I chucked the 90deg sink drain, fitted a straight one with 90deg bend further down to clear a drawer, then it ran like whirlpool. Cost about $5 for thedrain and 40c for the 90deg bend.
20' Series Anyone removed their water pressure limiting valves???

I just put a bypass line in with a ball valve so if I have any issues I just open the valve
You can fix the slow draining sink with a check valve placed in the pipe work just after the shower floor drain. Stops an airlock from occuring and works a treat. I posted diagrams in another post on where I put it and the product used if your interested.
I will be looking for the flow restrictor you mentioned as well. Bloody water pressure is very low considering incoming pressure is so high. Would love to have a nice shower at more than the rate of dribbling out.
Thanks

Then I need to increase the size of the water tank
. Maybe an instant hot water is the way to go here?I did my spring it did bugger all for my flow or pressure i want a fitting like @Crusty181 but bunnings dont sell them well none around me anyway if you see one crusty bye me one and send it to me please
Brass valve underneath the van . Not the T shaped valve that is the tempering valve .
I pulled ours apart, took the guts out and put it back, no problem but still low pressure compared to home
If the sink drains slowly and you have a 90 deg plug hole nothing will change until you get rid of the 90 deg sink drain.....cost $9..........as for the twin drain BS, I fitted a 150mm van wide pipe which became a 40lt grey water tank and all my drains flowed into it, no backing up, no twin drains, drains flowed very fast and got a overnight grey water tank too boot, also turn tank off and no dust would blow out of drains...........easily washed out .............http://www.expandasdownunder.com/threads/drovers-14-44-3.4502/ details somewhere in there..........................
I haven't removed the 90deg fitting but I get a nice little whirlpool when emptying the sink now with the check valve mod. The 90 deg fitting shouldn't affect the flow hardly at all. Most flow issues are due to airlocks in the drain lines.
Pretty sure its the 40mm and you can get them here

On mine the 90 deg certainly was slowing things down as the diameter was half the size and a major restriction, with the straight fitting, big hole and it ran away, my drains had been upgraded earlier from the nightmare that was original so no flow problems except from the sink..
You would think Jayco would have ironed all of the issues out of there plumbing. I don't know if its still a problem on newish models but the fixes are so easy I don't understand why they didn't sort them in the first place.
Now @Doug thats the $64 question, I once thought that but then found the faults in my old 2009 Expanda where similar to earlier models and exactly the same as the 2015 models and the dealers express surprise when you front up with the exact same problem that has been happening for 10 yrs...................go figure ??????.................mind you my Coromal has some of the same problems but the plumbing all works with far superior flow.

I like your fix here. Just wondering how much you stretch the spring. I would guess an extra 5mm.
