One frowned immediately and gave me the death stare while the others also started to walk away. I then asked what was wrong and humbly
asked, thats when we started really talking and learning.
Bro 2bfree has pointed out the reserve tank issue which is pretty true as you bypass the tank, some will add additional pumping to service the tank as well but it will start to get messy.

What sort of plastics are used to make a poly water tank?
Water tanks used for storage are made from a wide variety of poly chemicals. Poly is the abbreviation for Polyethylene (PE), a light, chemically- resistant thermopoly, is the most commonly used poly resin. Polyethylene resins include linear high density (HDLPE), cross-linked high density (XLPE) and linear low density (LLDPE) resins. Polypropylene (PP) is a light, durable thermopoly that is denser, stiffer and stronger than polyethylene and has a high melting point. Polyvinyl chloride (PVC) is a durable, transparent thermopoly that is resistant to non-essential oils but cannot be exposed to some solvents. Polyvinylidene fluoride (PVDF) is a durable thermopoly that has high resistance to chemicals and abrasion.
What is the advantage of a poly tank compared to say steel tanks?
Poly tanks have several advantages over the traditional steel tanks. Their seamless construction provides them with greater impact strength and superior resistance to rust, corrosion and fuel additives. These virtually indestructible tanks have a longer lifespan than steel tanks, which can rust through and leak. Poly water tanks are fast and easily produced. Poly water tanks also cost less overall than steel tanks.
