Bathtub Drain Fitting Kit

1. How to connect the overflow tube to the overflow elbow in a bathtub drain kit?

Plumberstar’s bathtub drain kit has a simple and reliable connection between the overflow pipe and the overflow elbow. It uses a sealed plug-in design. You don’t need complex tools. Installation is leak-proof, firm, and stable.

How to install:First, fix the overflow elbow to the bathtub overflow hole. Check that the gasket is in place. Make sure the sealing surface is clean and flat.

Then, align the overflow pipe with the elbow port. Most standard models use socket sealing. There is a silicone or rubber seal inside the port.

Push the pipe straight into the socket until it reaches the end. Make sure it fits tightly with no gaps. Some stronger models come with a fastening nut or clamp. After plugging in, you can gently tighten the nut. This presses the seal more tightly. It prevents the pipe from falling off and leaking.

You don’t need to use extra glue. This avoids pipe blockage from glue aging or bad installation. The whole connection uses a structural seal and a compressed gasket. It meets common bathroom installation standards. It is also easy to remove and maintain later.

After connection, you can pull the pipe gently to check firmness. Connect it to the main drain body. Then do a water test. Make sure the overflow works smoothly, and there is no leakage at the joint. Now the overflow pipe and elbow are fully installed.

5. What is the MOQ of the bathtub drain fitting kit?

As a professional valve supplier, Plumberstar has a flexible MOQ for bathtub drain kits. It fits foreign trade customers’ needs. It works for small trial orders, samples, channel replenishment, and large project orders.

For standard models with universal specs and existing molds, our MOQ is 500. This lets you place small trial orders. You can test the local market, get product certifications, or send samples to customers. New customers and small orders won’t feel pressured by high MOQ.

For non-standard drain kits, such as custom colors, logos, packaging, or special structures, the MOQ may vary slightly based on your custom needs. Custom orders require extra work: machine adjustments, line changes, electroplating, and packaging.

We will try our best to lower the MOQ. We only need to cover basic production costs. We want to help you promote the market and prepare for projects.

6. Has the bathtub drain fitting kit undergone 100% leak testing?

Plumberstar tests every bathtub drain kit 100% for leaks. We don’t just do random sampling.

Each product gets a full seal and leak test before leaving the factory. This stops seepage, leaks, and air leaks after installation.

We use professional water pressure testing equipment. We test key parts: drain body, overflow assembly, connecting elbow, and gasket. We apply standard pressure and hold it. We simulate real water flow and pressure. We check all joints, welds, and sealing surfaces.

Only products with zero leaks can go to packaging. This is a key part of our quality control. It meets strict plumbing and sanitary standards in Europe and America.

Whether for export, projects, or home use, you can install them safely and use them stably for a long time.

7. Can I change the specifications or quantity of the bathtub drain kit after the order is confirmed?

Before production start-up, the product specification and order quantity can be changed freely without extra cost.

During production, the price of the produced part and the mold opening fee for the new specification must be paid to change the product specification. The corresponding fee shall be paid according to the actual adjustment proportion for increasing or decreasing the order quantity.

After production is completed, the product specification cannot be changed. All changes must be confirmed in writing to avoid subsequent disputes.
