Your techs should be selling propane, not chasing anode readings.
LP Integrity tests, documents, and keeps your buried tanks provably compliant with NFPA 58. You never have to think about it again. We do not sell propane, so the reading is the truth.
One reading. Three kinds of relief.
Whether you run a fleet of buried tanks, own one in your yard, or need a closing to survive an inspection, the job is the same: a defensible, dated record that a tank is protected.
Managed Compliance
Hand us the fleet. We test, document, track every retest date, and give your office a live compliance portal. Out of sight, out of mind.
Tank Health Test
You own the tank, so you own the risk. Get an independent, plain-language pass or fail and a dated report you can hand an insurer or a buyer.
Pre-Sale Certification
The one thing the home inspection does not cover. A closing-ready certificate in 48 hours, so a buried tank never stalls the deal.
Most buried tanks are only checked the day they fail.
A sacrificial anode quietly wears out underground. Nobody sees it. The steel starts to corrode, and the first sign is often a leak. One operator described pulling a failed tank out of the ground: when he lifted it, it was like swiss cheese.
The problem was never understanding the code. It is executing it on schedule, tank after tank, year after year, without a single date slipping.
“I've never heard of a solution to analyzing the condition of the tank. Until it fails.”
Consequence of skipping it is not a fine. There is no published fine schedule. It is a supplier refusing to fill, an insurer denying a claim, and the owner holding the liability.
We close the loop the testing-only crowd leaves open.
Anyone can take a reading and email you a PDF. The value is what happens around it: the repair when it fails, and the calendar that never lets the next test lapse.
- 01
Test
Four-point cathodic reading against a copper-sulfate cell, at the tank.
- 02
Document
A photo-anchored, timestamped certificate you can verify online.
- 03
Repair
Failed anode replaced, dielectric fixed, and the tank brought back to protection.
- 04
Retest
We confirm the fix worked, so the record shows protection restored.
- 05
Auto-schedule
The next test books itself on the code cadence. The date never slips.
Cadence done right: first test 12 to 18 months after install, then intervals not to exceed 36 months. Not a lazy “every 3 years.”
We don't sell propane, so the reading is the truth.
A supplier testing its own tanks
- The company that profits from the fill also grades the tank
- Testing competes with delivery routes for the crew's time
- More than half of marketers don't track the retest intervals at all
- Records live in a filing cabinet, hard to produce for an inspector
Is your buried propane tank protected?
Answer three quick questions. We'll tell you where your tank likely stands and what to do next.
Buried tank self-check
This is guidance, not a substitute for a real cathodic reading. Only a test confirms protection.
1. Do you know the last time your tank's cathodic protection was tested?
2. How old is the buried tank?
3. Has a supplier ever hesitated or refused to fill it?

Buried propane tank testing, answered straight.
The questions people actually ask, answered accurately. If a number is uncertain, we say so.
After a tank is installed, the cathodic protection is first tested within 12 to 18 months. After that, it is tested at intervals not to exceed 36 months, and again after any repair. It is not a flat every-three-years rule, and getting the cadence right is the whole job. LP Integrity books the next test automatically on every pass, so the interval never lapses.
A tank is protected when the structure-to-soil reading is at or more negative than -0.85 volts, measured against a copper/copper-sulfate reference cell. A less negative reading, for example -0.71 volts, fails and means the sacrificial anode is spent and the steel is no longer protected.
Yes. A qualified independent tester can perform the reading and produce the documented record. Because LP Integrity does not sell propane, the reading is not tied to a fuel contract. Many owners and propane companies prefer an independent record precisely because there is no incentive to fudge the number.
A supplier can refuse to fill a buried tank without current, documented cathodic protection, because filling an unprotected tank is a liability and can void insurance. A passing test and a dated certificate clear the block. If it fails, we replace the anode and retest so it can be filled again.
A standard home inspection does not cover the cathodic protection on a buried propane tank, so a buyer, lender, or insurer can raise it late and stall a closing. A pre-sale test with a closing-ready certificate removes that risk. LP Integrity delivers certification within 48 hours, or 24 on a rush.
A failed reading means the sacrificial anode is spent. The fix is usually a new anode bag, sometimes a dielectric fitting, followed by a retest to confirm protection is restored. LP Integrity does both the repair and the retest, and the original test cost is credited toward it.
There is no published fine schedule for cathodic protection on buried propane tanks in New Hampshire, and we will not pretend otherwise. The real consequences are practical: a supplier refusing to fill, an insurer denying a claim, and the owner carrying the liability if the tank fails. That is reason enough to keep it documented.
