The defendants appeal from a judgment quieting title in the plaintiff to “that certain water distributing system including the pipes, situate in the Modesto High School Tract now in the possession of defendants and formerly connected to wells and pumping plants located upon Lots 7 and 8 in Block ‘D’ and Lots 22 and 23 in Block ‘B’ of the Modesto High School Tract”; directing the defendants to “reconnect the said pipes and the said distributing system to the aforesaid wells and pumping plants in as nearly as possible the manner *367 in which the same were at the time the defendants disconnected the same”; and decreeing that the ‘‘plaintiff is entitled to an accounting by defendants of all moneys received by said defendants from the operation of said pipes and distributing system from November 18, 1940, to the date of reconnection . . . as herein ordered.” The notice of appeal further recites that the defendants as cross-complainants appeal from the judgment in favor of the cross-defendant Baley.
There is no dispute concerning the material facts of this case: On February 21, 1939, and for several years prior thereto, the cross-defendant Baley was the owner of the four lots mentioned in the judgment as situated in the Modesto High School Tract, an unincorporated residential district adjacent to the city of Modesto. Upon this property were located two wells and pumping plants from which there extended a series of pipes furnishing water to approximately seventy neighboring homes at a monthly rate. On the date mentioned Baley executed to the plaintiff as security for his promissory note a deed of trust covering these four lots ‘‘together with the rents, issues and profits thereof; also all appurtenances including water rights in which trustor may have an interest, whether represented by stock of any water company or otherwise, benefiting the property herein described.” Thereafter, and on March 1, 1939, Baley sold these same lots to the defendants Moore, and by a separate conveyance he transferred to them the water distributing system. Upon default in the payment of the aforesaid promissory note the property was sold under the deed of trust, the plaintiff became the purchaser thereof at the sale, and the trustee’s deed was executed and delivered to her on November 18,1940. Some six months prior to these foreclosure proceedings the defendants Moore had disconnected the water distributing system from the pumping plants on the premises in question and attached it to a well and pumps installed on other lands owned by them. Under these circumstances the plaintiff brought the present action to have the distributing system reconnected and for an accounting with respect to the defendants’ operation thereof since the date of her purchase of the property at the trustee’s sale. The portion of the distributing system here involved lies entirely outside of the bounds of the lots described in the deed of trust and consists largely of pipes and mains placed in the streets and alleys of the Modesto High School Tract.
The trial court’s findings and its judgment rendered in favor *368 of the plaintiff, as in part above noted, establish that it took the following view of this case: (1) That the distributing system involved, although lying without the limits of the land described in the deed of trust, passed to the plaintiff as an appurtenance of the lots which she purchased at the trustee’s sale; and (2) that while “the Railroad Commission of the State of California did not authorize Ealey to execute said note and said deed of trust on said property,” the distributing system in question was not a public utility so as to require the commission’s order of authorization prior to the valid execution of the security instruments. (Pub. Util. Act, § 52(d); Stats. 1915, p. 115, as amended; Deering’s Gen. Laws, 1937, Act 6386, p. 3167.) Application of settled legal principles to the undisputed facts disclosed by the record herein sustains the trial court’s decision as premised upon the above two determinative points.
The first matter for consideration is the interest in the water system acquired by the plaintiff under the deed of trust. It appears from the record that for some time prior to the daté of execution of said security instrument the water piping system in question had been annexed and physically connected with the pumping plants on Ealey’s lots; that the piping as laid throughout the streets and .alleys was merely an extension and continuation of the apparatus for the production and distribution of the water supply—a part of it, and not separable from it without destroying the efficiency of the whole; and that the waterworks as so constructed were functioning as an integrated system when the loan arrangements between the plaintiff and Ealey were consummated, as above detailed. Appurtenances are things belonging to another thing as principal and which pass as incident to the principal thing. (Bouvier, Law Dict., Sub., Appurtenances.) Here the principal thing was the pumping works, and the piping system attached thereto was an incident to the main machinery—the pumps and the wells. Such pipe extension was necessary to the enjoyment of the principal thing and indispensable in the supply of water to the neighboring homes in the tract. By being so joined and essential to the function of the apparatus as a whole, the distributing system contained and combined in itself all of the elements and attributes of a fixture or appurtenance to real estate. (Civ. Code, § 662; 6 C.J.S. p. 133, et seq.)
