We work directly with your adjuster through our 4 partner networks, scope any drain repair and the valve install as one job, and produce the itemized invoice, drain permit number and backflow test certificate underwriters ask for.

We're partnered with 4 insurance adjuster networks that handle sewer backup claims across the GTA, so many adjusters already know our paperwork. With your permission, we speak to your adjuster directly, share site photos and the camera scope, and agree the scope before work begins. That avoids the back-and-forth where a homeowner relays technical questions they can't answer. If the restoration company is still drying the basement, we time our visit around their equipment. You stay in the loop on every email. The aim is simple: get the valve the insurer asked for installed properly, without delaying your claim or your renewal. ### Documentation and Invoicing Documentation and invoicing are what underwriters actually look at. Your package includes an itemized invoice that separates labour and materials, the City of Toronto drain permit number, the inspection result, a backflow test certificate with the valve make and model, and dated photos of the install before and after backfill. Where drain repair was part of the job, it's itemized on its own line so the adjuster can see what relates to the claim and what's new protection. This is the same paperwork the City subsidy requires, so one set of documents serves both. Everything is sent as a single file, ready to forward to your broker or insurer as underwriting proof. ### Combined Repair and Install Scope A combined repair and install scope saves you a second floor cut. After a sewer backup, the camera often shows a cracked clay joint, a collapsed section of cast iron or a sagging lateral that contributed to the flood. Fixing that and installing the valve in the same pit, on the same visit, is cheaper and cleaner than two separate jobs. We sequence the work with your cleanup crew so the floor is cut once, the drain is repaired, the valve goes in, and the pit is closed after the backflow test. The adjuster sees one scope with clear line items. You get a basement that's protected before the restoration crew finishes the walls. ### Future Premium Impact Future premium impact is the question everyone asks, and the honest answer is that your insurer decides. A properly installed and tested backwater valve is often what makes renewal possible after a sewer backup claim, and some insurers recognize it when pricing sewer backup endorsements. We don't promise discount amounts, because we can't control them. What we can do is give your insurer clear proof: the permit, the inspection, the backflow test certificate and photos. An annual inspection report keeps that proof current. Several customers have told us their premium stayed flat after the install, but every policy is different, so ask your broker what they need to see. ## 5 Steps From Sewer Backup Claim to Insurer-Approved Valve 1. **Call your insurer, then call us.** Report the sewer backup claim and ask what your insurer needs before renewal. Then book the free assessment. 2. **We scope the job with your adjuster.** Camera scope, photos and a written scope, agreed with the adjuster before work starts. 3. **We pull the permit.** A City of Toronto drain permit is filed so the work is legal and inspectable. 4. **We repair, install and test.** Any damaged drain is fixed, the valve goes in, and a backflow test certificate is issued. The City inspector signs off. 5. **You send one file.** The itemized invoice, permit, inspection and test certificate go to your insurer as underwriting proof. We file the City subsidy with the same documents. Ontario home insurance policies vary a lot on sewer backup coverage, so step one matters. Our inspection and testing [/backwater-valve-inspection-testing/ →](/backwater-valve-inspection-testing/) service keeps the proof current every year after. ## Will Insurance Pay for the Valve? In our opinion, plan as if it won’t. Most insurers treat a backwater valve as flood mitigation, an upgrade you make to protect the home going forward, rather than part of repairing the damage. What they often do cover is the water damage restoration and, depending on your policy, the drain repair that caused the backup. That’s why the City of Toronto rebate [/toronto-backwater-valve-rebate-application/ →](/toronto-backwater-valve-rebate-application/) matters so much after a claim. It returns up to $1,250 on the valve regardless of what your insurer pays, and up to $1,750 if a sump pump goes in too. If water is still coming in, start with emergency backwater valve repair [/emergency-backwater-valve-repair/ →](/emergency-backwater-valve-repair/) and we’ll plan the permanent install from there.

Step 1 ### In-Home Drain Assessment and Camera Scope We inspect the main drain, find where the sewer lateral leaves the house, check slope, and confirm whether the pipe is clay, cast iron or PVC. We also confirm your subsidy eligibility. The visit and camera scope are free. 2. Step 2 ### City of Toronto Drain Permit We apply to Toronto Building for the drain permit on your behalf before any concrete is cut. No permit means no subsidy, so we never skip this step. 3. Step 3 ### Interior Pit Excavation or Exterior Dig Dust-shrouded saw cut inside, or a shored excavation at the property line outside. The valve is set on 3/4-inch clear stone bedding with cleanout access. Some installers skip the backflow test, which voids both the warranty and the subsidy. We test every valve under load. 4. Step 4 ### Valve Installation, Backflow Test and Mitchell Harrington Quality Review We backflow-test the new valve, record the results and photos, and founder Mitchell Harrington reviews the test documentation and CSA B64.10 compliance before the pit is closed. 5. Step 5 ### City Inspection and Rebate Submission The City inspector signs off, then we file the Basement Flooding Protection Subsidy paperwork. The cheque typically arrives 6-8 weeks after submission. ## Want a written price for insurance claim install before you commit? The assessment and camera scope are free.
