Flexible Toilet Seal Adaptable to Conduits of Different Size and Related Method
The present disclosure generally relates to a toilet seal that is adaptable to conduits of different size. In one embodiment, the seal includes an integral sealing element coupled to an end of the sleeve. A modular sealing element is further disposed about the integral sealing element. The modular sealing element and integral sealing element are removable to thereby adapt the seal to conduits of different size. In another embodiment, the seal includes a first integral sealing element coupled to an end of the sleeve. The seal further includes a second integral sealing element coupled to the first integral sealing element. The first and second integral sealing elements are removable to thereby adapt the seal to conduits of different size. Related methods are described.
The present disclosure relates generally to devices for connecting conduits, such as plumbing fixtures to waste drainpipes, and more particularly to a toilet seal.
BACKGROUNDWater closets, also called toilets, are waste disposal devices commonly installed in most bathrooms. These kinds of plumbing appliances generally include a water-storing receptacle called a water tank that is attached to a siphon seat-shaped bowl called a toilet bowl. Periodically, waste is removed from the toilet bowl by flushing, thereby allowing water to drain from the water tank through the toilet bowl and into a waste drainpipe. In such arrangements, the toilet bowl is typically connected to the waste drainpipe by fluid carrying conduits and the toilet bowl will sit flat on a floor and connect with a rigid water closet flange. The water closet flange in turn connects with conduits leading to a waste drainpipe.
Conventional water closet flanges are often used with wax seals that are disposed about a discharge horn extending from the toilet. Such seals can be unreliable because the seal connection is not strong enough to prevent leakage and associated odors, and oftentimes they can be expensive and inefficient due to delays in the installation process. Also, conventional water closet flanges are fixed in diameter, and are thus unable to adapt to conduits of different size. This requires multiple seals for any particular job as the size (i.e., diameter) of the conduit is oftentimes not known until the installation process begins.
Improved toilet seals for addressing the above-described problems are desired. Related methods for installing improved toilet seals are also desired.
BRIEF SUMMARYThe present disclosure generally relates to improved toilet seals and methods for installing such toilet seals. In one exemplary embodiment, a toilet seal according to the present disclosure includes a sleeve having an integral outward-facing sealing element coupled to a first end of the sleeve and an additional inward-facing sealing element comprising an inwardly extending flexible lip disposed at a second end of the sleeve. The outward-facing sealing element has an increased outward diameter relative to the sleeve. In some embodiments, the sleeve has a sufficient degree of flexibility to accommodate connection between misaligned, angled, or otherwise incongruous plumbing fixture discharges and waste drainpipe outlets. In other embodiments, the sleeve takes on a more rigid configuration. The inwardly extending flexible lip provides a desired seal between the plumbing fixture discharge and the waste drainpipe (or conduits leading to the waste drainpipe), thereby eliminating the need for a separate gasket element, such as a wax seal or rubber foam seal.
The flexible toilet seal according to the present disclosure may be adapted for use with conduits of different size. Accordingly, an additional modular sealing element may be coupled to the integral outward-facing sealing element to provide an increased outward diameter to thereby adapt the toilet seal for use with larger diameter conduits. To accommodate conduits of smaller diameter, the sleeve may include a coupling portion defined adjacent to the integral outward-facing sealing element to allow for quick detachment of the integral sealing element to thereby reduce the diameter of the toilet seal at the downward portion thereof.
In other embodiments, the flexible toilet seal according to the present disclosure includes multiple integral outward-facing sealing elements of different diameter. The portion of the seal adjacent the integral outward-facing sealing elements includes coupling portions defined between the sealing elements to facilitate quick-detachment of the lowermost sealing element to thereby adapt the toilet seal to conduits of different size.
Related methods for installing toilet seals described herein between plumbing fixture discharges and waste drainpipes (or conduits leading to waste drainpipes) are also described.
Reference is now made to the following descriptions taken in conjunction with the accompanying drawings.
Various aspects of a toilet seal and related methods for installing and adjusting the toilet seal according to the present disclosure are described. It is to be understood, however, that the following explanation is merely exemplary in describing the devices and methods of the present disclosure. Accordingly, several modifications, changes and substitutions are contemplated.
