bubbles in the pipes and a vastly improved water flow.

Thanks for the data sheets

John
