has Clawfoot Tub Drains, Vintage Tub & BathKingston Brass CC2093, and how to install Plumbing for a Claw Foot Tub.

Do I need to install a vent on the clawfoot tub?The tub is being renovated as part of the project.The overflow tube under the faucet connects directly to the drain below.

You need a vent.The tub is the same as any other.The vent should be in place if you haven’t changed the plumbing.The trap would be under the floor near the drain and vent.You need to fix the plumbing if you have already changed it.If you’re going to change the plumbing and don’t know that you need a vent, you should get a plumbing book.

Your arrogant “and don’t even know that” response is unwarranted.I have a lot of practical experience in the construction and design trades.

A quasi-Queen Anne style house was built in 1921.The house was built without a stack vent.I ran vent to each fixture and added a proper stack vent.I’ve replaced the entire cast iron DWV system with new hubbed cast irons, except for the bathroom I write about.

lawfoot tubs are not the same as other tubs.The tub is original to the house.The vent system is part of the drain.A similar system is used on a modern tub for overflow protection and to house the drain lever linkage.This type of system was only used for overflow protection.A cast 1 3/8″ pipe is terminated with a right angle and a low resistance grate on the inside of the tub.A clawfoot tub of this era would not have a seperate vent.The installation of the traps was the same as it would be today.

A 1 1/2 modern vent added to this configuration will not aid in drainage.The short section of vent pipe has less resistance than the long section.

I am aware of what the code says.Since the tub will be installed against two plaster over brick walls, it’s impossible to hide a vent, so I’m only trying to use common sense.

Fresh air can be allowed to circulate through the vent system.Without a modern vent, the 6 foot horizontal run from the tub trap to the stack will not be subject to this type of ventilation.

It may not be to code, but common sense tells me that with only 6 feet to your stack, and the integral tub vent system you clearly described, your tub should drain perfectly.

It took me three readings to get that pun, PDennis, let me know where you get your fixtures for the clawfoot tub.I have one source, but I would be interested in another.I also have a clawfoot tub, and the faucet leaks, I suspect from damaged washers and valve sets.

Mike is correct that you need a vent downstream from the trap.You may be able to add a vent like the one used in mobile homes.

If it is on the stack side of the trap, your tub “overflow vent” will only work as a vent.It is a great place for sewer gasses to enter your bath room if it is on the stack side of the trap.He didn’t know you were a pro.I don’t see arrogance in his reply.

The claw foot tub has overflow tubes.Every tub has a waste and overflow plumbed in.Since it is on the fixture side of the trap, the overflow does nothing more than the drain itself.A proper vent is needed.Ask your building inspector if you still doubt that.You can’t locate the vent from the trap if you have a fixture drain.5′ is allowed for a 2′ pipe.I can’t remember what is allowed for a 1.5 inch pipe.You can increase the size of the “dirty arm” if you need to locate the vent farther from the fixture.You seem to have made up your mind that a vent is not necessary and are looking only for justification of that oppinion, not practical, common sense advice.

Antique Hardware & Home Store and Renovators are both good places to buy clawfoot tub stuff.The tub isn’t to code.Since 1920, a lot of code has changed.Did they have code then?

Dennis, try your local plumbing store.The one where I live sold me some products from a manufacturer called “Sign of the Crab”.I bought a tub fixture that had porcelain handles, a gooseneck faucet, and a telephone shower.They also had an upright shower for a cast-iron tub.They made basin cocks.Old-house restoration has become popular and there’s a lot of stuff out there.

If you don’t want short and sweet advice on the correct and legal methods, look elsewhere. How would you expect your local buildind official to?

Thanks Mike and all.I will work a legitimate vent into the design.All the pros are willing to help a non-pro.

I’m still working on the fixture for the tub.I bought a shower ring and faucet from Renovator’s Supply.I sent it all back.I won’t get into gory details here, but anyone who would like more information can e-mail me at [email protected].I would’ve seen the negative feedback about Renovator’s if I’d checked Breaktime first.

Restoration Hardware has good results for smaller items.They have a good collection of reproduction towel bars.You can test drive everything at the retail outlets.

The tub feet on my tub were done by Harley Davidson, and they did a great job, at half the price of new.

Contrary to popular opinion, the sole goal of building officials is not to make builders lives difficult.Building officials want to retire with a good pension and benefits.They have a good chance of realizing this goal since they are not self-employed.Some self-employed building officials make money by helping contractors through difficult situations, but there is not a large market for them.If it weren’t for the vigilance of contractors, building officials would not be dropping a lot of hundred dollar bills on job sites.

The biggest threat to building officials retirement plans is job security, not self-employment.Building codes are written to protect their retirement.They can’t just write a code that guarantees them retirement and then go home and wait until they’re 65 to start collecting, so they make up some arcane rules that only they understand.

Help the building inspector find his or her lost hundred dollar bills is the best way to deal with this situation.Installation and removal of the questionable component is an alternative.This works with unnecessary stuff, but shouldn’t be used with floor joists, trusses or sheeting.The second method is not cost efficient except on tracts where the removed components can be installed on the next unit for its inspection.