Analogous considerations as to structural appendages were

involved in the case of
Western Elec. Co., Inc.
v.
Colley,
Similarly, where questions as to the property characteristics of a water distributing system have arisen in connection with tax assessment problems, the courts have declared the pipes, mains and hydrants of a water company to be appurtenant to and taxable with the real estate where the main works are located.
(Pasadena
v.
County of Los Angeles,
Thus upon both reason and authority the water distributing system here in question was appurtenant to the Ealey lots upon which the pumping works were located. As a general rule, a conveyance of property carries with it by implication all incidents rightfully belonging to, and essential to the full enjoyment of, such property at the time of conveyance. (26 C.J.S. § 106, p. 386, et seq.) In this state, under authority of section 1084 of the Civil Code, incidents and appurtenances to lands pass with a transfer thereof unless expressly excepted. (9 Cal.Jur. § 152, p. 286.) That the plaintiff and Ealey in executing the deed of trust here involved, intended the appurtenances to Ealey’s lots to be encumbered under the terms of that instrument is manifest from the specific inclusion therein of “all appurtenances . . . benefiting the property herein described.” There was no need for direct reference to the water piping system in order to have it covered by the language of said deed of trust, and Ealey’s subsequent property negotiations with the defendants could not affect the plaintiff’s rights established under the security instrument. The propriety of the plaintiff’s claim here is emphasized when considered in relation to the legal principles applied in the disposition of the case of
Harper
v.
Buckles,
“ ‘The rights of Bachman under the agreement are the same as those of Threlfall.
“ ‘It is immaterial that the mortgages of Threlfall’s land, under which Bachman acquired title, were executed before Threlfall obtained the water-right. The water-right, when acquired, became an easement appurtenant to the land
(Farmer
v.
Ukiah Water Co.,
The Harper opinion then continues (
Here, in contrast to the factual situation prevailing in the Stanislaus and Harper cases, supra, the water system in question was in place and functioning as a valuable adjunct to the Ealey premises when the deed of trust was executed by Ealey and the plaintiff. Upon the basis of legal principles governing the passage of title to appurtenances under a conveyance of the land, there would seem to be no practical difference between a piping system constructed to convey water to said land for use thereon and a piping system installed to convey water from said land, as part of the mechanical apparatus located on the premises. In either event the piping system is incident to and necessary to the beneficial enjoyment of the land so as to follow a transfer of the realty unless expressly excepted. In the light of this reasoning the conclusion is inescapable that the water distributing system here in question was covered by the plaintiff’s deed of trust on the Ijlaley lots; that her title to the encumbered property was established by her purchase at the trustee’s sale; and that the defendants were properly directed by the. trial court to reconnect said piping system to the pumping works on said lots and to rem der an accounting to the plaintiff as specified in the judgment.
Nor is the plaintiff’s position assailable upon the ground that the water system as maintained by Ealey was a public utility and subject to the order of the Railroad Commission, which admittedly did not authorize the security arrangements made with respect to the Ealey premises. Whether or not a water system is a public utility depends on the character of the business.
(Van Hoosear
v.
Railroad Commission,
Turning now to the attempted appeal from the judgment in favor of the cross-defendant Ealey, the following facts appear from the record. A cross-complaint was filed against Ealey and he was brought into the action as a cross-defendant by permission of the court. On January 15, 1942, in the course of the trial, the court made an order striking the cross-complaint from the files. The judgment was rendered on May 11, 1942, and it contains by way of recital only the statement “the cross-complaint having been stricken from the files upon motion of the cross-defendant.” Notice of appeal was filed on July 17,1942, and it purports to appeal only from the judgment entered on May 11, 1942.
The order of January 15, 1942, striking the cross-complaint from the files was as to Ealey the cross-defendant, not otherwise a party to the action, a final and appealable judgment.
