Sloping oil tank and mystery pipe

starstreamer8

Just wondering is the slope on the oil tank in the picture below a problem? It slopes away from the oil outlet so the tank will seem to be empty earlier than it is but are there any other implications?

Also, could someone tell me what the small white plastic pipe pictured below is? It comes from the pipe that supplies the kitchen cold tap (directly from the mains).

Thanks for any insight.

You didnt include pic of oil tank but generally tanks slope towards the rear so any dirt would settle to the rear. This is supposed to stop the dirt making its way down the pipe an blocking a filter.
Regarding the white pipe its a water supply for something. Do you have an RO filtration system with a drinking tap or an fridge freezer with an ice maker perhaps

As Shane said slope away from outlet isnt unusual to prevent water or dirt reaching the outlet. The tank does not meet current regulations particularly the base, maybe a few more pictures or get someone to have a look at it.

The small white pipe is zero supply for a small filter unit or for an ice making fridge as above

Fuel will always have impurities im it. In a car, the vehicle is constantly moving, so these impurities disperse with the fuel.

As a home heat oil tank is fixed, the impurities will settle and build up over the years - some tanks can be there for 40+ years.

A gentle slope away from the outlet will ensure these particles don't get into your heating system.

The oil "used" for the slope would be about 10-15litres - about €6-€10.

Don't be tempted to lift the rear of the tank if you run low on fuel, you will wash all the crud and dirt into your system which can damage your boiler.

Even though a lot of people use it as a "reserve" it can be very costly often resulting in seized pumps

Modern plastic tanks shouldn't and don't need to be sloped. They don't suffer from condensation in the same way that steel tanks do. The outlet is further from the bottom than it used to be on steel tanks.
Manufacturers have said that not fitting plastic tanks level and according to instructions can damage the tank's structure.

That tank looks like it was just put up in place of a steel tank, without any reference to instructions.

That's great info, thanks very much for your responses.
The zero water supply must have been for some appliance that used to be in the kitchen but it's not being used now.
