Fitting drainage tubes with holes in tightly together would slow down the swooshing of water in the tank a lot as each tube would minimise the mass amount of movement into many individual compartments .

Professional fit every time esp if you want a diesel hot system. Get it fitted into a brand new van if you plan on window cleaning for many years to come.

Nothing worse than messing about every few years switching systems from van to van.

I've had this van 16 years Daz but as I'm scaling down to doing less as I'm now only part time so for a start I don't need a 500 litre system a 350 will be fine I also want a nicer more up to date van etc which I'm hoping when I retire fully in around 3 years time I'll be able to sell for a decent price.

I would just keep your van another 3 years. My van is 20 years old, had it from new.

Unless there is something seriously wrong with your van it should last 3 more years of part time work

Installed a new Wydale 500 litre flat tank and the water movement is terrible compared to my previous Enduramaxx 500 litre upright tank.
Has anyone used perforated drainage pipe or baffle balls in their tank to reduce water sloshing and how much of a difference does it make?

Mine is coming up to 14 years in March. I want it and the (DiY) system to see me out over the next 3 years.
