Review: Best of what the industry has to offer - After living in Belgium for four years it became apparent that in Belgium its not common to have a bidet at home, but I knew that I wanted a built-in bidet for my kids to stop chafing their butts with dry paper. I also wanted to have a well-working, comfortable and maintenance-free solution, so I opted for the Japanese de-facto industry standard: Toto. Sadly enough, Toto does not sell its Washlets in Europe, only complete toilet units, which start from 5k EUR. So I went through the trouble of ordering a washlet from US, got a transformer and a fitting adapter, and all for the comfort of my kid's butts. In total with installing a three-way valve it cost me about 750 EUR. Was it worth it? Absolutely. Am I happy? You bet. The only thing I could wish for is for the seat to have a bigger opening, because since I'm a big person, I cant keep my tool from touching the front wall of the bowl when I use it for no. 2, but for the kids its perfect. For those windering the transformer I used was a Bronson++ TI 500 and the adapter fitting I had to order has the Toto part no. THP3141 Review: If you want to use a filter with your washlet, you need one of these - Just got myself a K300 Toto washlet. Love it. But my house has hard water, and that meant if I didn't want sediment messing with the internals, or gross buildup, I was going to need to run an inline water filter between the source and the washlet. This is the right attachment. You hook up the female end of the water filter to the T-adapter included with your washlet, and then you screw this onto the male end of the water filter. From there, the washlet hose screws onto this adapter. Make sure it's as tight as you can get it by hand or you might see a slight leak. That's it, pretty easy to do. ## Features - 1/2-in Adapter for SW583 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B012OV7JOM | | Best Sellers Rank | #436,807 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #1,075 in Toilet Replacement Parts #2,676 in Toilet & Urinal Parts | | Brand | TOTO | | Brand Name | TOTO | | Color | Brass | | Connector Type | Adapter | | Customer Reviews | 4.6 out of 5 stars 60 Reviews | | Exterior Finish | Brass | | Included Components | Product Only | | Item Dimensions | 1 x 1 x 1 inches | | Item Type Name | Toilets and Bidets | | Item Weight | 0.27 g | | Item dimensions L x W x H | 1 x 1 x 1 inches | | Manufacturer | TOTO | | Manufacturer Part Number | THP3141 | | Manufacturer Warranty Description | 2 Year Manfacturer | | Material | Brass | | Material Type | Brass | | Model Number | 4328736849 | | Number of Packs | 1 | | Number of Pieces | 1 | | Size | 0.5 inches | | Thread Size | 0.5 inch | | Thread Type | NPSM | | UPC | 739268283763 | | Unit Count | 1 Count | ## Product Details - **Brand:** TOTO - **Color:** Brass - **Connector Type:** Adapter - **Exterior Finish:** Brass - **Item Weight:** 0.27 g - **Item dimensions L x W x H:** 1 x 1 x 1 inches - **Material:** Brass - **Size:** 0.5 inches - **Thread Size:** 0.5 inch - **Thread Type:** NPSM ## Images ![TOTO TTHP3141 1/2" Adapter for Toto Washlet SW583 N/A - Image 1](https://m.media-amazon.com/images/I/41PSuoiBEDL.jpg) ## Questions & Answers **Q: What are the thread sizes for both sides of this adapter?** A: The male side is 1/2" male X 1/2" female **Q: Does this adapter include the 3/8 female to 3/8 male transition?** A: Amazon does sell an adapter that might do what you want .
