Overview

AW WSP50LF Solar Rated Non Return One Way Check Valve is spring loaded and designed to prevent the high-temperature backflow from the roof collectors present in solar hot water systems. In order to survive this high temperature working environment, the AW check valves are constructed with lead free DR brass body, silicone seals and high temperature rated full brass internals.

During the operation of solar hot water systems in summer, a stagnation condition can be created as the storage water tank reaches its maximum top out temperature usually around 60-70 degrees. In such stagnant conditions, the solar pump will stop water circulation and the solar roof collectors can reach 180°C in flat plate panels and 200+°C in evacuated tubes. This super heated water remains in liquid form due to the pressure in the solar hot water system and pushes down back to the water tank creating the backflow. This back flow can cause damages to the water pumps, flow meter and other components if not prevented. A standard check valve that is not solar rated will melt over time with the usual plastic internal components. A swing type check valve would create excessive flow resistance and poor seal. The AW WSP50LF spring loaded solar rated check valve is perfect in such installations, offering minimal pressure drop during water pump operation and long lasting seal even in continuous high temperature environment.

The AW solar check valves can be installed in either vertical or horizontal orientations and is WaterMark Approved for compliance in Australia. The solar rated check valves can be also used in low temperature rating steam applications.

Prevents me from adjusting the air vent up or down
It's true that it doesn't block the air flow. I had to put it on the left passenger side vent to retain the ability to point the driver's air vents where I want. With it over there, I have to turn my head too far to the right when I'm driving to see my phone, and the passenger can't adjust the vent up or down. Also, phone can't tilt as far left and right as other ones. Good price, unique design, easy to install, feels sturdy, holds iPhone SE fine, and doesn't block my view of the entertainment system.

BETTER THAN A CUP HOLDER
I had a cup-holder mount and it was always falling apart. No matter how it was turned, to unfasten my phone I had to move the spring part of the holder in the same direction that removes the entire clip from the stem of the mount. Of course, I eventually lost the clip. What a bad idea. And, in a 4-Runner, on my cupholder, MAPS sometines got lost and I would have to hold my phone up to the windshield for a minute to get back MAPS back on track. Also not a good Idea. We're not supposed to be handeling a phone and driving so holding my phone up to the windshield is kinda like flagging down a cop. (The 4-Runner has hand-free phone service, as well as some kind of circuitious navigation but it's always lost.) . So, for about $9 on sale, I though I would try one of these LISEN mounts. It works great ! Really. Easy to attach securely but scratchlessly it to my center AC/heat vent and It is infantly moveable. Swing the arm 360 degrees, in and out, phone up or saideways, and tilt the phone to me or the Boss. If I get bored, I can relocate it anywhere along the center vents, or even over to my side vent if I have nothing better to do.. It is sturdy, quiet, easy to clamp in my S21, and release is simplye by pushing the button on the back. Sooo much better that my previous mount, for a third of the price. It might be the best $9 you ever spent. And still worthwhile,if you have to shell out the $18. (But I always try to avoid paying full price for anything). Enjoy !

Usable but average, with only basic build quality and stability.
This in-car phone mount is fairly average overall. It’s easy to install and works for basic navigation needs, but the build quality isn’t particularly impressive. The materials feel a bit ordinary, and stability can be an issue on rough roads, with some looseness over time. It’s usable, but not outstanding.

Best wax ever - not kidding!
We have 2 classic cars we restored and put in shows, along with our regular daily drivers. Some of the cars are darker colors, like grey, blue, or black, and the others are white and a light seafoam green. The problems I've had with other waxes, including other higher end products was streaking, and not being able to remove the swirls. Not so with Black light. This is hands down the best wax I have ever used. The application is simple, and I've done it in shade as well as sun, both with excellent results. Use a microfiber applicator to apply, thin, not thick coats in a circular motion. Then wait - let it set for 15 minutes. Final step - use a clean microfiber cloth to remove. It removes so easy, and leaves no swirl or haze like other waxes. The depth of shine is also noticeable. It makes the paint smooth with a deep shine, no matter the color or if its metallic or not. It just looks great. Bonus - it even smells great! I was so impressed I ordered a few more of their products and we'll be testing those shortly. For years I've bought and tried almost everything at stores and car shows and nothing impressed me. Black Light impresses me so much I'll be using it exclusively from now on. It's really that good.

This stuff goes on easily. You use very little product and it cleans off easily. Leave an AMAZING shine and really makes the black look deep. I am vey happy with this product.
