        "content": "Here\u2019s a breakdown of standard hose / T-valve sizes used in bidet attachments, and what accounts for the \u201cthicker\u201d vs \u201cthinner\u201d hoses you see out there. Use this to figure out what yours likely is, and what you'd need to match.\n\n---\n\n## Key Connections and Sizes\n\nWhen installing a bidet attachment, there are generally three crucial hose connections / thread sizes to keep in mind:\n\n| Location | Typical Thread / Fitting Size |\n|---------|-------------------------------|\n| **A. Under the toilet tank (fill-valve outlet / \u201cballcock\u201d)** | *7/8-inch* (most common in the U.S.) ([totvalve.com](https://totvalve.com/bidet-t-valve-guide-finding-the-right-t-adapter-for-your-toilet-water-line/?utm_source=openai)) |\n| **B. At the shut-off (angle) valve on the wall** | *3/8-inch* compression is standard in many U.S. homes; *1/2-inch* in some older homes or certain regions outside the U.S. ([totvalve.com](https://totvalve.com/bidet-t-valve-guide-finding-the-right-t-adapter-for-your-toilet-water-line/?utm_source=openai)) |\n| **C. The hose feeding the bidet\u2019s inlet (from T-valve side-port to bidet)** | Can vary: commonly *3/8-inch* or *1/2-inch*. The bidet will usually come with a hose that matches the side-port size on the T-valve. ([totvalve.com](https://totvalve.com/bidet-t-valve-guide-finding-the-right-t-adapter-for-your-toilet-water-line/?utm_source=openai)) |\n\n---\n\n## What Makes a Hose \u201cThicker\u201d vs \u201cThinner\u201d\n\nThese size designations aren\u2019t just for show. They correspond to differences in internal diameter (ID), which affect water flow rate and fit:\n\n- A **thicker hose** usually refers to one with larger fittings (like 1/2-inch ID or large thread) or one that matches a 1/2-inch supply line.\n- A **thinner hose** often refers to smaller fittings (3/8-inch), which are sufficient for most bidet sprays. These are lighter, more flexible, and fit in tighter spaces.\n\nAlso, the diameter on the hose threads/bushings (outside) will need to fit into the receiving nut without leaks, so matching threads is critical\u2014not just inner diameter.\n\n---\n\n## Examples & Specs from Manufacturers\n\n- **Samodra Bidet** (U.S. models) often use a 9/16-inch thread at the toilet tank fill-valve, and 3/8-inch on the hose to the bidet unit. ([samodrahome.com](https://www.samodrahome.com/pages/product-size?utm_source=openai))  \n- **Brondell SimpleSpa Eco** specs list a **\u215e-inch T-valve** in/out under the tank, and **\u215c-inch** hose fittings to feed the bidet. ([brondell.com](https://www.brondell.com/content/SSE_25_SpecSheets_122722.pdf?utm_source=openai))  \n- **Boss Bidet** guide: 7/8-inch is universal under-tank, 3/8-inch versus 1/2-inch depends on valve sizes. ([bossbidet.com](https://bossbidet.com/pages/bidet-t-adapter-sizes?utm_source=openai))  \n\n---\n\n## What to Measure to Determine Your Hose Size\n\n1. **Under the Toilet Tank**  \n   Unscrew the supply line nut from the fill-valve standoff (from tank). Measure fitting diameter; in the U.S., this is almost always 7/8-inch.\n\n2. **At Your Wall Shut-off Valve**  \n   Check the supply line that runs from the wall to the toilet (or where you want to split to feed the bidet). Most use 3/8-inch compression fitting in U.S. residential. If yours is larger, it might be 1/2-inch.\n\n3. **Bidet Inlet Side-Port Size**  \n   Look at the hose and T-valve branch that goes from the side to the bidet attachment. It\u2019ll say 3/8, 1/2, etc. This needs to match the hose you use from T-valve to the bidet.\n\n---\n\n## Typical Pairings & What\u2019s \u201cStandard\u201d\n\nIn summary, these are the most common \u201cstandard\u201d pairings in U.S. bathrooms for bidet attachments:\n\n- **Tank to T-valve connection**: 7/8-inch thread  \n- **Wall/angle stop valve**: 3/8-inch compression  \n- **Hose from T-valve side-port to the bidet**: 3/8-inch (often), sometimes 1/2-inch depending on bidet model  \n\nIf your hose looks \u201cthicker,\u201d it may have larger fittings (1/2-inch) or be built for heavier flow or for outside-U.S./non-imperial standards. If it\u2019s \u201cthinner,\u201d it likely is 3/8-inch.\n\n---\n\nIf you have pictures of the hose ends or the stamped numbers/fittings, I can help you figure out exactly which size you\u2019ve got\u2014and what you\u2019d need to get if you want a replacement or adapter."

