Hi all,
So the next mod I have tackled is the replacement of the clear hoses under the van. In looking at this I was not happy with the high pressure layout. In particular the use of bend radius (and not using elbows) going into the floor penetrations. So I bought some JG connectors and some hose and needed to modify them first. Supprisingly easy to work with and other than one connector which was not pushed in all connections sealed first time.
Then it was onto the original job to replace the clear. I used drinking water hose (white inside with blue stripe) and also added 2 taps per water tank so that I can choose which tank is used for preasure pump and hand pump. For the filler hoses I went for 25mm drinking water hose. After looking at the clear ones I was told to get the right ones (so I did).
If I had the time I must admit that I would rip all of the water hoses out and start from scratch. Although I fixed up the bends etc it is still a mess associated with the positioning of the floor penetrations and overall running of the hoses.
So all went well, until it came time to test the hand pump. This did not go well. When pumping the water up it felt like I was creating a vacuum and that the handle was on a spring. So after many removals and installations and trying the pump in buckets of water in and out of the caravan it came down to an elbow joiner that was blocked. Some of the plastic molding was causing it to block. It went in the bin and a new elbow used and the pump was working.
This then leads to the next problem. The hand pump is leaking at the spout. There are two seals (top and bottom) that allow the spout to rotate, similiar to a mixer tap. Simple get replacement seals. Went to the caravan place (Jayco agent) and guess what I get informed that they do not do spares but I can have a new pump for $75. I think not. Off to the plumbing supplies and although I had the seals and measurements they could not help, unless I provided the make and model. So the next place was CBC bearings and some o-rings. Went home and installed the o-rings and added some food grade grease and it seems to have sealed the spout.
So if anyone knows where you can get the hand pump seals from I would be happy to know, else the o-rings will stay.
Cheers
Steve
