Why won’t this tell me my chance of a water leak?

Because HyreRestore holds no data on it for a house like yours. Published figures are population averages that say nothing about your plumbing, age or occupancy. Solving for the threshold gives a number you can check against your own house.

Why is a prevented loss worth my deductible and not the repair bill?

On a covered claim the insurer pays above the deductible, so that is what you avoid. If the loss is under the deductible, excluded, or you would not claim, you pay all of it, and the device is worth more than the deductible.

Does a leak detector protect against flooding?

No. These devices watch water inside your plumbing. Water from outside is flood, which the specimen HO-3 excludes and a separate flood policy covers. The flood risk lookup shows NFIP claims and flood cover by state.

What is the difference between a leak sensor and a shutoff valve?

A sensor alerts you; a shutoff valve closes the water supply itself. The difference matters when nobody is home, which is when a leak runs longest. They are different products at different prices.

Will my insurer give me a discount for a leak detector?

Ask your insurer before you buy and get the figure in writing. Enter 0 if you do not have one: the calculator still works, and the break-even simply rests on the losses it prevents.

What should I enter for device life?

The life or warranty period the manufacturer states for the model you are pricing. A shorter life raises the break-even frequency, because the same cost is spread over fewer years.

Does HyreRestore sell or recommend leak detectors?

No. It sells no devices, takes no referral fees and names no brand. The calculator is arithmetic on figures you type, so it cannot be tuned to favor a product.

Is a leak detector worth it?

Type the device price, fitting, any insurer discount, your deductible and the device life. The result is a break-even frequency, not a forecast of your odds.

Break-even = life ÷ (net cost ÷ loss saved) the formula this calculator runs Net cost is device plus fitting minus the insurer discount over its life. Loss saved is your deductible if you would claim, or the whole loss if you would not. Every figure is yours; HyreRestore supplies none.

A leak detector or automatic shutoff valve is worth it if it would prevent one water loss more often than its break-even frequency. A prevented loss saves you your HO-3 deductible on a covered claim, or the whole repair bill if the cause is excluded or you would not claim.

HyreRestore holds no loss-frequency data, so the calculator gives the threshold and you judge your own house.

No odds are estimated: this gives the threshold and you judge your own house. Not insurance advice.

No odds, just the threshold

A sales page needs a probability nobody has for your house. This calculator works from the other end.

The usual pitch. An industry-wide claim rate times an industry-wide average loss, presented as your expected saving. Both are averages over a population, and neither describes one house with its own plumbing, age and occupancy.

What this does instead. HyreRestore holds no water-loss frequency data and will not invent it. Given what the device costs, what your insurer discounts for it, and what a loss costs you, the calculator works out how often it has to prevent one to pay off.

What a prevented loss is worth to you. If you would claim, your deductible: the insurer pays above it on a covered loss. If the loss is under your deductible, or you would not claim, or the cause is excluded, you pay all of it, and the device is worth more.

What the threshold looks like on example numbers

Arithmetic on example inputs, not prices. Each row was run through the calculator on this page; type your own quote to get yours.

Example	Worth of one prevented loss	Device life	Break-even
Net cost $100	$2,500	10 years	one loss every 250 years
Net cost $600	$2,500	10 years	one loss every 41.7 years
Net cost $2,000	$2,500	10 years	one loss every 12.5 years
Net cost $100	$1,000	10 years	one loss every 100 years
Net cost $100	$5,000	10 years	one loss every 500 years
Net cost $6,000	$500	10 years	1.2 losses a year

Net cost is the device plus fitting, minus the insurer discount over its life. The last row shows the case where the arithmetic does not work: a high net cost against a low deductible.

What to settle before buying one

The arithmetic is the easy part. These decide whether the device does anything for the loss you are worried about.

Does it alert, or does it shut the water off?
A sensor that texts you does little if you are on a plane. An automatic shutoff valve acts without you. They are different products at different prices.
Where does it sit in the plumbing?
A point sensor under a dishwasher covers the dishwasher. A valve on the main covers everything downstream of it. Neither stops water coming in from outside.
Will your insurer discount it?
Ask before you buy, get the figure in writing, and type that number here. Some insurers set conditions such as a device type or monitoring.
What happens if it fails or trips by mistake?
A valve that closes while you are away has its own effects: a boiler or sprinkler system with no water. Ask how it fails and how you override it.
Who fits it?
A valve on the main is plumbing work. Ask your building department whether it needs a permit, and your insurer whether self-fitting affects the discount.
Is the loss you fear the one it prevents?
Supply lines, water heaters and appliance hoses, yes. Roof leaks, groundwater, sewer backup and flood, no: the is it covered checker shows how the specimen HO-3 treats each of those.
What is your deductible in dollars?
A percentage deductible has to be turned into dollars first. The deductible calculator does that.

What this calculator leaves out

Disruption. Weeks out of the house, belongings in storage and the time a claim takes are real costs, and none appear here. The threshold is a floor, not the whole account.

Your odds. HyreRestore holds no data on how often a house like yours has a water loss, and does not guess.

A recommendation. HyreRestore sells no devices, takes no referral fees and names no brand. It is arithmetic on your figures, and not insurance advice.