The toilet seal 10 further includes an inward-facing sealing element 20 disposed about an upper end of the sleeve 16 to thereby engage and seal a plumbing fixture discharge as will be described. Preferably, the sealing element 20 includes a flexible lip 22, which extends inwardly. The inward-facing sealing element 20 may further include a ring portion 24 extending beyond the circumference of the sleeve 16 to provide support for the sealing element in seating against a flange or conduit.

The sleeve 16 includes an additional sealing element 42 disposed circumferentially about the sleeve 16 proximate a lower end of the sleeve after the integral sealing element 18 has been removed. The sealing element 42 provides a seal between the sleeve 16 and an inside surface of the conduit 12. The sealing element 42 may take on a variety of configurations so long as it seals the interface between the seal 10 and the conduit 12 or flange 14. In some embodiments, such as those shown in
Referring now to
The toilet seal 100 further includes a pair of integral sealing elements 110, 112, which are coupled to a lower end of the sleeve 104. The outward-facing sealing elements 110, 112 may take on a variety of configurations so long as they seal the interface between the seal 100 and the conduit 12 or flange 14. In some embodiments (such as those shown in the Figures), the sealing elements 110, 112 may have a substantially uniform diameter. However, in other embodiments, the sealing elements 110, 112 may be configured to have a maximum diameter at a region generally corresponding to an upper portion thereof, and a profile that generally decreases in diameter to a lower portion thereof. In still further embodiments, the sealing elements 110, 112 may have an increasing diameter from a lower portion to an upper portion, or a varying diameter.
In addition, a modular or integral sealing element 114 is disposed about the sleeve 104 longitudinally above the sealing elements 110, 112. The sealing element 110 is preferably coupled to an end of the sleeve 104, while the sealing element 112 is coupled to the sealing element 110. Furthermore, while two sealing elements 110, 112 are shown, in other embodiments, additional modular or integral sealing elements may be provided.
The toilet seal 100 is adaptable to conduits of different size, and as such, the toilet seal may be modified for particular uses. Referring to
The sealing element 112 may be removed by cutting through the coupling portion 116 of reduced thickness to thereby separate and remove the sealing element 112 from the remainder of the toilet seal. In this manner, the toilet seal 100 may be adapted for use with conduits having a smaller diameter as the lower end of the toilet seal has been reduced from the diameter of sealing element 112 to the diameter of sealing element 110. For example, in some embodiments, the sealing element 112 may be approximately 4 inches in diameter, while the sealing element 110 may be approximately 3.5 inches in diameter.
Referring to
The sealing element 110 may be removed by cutting through the coupling portion 118 of reduced thickness to thereby separate and remove the sealing element 110 from the remainder of the toilet seal. In this manner, the toilet seal 100 may be adapted for use with conduits having a smaller diameter as the lower end of the toilet seal has been reduced from the diameter of sealing element 110 to the diameter of sealing elements 114. In one example, upon removal of the integral sealing element 110, the diameter of the toilet seal 10 at the sealing interface with the conduit is 3 inches.
The sleeve 104 includes the additional sealing element 114 disposed circumferentially about the sleeve 104 proximate a lower end of the sleeve. The sealing element 114 provides a seal between the sleeve 104 and an inside surface of the conduit 12. The sealing element 114 may take on a variety of configurations so long as it seals the interface between the seal 100 and the conduit 12 or flange 14. In some embodiments, such as those shown in
Referring to an upper portion of the toilet seals 10, 100, for example as shown in
The plumbing fixture discharge 11 may be seated against the seal 10, 100 such that a horn portion 134 of the plumbing fixture discharge comes into contact with the inwardly-extending flexible lip 22, 106 thereby deflecting the lip downwardly. As shown in
Referring again to
In practice, the toilet seal 10, 100 is used to connect a plumbing fixture discharge, such as the horn portion of a toilet, to a waste drainpipe, such as a sewage line. In facilitating this connection, the toilet seal 10, 100 provides a tight seal and reliable connection to prevent any undue leakage or other undesirable consequence of the connection. During installation, the toilet seal 10, 100 may be seated against the toilet flange 14 (
