How much does it cost to replace pool closing plugs and gizzmos each year in Ottawa?

Replacement winter plugs typically cost $3 to $8 each, and gizzmos (threaded skimmer winterizing tubes) run $8 to $15 each, making the total annual replacement cost for a standard Ottawa pool roughly $20 to $60 depending on how many fittings your pool has and whether any components survived the previous winter in reusable condition.

Winter plugs — also called expansion plugs or freeze plugs — are rubber plugs with a wingnut-and-plate mechanism that you insert into return jets, suction lines, and other plumbing penetrations at the pool wall. Tightening the wingnut compresses the rubber, creating a watertight seal that prevents water from entering the plumbing lines after they have been blown out and antifreeze-treated. A typical Ottawa inground pool has 2 to 4 return jets, 1 to 2 suction lines, and a main drain, requiring 4 to 7 plugs in various sizes. The most common sizes are #8 (for 1.5-inch lines), #10 (for 2-inch lines), and #11 (for larger returns), with prices ranging from $3 for small standard plugs to $8 for heavy-duty or oversized models.

Gizzmos serve a different but equally critical function. These hollow threaded tubes screw into the skimmer basket housing and absorb the expansion force of ice forming inside the skimmer body. Without a gizzmo, water that collects in the skimmer — from rain, snowmelt, or condensation — freezes and expands against the rigid plastic skimmer walls, cracking or shattering them. A cracked skimmer body is a $300 to $800 repair that requires cutting into the pool deck, so the $8 to $15 cost of a gizzmo per skimmer is one of the best-value investments in pool winterization. Most Ottawa residential pools have 1 to 2 skimmers, so you need 1 to 2 gizzmos.

Whether you need to replace these items every year depends on how well they survived the Ottawa winter. Rubber plugs degrade over time — the rubber hardens, cracks, and loses its ability to compress and seal properly. After one Ottawa winter of freeze-thaw cycling, some plugs remain perfectly serviceable while others show visible cracking or permanent compression. Inspect each plug carefully at spring opening: if the rubber feels stiff, shows surface cracking, or does not expand back to its original diameter after removing the wingnut compression, replace it. Most pool professionals recommend replacing all plugs every 2 to 3 years as a precaution, with spot replacement of any obviously damaged plugs annually.

Gizzmos are more durable than plugs but still have a finite lifespan. The hollow plastic tube is designed to collapse inward slightly under ice pressure rather than transferring that force to the skimmer body. After absorbing expansion forces through several Ottawa winters, the plastic can develop stress fractures or deform permanently, reducing its protective ability. A visual inspection at spring opening — looking for cracks, splits, or sections that have crushed inward significantly — tells you whether your gizzmo has another season in it. Most gizzmos last 3 to 5 Ottawa winters before replacement is advisable.

Where to buy replacements in Ottawa without overpaying requires a bit of shopping. Pool specialty retailers stock the full range of plug sizes and gizzmo types year-round, with prices at standard retail. Online retailers like Amazon and Pool Supplies Canada offer lower prices but factor in shipping time — order by early September to ensure delivery before your closing date. Some Ottawa pool closing services include new plugs and gizzmos in their service package at no extra charge, while others bill them as separate line items at a markup. Ask explicitly when booking your closing service whether replacement consumables are included in the quoted price.

A few specialty winterizing products beyond basic plugs and gizzmos are worth considering for Ottawa pools. Skimmer cover plates — rigid foam or plastic plates that sit over the skimmer opening beneath the winter cover — provide an additional layer of ice protection for $15 to $30 each. Aquador skimmer closures create a watertight seal over the entire skimmer face, preventing any water from entering the skimmer body at all, for $35 to $60 each. For pools with wall-step units or built-in spas, specialty plugs and ice compensators designed for these larger openings may cost $15 to $40 each.

Smart Ottawa pool owners keep a small winterizing kit stocked with spare plugs, an extra gizzmo, and thread-seal tape. Total cost for a spare kit: $30 to $50. Having these on hand means your closing technician — or you, if you handle your own closing — never delays the winterization because of a missing or damaged plug. Store the kit indoors over summer so the rubber plugs stay supple and the plastic gizzmos do not become brittle from UV exposure.
