Freeze Protection Valve Kit (Two Valves) for interconnecting Water Lines. Valve kit shall be utilized to provide power outage freeze protection for the GS4 or GS5 Heat Pump unit(s) installed at the home or building. 

One valve is installed on Cold Water line & one valve is installed on Hot Water line. When the water temperature in the 1/2" Supply/Return piping to the GS4 or GS5 Heat Pump falls below 34°F the valve opens to prevent the water from freezing. As the water temperature increases the valve will begin to close until it is fully closed when the water temperature is 39°F.

Kit consists of 2 Valves, one valve will be installed on the 1/2" Cold Water Inlet piping & one valve on the 1/2" Hot Water Supply piping to and from the GS4 or GS5 Heat Pump and the Storage Tank or Piping Manifold. 

Two lead free Tees (3/4" x 3/4" x 3/4") are supplied together with the 2 Valves. Each Tee shall have a 3/4" Threaded connection to install the FPV Valve to. The 2 x 3/4" horizontal threaded connections shall allow the Tee to be connected to the Copper or PEX Cold & Hot Water Piping to the Heat Pump by using field supplied adaptors to reduce the 3/4" Tee to accept the 1/2" Copper or PEX piping used for the Cold & Hot Piping to the GS4 or GS5 Heat Pump.

The SMTW valves should be installed so that they are both in a vertical down position to the piping or upwards up to a maximum diagonal angle of 45° to the Cold and Hot Water piping to the GS4 or GS5 Heat Pump Care shall be taken to ensure drained water from the valve shall not cause a slip/fall hazard.

Didn't even last an hour!
Color: Orange & Blue, Color: Orange & Blue
I had high hopes for these toys as the description sounded like they might be not easily destructible. Well, I was dissapointed again. Our shih-poo (half shih-tzu/ half minature poodle) had one of the toys apart in an hour. See photo.

Stuffed with Plastic
Color: Orange & Blue
So these are super cute and they have crinkle sounds and a squeaker, but these would not be suitable for chewers. The have plastic stuffing in the legs and my dog almost choked on it...so I just have to tell you that these may be ok for smaller dogs but mine is 30 pounds and he ripped through it and started eating the plastic crinkle stuffing.

Awesome entertainment
This is wonderful and entertaining for both you and your dogs. Both mine used the same one as puppies a year apart and still play with it. Great for mentally and physically as it tires them out.

Great Interactive feeding toy
Style: Modern
Works amazing to keep my French Bulldog moving thinking while he eats. It’s been really durable and keeps him engaged while snacking or eating. It’s the perfect size to store a scoop of food in for him.

Entertaining dog toy
Style: Modern, Style: Modern
Overall a good toy. 2 labs enjoy these when filled with some goodies. They have also chewed on them when empty. With them chewing on them, it makes it very uncomfortable to open due to the plastic shards. I will say they become very annoying toys when the dogs try to bounce them on a hard surface this is a carpet toy in my opinion. It’s been good as a slow feeder or just to have the treats in there, keeps them entertained for a few.
