I installed a salvaged Scandvik shower mixer, part #10466 in the hot hole in the bathroom counter when I replaced the taps. It was fine until I winterized the boat last fall and wondered why there was pink on the counter and dripping out of the facet.
I opened the cartridge and found that there is a o-ring that sits atop the upper ceramic disc that appeared to have been pinched. How this happened I don’t know. Perhaps it swelled from the alcohol in the antifreeze?
After searching the internet and finding the model #, then contacting Scandvik I received a parts diagram and a quote for $30 USD plus shipping for a new cartridge. 10466_Scandvik_shower_mixer_parts. The actual cartridge says “made in Italy”.
What I really needed is a twenty four cent o-ring, not a fifty dollar cartridge. After a few visits to plumbing stores, Canadian, Tire and Home Depot I realized that I need an o-ring specialist. My local supplier was happy to sell me the correct silicone ring, but they have a $25 min order.
I found oringsandmore.com online and they sent me 25 silicone o-rings for $6 USD and $4.50 shipping. That’s more like it!
I ordered 18mm inner diameter with a 2mm thickness. The o-ring is a bit large in thickness, but seems to do the trick, I’ll have to see how it fares with water pressure, but I think it is fine. If the o-ring fails I have 24 more replacements to go through before I order the 1.5mm for $5.50.
Happy to report it works like a charm!