That means the fill-valve/tank inlet uses \u215e\u2033 threads on both the tank side and the supply line side, with the side branch to the bidet hose using \u215c\u2033.

        "content": "Yes \u2014 in many cases you *can* reuse the hose you currently have for your Brondell Swash when installing a Brondell SS-150, *as long as* the hose fits the required connection sizes and is compatible in terms of length and material. Whether it works well depends on a few specific fitting details. Let\u2019s walk through what those are and how to check.\n\n---\n\n## SS-150 Hose & Connection Requirements\n\nFrom the Brondell SS-150 user manual:\n\n- The T\u2010Valve that connects at the toilet fill valve underneath the tank requires the **top connection** to be a **\u215e\u2033 ballcock** thread. ([brondell.com](https://www.brondell.com/content/SimpleSpa_SS150_OwnersManual_112320.pdf?srsltid=AfmBOork7tn3fl__iJKNZWUrva0dVr-M2PUAb9posRAe0Jxqx-Cu0Y6F&utm_source=openai))  \n- The **bottom connection** to the wall shut-off valve should be either **\u215c\u2033** or **\u00bd\u2033 female compression**, depending on what your shutoff valve uses. ([brondell.com](https://www.brondell.com/content/SimpleSpa_SS150_OwnersManual_112320.pdf?srsltid=AfmBOork7tn3fl__iJKNZWUrva0dVr-M2PUAb9posRAe0Jxqx-Cu0Y6F&utm_source=openai))  \n\nSo: the hose (or the fittings of the hose or any adapters in between) needs to match those sizes \u2014 one end \u215e\u2033 ballcock, the other either \u215c\u2033 or \u00bd\u2033 compression.\n\n---\n\n## What Swash Hoses Use (Typical)\n\nSome specifics for Brondell Swash models:\n\n- Most Swash bidet seats and many non-electric seats utilize a standard **\u00bd\u2033 hose connection** for the hose running from the T-Valve to the seat. ([help.brondell.com](https://help.brondell.com/hc/en-us/articles/34577017167117-International-Purchasing-Shipping-Policy?utm_source=openai))  \n- The replacement hoses Brondell offers for Swash models are *model-specific*, with set lengths and fittings, implying there\u2019s a range of sizes depending on the exact Swash model. ([brondell.com](https://www.brondell.com/swash-replacement-bidet-hoses/?utm_source=openai))  \n\nBrondell also makes replacement T-Valves for SS-150/250 attachments that match the \u201cSimpleSpa Cold T-Valve\u201d dimensions. ([brondell.com](https://www.brondell.com/bidet-attachment-t-valve-replacement/?utm_source=openai))\n\n---\n\n## Will Your Current Hose Work?\n\nIt will work **if**:\n\n1. The end of your current hose that attaches to the toilet fill valve has a \u215e\u2033 ballcock or compatible fitting.  \n2. The other end matches your shut-off valve\u2019s compression size (\u215c\u2033 or \u00bd\u2033), or already has or can use an adapter to the proper size.  \n3. The hose is long enough (or can reach comfortably) without strain.  \n4. The hose material and fittings are in good condition (no leaks, corrosion, cracked metal, etc.).\n\nIf any of those don\u2019t line up, you\u2019ll need either:\n\n- A hose with the correct fittings and length, or  \n- Adapters or converters to go from your existing hose\u2019s sizes to what the SS-150 requires.\n\n---\n\nIf you want, I can help you check your specific Swash model\u2019s hose sizes (just tell me the model) and see whether it matches the SS-150, or what adapters you'd need if it doesn\u2019t."
