Toilet Tank And Fill-Valve Nut V-Wrench
A 175 mm long, 8 mm thick double-ended V-wrench with serrated 90° jaws. The large end grips plastic fill-valve and flush-valve locknuts and wing nuts from about 40 to 75 mm across. The small end takes tank-bolt wing nuts and supply-line coupling nuts from about 16 to 38 mm. Being plastic, it won't crack porcelain or chew up plastic threads, and you can reach into the tight space under the tank.
Float Arm Clamp-On Coin Ballast Weight
A clamp-on weight for old ballcock and float-arm toilet fill valves that don't shut off fully, so the tank keeps running. It's a 64 x 34 x 30 mm block. The float rod sits in a V-channel that takes any rod from about 5 to 9 mm and is locked in place by a sideways M4 set screw. Four covered slots hold up to 16 US quarters or other coins/washers up to 25 mm across, and two zip ties in perimeter grooves keep the coins and the rod in place.
Toilet Refill Tube Overflow Clip
Replaces the missing factory clip that keeps a toilet fill valve's refill tube from popping off the overflow riser: a sprung jaw straddles the top edge of the overflow tube (accepts 1.5–4 mm wall, locked by an optional M3 self-tapping set screw in the 2.6 mm boss) and a 9.6 mm bore on a 17 mm arm holds the 3/8 in (9.5 mm) refill tube pointed down into the opening with its end above the rim, as anti-siphon code requires. Overall 33 x 30 x 16 mm, prints flat with no supports.
