Overview
Australian Valve Group (AVG) PTR25-700-LF 25mm (1") 700kPa PTR Pressure and Temperature Relief Valve (also known as TPR valve) is Australian Watermark approved and intended for commercial hot water service applications, with a high kilowatt rating of 132kW.
Pressure and temperature relief valves, known PTR valves are critical mechanical safety devices for all hot water services. The temperature sensing probe monitors the hot water service's temperatures. AVG PTR valve temperature probe is covered in a Teflon wrap to prevent any calcification build up overtime and to ensure long term accuracy. Inside the AVG PTR valve body, there is a piston mechanism that opens according to the pressure inside the water tank.
During the operation of the hot water services, the volume of the water will expand during heating cycles, as cold water heats up. This increased pressure can be dangerous if not regulated. The PTR valve regulates the pressure slowly dripping the water out of the tank in a controlled manner, usually via a discharge pipe into a drain or ground. Therefore, when the slow dripping is observed, it is just a perfectly normal PTR valve operation.
When there is a malfunction with the heating component or the thermostat in a hot water service, an uncontrolled heating can be extremely dangerous and explosions can occur catastrophically. PTR valve can detect this when the temperature and pressure exceed 99 deg or its preset pressure ratings. In this case, PTR valve will fully open and dump hundreds of liters of water to relieve the water heater tanks. The Kilowatt rating of the PTR valve refers to the rate that the PTR valve can dissipate this energy and this is regulated by Watermark and plumbing codes in Australia.
When a high kilowatt PTR valve rating is required in a commercial installation, a smaller sized 15mm or 20mm PTR valve must not be used as a cost cutting method for safety reasons.

Size: H11+9005
I’m really happy with these lights! They were easy to set up, work perfectly, and give off a beautiful glow. The brightness is just right for creating a cozy and relaxing atmosphere without being too harsh. The quality feels great for the price, and they instantly made my space look more modern and inviting.
I also appreciated how well they were packaged and how quickly they arrived. Definitely worth the purchase, and I would absolutely buy them again. Highly recommend to anyone looking for stylish and reliable lights!

Termitor H11 are so worth it
Size: H11+9005
LED Lights are as described. They fit perfect in the low beams and high beam spots. LEDs are super bright and work great at night! Soo much better than the old fluorescent bulbs that came with my rig.

Bright light
Size: 9004/HB1, Size: 9004/HB1
Keeping track of longevity. Had these bulbs for a month and will try and update if they fail. Unfortunately a while ago I hit a cow, seemed to just pop up out of nowhere, the truck was rebuilt and I wanted more/better road lighting. I am using these in a Mack truck for work so they are getting used. I run at least 10 hours a day, 5+ days a week and have at least 11k miles on them since installed. Install is just like a standard bulb no special steps needed. Produce a lot of light and good patterns on high and low beam. So far I really have only had one issue with the bulbs and that is the daylight running light/DRL operation, they don't work I believe the Mack drops the voltage to slightly dim the lights when running in DRL operation and this causes the bulbs to just intermittently flash so I just run with them on all the time. This I don't believe is the bulbs fault and is more an analog vs digital issue. Therefore I'm testing the longevity of the bulbs if my truck is running they are on. Will see how they do as the days get hotter as they are in a small sealed space.

Wow bright!
Size: H11+9005, Size: H11+9005
I have used Fahren LED headlights in two of my other vehicles so I had a baseline of what to expect, but these upgraded ones are even brighter than the ones in my other two cars. I love this brand because they are plug and Play so I have not experienced any compatibility issues. These feel high quality as I have expected due to past experience with this brand. I much prefer the bright white color of LED versus the yellowish Amber of halogens. I have been using this brand for several years now so I expect a good lifespan from this as I have experienced from other bulbs from this manufacturer. As far as value goes, the increase in visibility installing these is worth every penny and then some.

Good light, but blinding
Size: H7
The light itself is good and bright and fits well, but I don't know if I installed it wrong, but the driver's side is very blinding, and I feel bad for other drivers and can't do anything about it.
