Have a look at this garden pressure sprayer for plants:
and the washer or seal in the bottom of the pump tube:
The washer shown is in good condition, but I have a larger sprayer to
eactly the same design (one sprayer is from Aldi, the other from
Wilko) which I stupidly left the whole winter half-full with white
vinegar, and as a result its washer is completely deformed.
But that is the ONLY part that stops the large sprayer from
functioning. I need a new washer, cost estimated at 2 pence!
Has anyone ~any~ idea where I might obtain such a washer?
There is the Matabi 5/ 7 Kima/ Style Repair Kit , and probably similar
kits, but these are more expensive than the sprayer was new.
The washer diameter is approx 21 mm.
By the way, I've called it a washer, but it's really a one-way valve
seal that allows the pump to pressurise the bottle.
