An Italian-made replacement bladder sized for the Bestank-Solar 19L pressure tank — the standard service item for a 19L tank that's reaching the end of its membrane life but is otherwise in good condition.
When This Bladder Is the Right Part
The 19L bladder is size-specific — won't fit 12L tanks (too large) or 50L tanks (too small). Confirm tank size before ordering:
- 12L tank: 250 mm dia × 370 mm height — different bladder
- 19L tank (this bladder fits): 290 mm dia × 390 mm height — model BHT-19V-S
- 50L tank: 340 mm dia × 700 mm height — different bladder
- 100L tank: 460 mm dia × 990 mm height — different bladder
The model number on the tank label is the definitive identifier. For Bestank-Solar tanks, the model is BHT-[capacity]V-S where capacity is in litres.
Why You Replace Bladders Rather Than Tanks
A pressure tank's metal shell, pre-charge valve, and connection ports typically outlast the rubber bladder by a factor of 2 to 3. When the bladder fails, the rest of the tank is still serviceable. Buying a replacement bladder rather than a complete new tank typically saves 60-70% of cost and reduces installation labour to just the membrane swap.
Italian Membrane Quality
EPDM/BUTYL composite, made in Italy, with the European Union and USA hygienic certifications that establish the membrane as safe for direct drinking-water contact.
The two-material composite addresses the two failure modes of pressure tank bladders:
- EPDM: elasticity and fatigue resistance — handles millions of pressure cycles without splitting
- BUTYL: gas impermeability — keeps the air pre-charge from migrating across into the water side
Cheaper monocomponent bladders typically fail by one or the other within 3-5 years; the Italian composite typically delivers 10-15 years of service.
