Genuinely happy with this 15mm pressure and temperature relief valve...
Bought the rmc 15mm pressure and temperature relief valve - 1400kpa - durable safety control after comparing a few options. Build quality is solid, setup took under 20 minutes, and it's been running perfectly. Fast dispatch from Sydney — arrived in 14 days. Would recommend.

Good 15mm pressure and temperature relief valve... — minor packaging issue
The 15mm pressure and temperature relief valve... itself is great. Packaging had a small dent on arrival but the item inside was fine. Took off one star for the box, not the product. Would still buy again.
Still curious
