WHy in the worls would you stock an item like this, and not stock the repair kits. Seems logical.

Asked by wyoavsfan July 8, 2014

It's honestly cheaper to buy a brand new backflow then it is to buy the repair kits. Lastly if your backflow is only lasting you 1-2 years you're not having it winterized properly or you're waiting to late in the year water freezes at 32 degrees they are plastic parts it doesn't take much of a freeze for those to crack and break

Best to fit whole unit as you know no small bits of scrap or worn sections included. Also easy to fit as one new unit, only had to buy one quick fit 'Shark' straight to connector to complete the job, NO SOLDERING needed, a big bonus.

Would a back flow preventer be on a 2nd floor bathroom tub

Asked by Gerry September 30, 2017

Answers

Not generally. This item is used to keep a water(supply) system separated from a water use area. There is now a code requirement that toilet flush valves a type of vacuum breaker system in the toilet tank. Sink, bath and shower supplies are not connected to the water-use areas, so there is no chance that water can be siphoned back into the public water system. This type breaker is used for example, on sprinkler systems, where the water entering from the domestic water supply can run to a sprinkler head where there is a chance that the head could be in a puddle of standing water that could be drawn back into the domestic supply, if there were a break in the supply line. Also, these are used around lower lying areas that are subject to flooding or open water. Marinas have them to keep boater's water hoses that are routinely kept connected to the potable water system from drawing water out of a bilge or from the sea into the public drinking water system. You may be required to have one around a swimming pool where the water supply is connected to the pool.

Isn’t a it a Watts?

How long would it take for this item to be delivered to the UK and is it ok to use on potable water supply ?

Have no idea about your first question, spend enough and you can probably get it over-nighted. Europe must have them. These are designed to keep the potable water supply separate from other water systems or supplies; such as pool water, boating facilities, or irrigation systems.

Is this a replacement for, or can this be used instead of the Watts 800M4-FR?

Asked by Joe May 24, 2020
1
Answer

As far as I can tell, this is an 800M4-FR. There are different sizes, so as long as you need a one inch assembly it should work. The different types of this assembly use differing handles on the small valves. There are stainless and quick connect fittings. But, generally, this is an 800M4-FR.

Beware
I got 1 season out of this unit before it cracked and needed to get another. Bought one last week and swapped out the broken unit. Turned it on and water wouldnt stop gushing out the top, so I watched a Youtube video to see what I was doing wrong. Turned out my brand new factory sealed unit was missing multipe pieces inside the bonnet. I called the company and they said they werent surpried and to bring it back. Would have been more professional of them to appologize and offer to send me the missing pieces.

Actual valve was a Zurn. UPC and all info was correct so the item is wrong in the H.D. system. Zurn valve was the same size and type and works great, but they typically retail for 10-20% less than Watts... It would be great if price reflected that.
