b) Material Durability:

Plastic tanks are light and will not rust. Stainless steel is durable but costs much more. Look for UV-resistant polyethylene for long outdoor life. Translucent tanks help you see the fluid level.

c) Pump Mechanism Types:

Piston pumps generate higher pressure for long reach. Diaphragm pumps handle powders and abrasive solutions better. Battery pumps save you from the physical work. Choose the mechanism that fits your physical ability.

d) Nozzle Versatility:

Adjustable nozzles let you switch spray patterns easily. Fan tips cover large flat areas very quickly. Cone tips work well for individual spot treatments. Brass nozzles last longer than plastic nozzle types.

e) Seal Quality:

Viton seals resist harsh chemicals and resist swelling. Standard O-rings may fail with strong weed killers. Leaks are dangerous, so check seal quality. This is vital for sprayer maintenance and cleaning.
