Standing Waste & Drain Tub Valves

(Also known as “Bi-Transit” drains.)

Once the standard, these beautiful fixtures are no longer being made.  There are 1000’s (if not Tens of 1000’s) still in use across the country today.

In response to the high number of emails we receive each week from people looking for repair and replacement options, we have added this informational page to our site to help spell out the available courses of action and to answer the most common questions.

Frequently Asked Question #1:

Q: “I have a funny tub faucet with the spout coming through the side of the tub. Do you have any repair parts for these?”
Short Answer: No.
Long Answer: Maybe. Send us your broken parts and we’ll see if the needed parts match any we have lying around, otherwise we will machine new parts to fit.

Really Long Answer: There are no “off the rack” brass repair parts available for these fixtures. Telling us about the make, model, and serial number really doesn’t help in these cases because there hasn’t been a parts-list printed in over 75 years.
Fully restored, these valves sell for around $3000+; as a result, we don’t “part out” complete assemblies. We do however have a 43-year accumulation of spare parts and can often adapt parts off a junked valve to work with your valve. In almost all cases, we can machine new parts as replacements in our shop. In either case, we need the original parts to work from.

Valve body and “Yoke” assembly

Picture at left shows a fully restored valve body and “Yoke” assembly. The yoke is the heart of the Standing Waste assembly, if your valve is missing the yoke, you have expensive problems! The yoke is the one part we cannot reproduce. If an over-zealous plumber hack-sawed this piece in half, we might be able to make repairs, if the piece is missing entirely, you may have to consider replacement options. We occasionally have complete Standing Waste assemblies for sale on our Restored Valves Page.

Frequently Asked Question #2:

Q: “I would like to replace my old lift-up tub drain with something that has an overflow, can you help?”

Answer: You already have an overflow! Standing waste drains are also called “bi-transit drains” due to their dual-tube construction. The picture at right shows a restored drain assembly. The tube in the center sits inside the large tube on the left and acts as a stopper. Notice the hole near the top of the stopper tube: That’s the overflow hole. As water fills the tub, it also rises unseen inside the large drain tube to the same level. The overflow hole is slightly below the rim of the tub. When water reaches the overflow hole, it runs down the center of the hollow stopper tube and down the drain.

Frequently Asked Question #3:

Q: “I have an old standing waste tub valve and want to add a shower. Is there anything available or do I have to replace the whole thing?”

Answer: We at Bathroom Machineries have devised a way to machine your existing tub spout to accept a riser and tub spout. This not only adds shower convenience to the tub, it brings it up to “code” by placing the spout more than 1″ above the rim of the tub.

If your valve is in good condition, all you need to send us is your spout. The two common styles of spout are pictured below. “Elephant trunk” spouts are easily machined to accept a riser, bell filler-style spouts (shaped like hockey pucks), sometimes must be replaced with a custom fitting.

Standing Waste Shower Conversion, see photo below at left.  These units are custom made to your specifications.  Please allow 6-8 weeks of lead time (at minimum) for one of these units.  For more information, either call us or e-mail us.

Standing Waste Code Spout Conversion:  Sometimes a shower isn’t needed but due to the sale or remodeling of the home, the original standing waste is flagged by a building inspector for not being anti-syphon code compliant.  (Spout is not 1″ above the rim of the tub.) The spout at left bottom shows a custom gooseneck spout we manufactured and fitted to the customer’s original elephant trunk spout which was then inverted. This allowed the customer to bring his standing waste up to code without the cost of replacing the fixture and without having to remove an historically appropriate fixture from his vintage home and replace it with something inappropriately modern.

“Elephant trunk” style standing waste spout

Close-up of “elephant trunk” style standing waste spout. Easily adapted for riser. Don’t break this while removing it, to cast a new one from scratch, machine it, polish, and plate it is about $600! Tell your plumber to take it easy!

Close-up of bell filler spout. This is often mistaken for the overflow. (Looks sort of like a hockey puck, doesn’t it?) Note the slot in the bottom where the water comes out. We can usually adapt these to accept a riser but may have to replace them entirely if the spout is badly corroded. Warning!, these are also about $600 to replace!

(Spout is not 1” above the rim of the tub.) The spout at left shows a custom goose-neck spout we manufactured and fitted to the customer’s original elephant trunk spout which was then inverted. This allowed the customer to bring his standing waste up to code without the cost of replacing the fixture and without having to remove an historically appropriate fixture from his vintage home and replace it with something inappropriately modern.

Frequently Asked Question #4:

Q: “I want to completely replace my standing waste with a ‘regular’ drain and new faucet. Is there anything available to do this?”

Answer(s): The first thing we need to know is if your valve has the spout near the rim of the tub (roughly where the overflow would go on a ‘regular’ tub), or if it is down low near the drain. Scroll to the very top of this page and look at the “high-bell filler” and “low-bell filler” valves pictured above.

If you have the low-spout valve, you are pretty much stuck using a standing waste-type drain and fill valve. Short of refinishing the tub and having the hole in the side filled, your best option is to rebuild your existing parts or purchase a restored fixture. It may be possible to plug the filler spout from the back side of the tub and use another type of valve until a more permanent, attactive solution may be employed.

If you are fortunate enough to have a high-spout valve and the tub is a single wall cast iron tub, a standard tub drain may be used, the overflow cover will fit the hole formerly occupied by the spout. The tub may then be filled “over the rim” with a Freestanding Tub Supply set.

If the hot and cold handles on the old valve are mounted through the rim of the tub, a deck-mounted valve or combination of swing-arm and deck-mount couplings may be used to mount one of our 79-series tub valves to the rim of the tub.

Swing Mounting arms and deck mount couplings

Swing Mounting arms and deck mount couplings pictured at right may be used on most 79-series tub valves to hit “oddball” center-to-center measurements. Perfect for replacing standing waste valves mounted in the rim of the tub on 6” to 11” centers.

The Bottom Line: Standing Waste & Drain Valves are rare, valuable antiques that are neither cheap nor easy to replace. When you consider that a fully restored Standing Waste sells for anywhere between $3000 and $4000, however, the value added to one’s home by keeping the original fixtures intact usually offsets the $1500 to $3500 average restoration cost. If this proves to be a “budget breaker”, other options are always available. The Bathroom Machineries Restoration Crew are Problem Solvers you can count on to guide you through the available options. Feel free to email or call us at 209-728-2031 if you have any questions or wish to discuss the options.
