We have a whale 921 water pump on our caravan which doesn't turn itself off, when you run the hot water it runs smoothly, but when you run the cold the water it doesn't flow smoothly. It is on a 1992 Fleetwood Colchester. Can anyone help with this?
the only other thing that it might be is that air is getting in the line or it has and airblock i would try leaving all the cold taps on and see if you can flush it out hope this will sort it out

We have tried the presssure valve but that didn't stop it. Is there anything else that we should try? Thanks
If adjusting the pressure switch does not stop the water it sounds as if it is not working properly and needs stripping and rebuilding - whale sell a kit for this.
The cold water spluttering as it comes out will more than likely be cured by fitting a whale damper right after the pressure switch, the reason the hot water is smooth is because the hot water tank acts as a damper.
