Abstract
Abstract A cleaning system which is centrally and permanently installed in homes or commercial buildings and is connected to the water line therein. The system includes a pump operably attached to the water line and one or more freeze-proof valves are connected to the outside wall of the building or to an adjoining building. A fluid conduit is operably attached to the pump outlet and at the other end to the inlet of the freeze-proof valve. A spray wand, including an outlet nozzle, is attached to the freeze-proof valve on the outside of the building or buildings and includes structure for easily connecting or disconnecting such spray wand so that it can be removed when not in use and used at any one of the freeze-proof valve outlets. One or more chemical solutions can be selectively introduced into the fluid passing through the high pressure line. A wireless remote control is provided for permitting selections of the chemicals to be used at any one time and also to select the water temperature, or any combination of the above.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
212 words
Apparatus comprising: an enclosed building having outside walls; a water line substantially permanently installed and plumbed inside said building for supplying water at a pressure in a first pressure range; a pump substantially permanently installed and plumbed inside said building said pump having an inlet operably attached to said water line and an outlet for delivering water at a pressure higher than that of the pressure of said first pressure range through a fluid line substantially permanently installed and plumbed for passing fluid at a higher pressure than the pressure in the first pressure range, a valve connected to one of said outside walls, said valve having an inlet port and an outlet port; a fluid conduit substantially permanently installed and plumbed inside said building operably attached at one end thereof to said pump outlet and at the other end thereof to the inlet port of said valve; a spray wand outside said building, said spray wand including an outlet nozzle; means for selectively, operatively connecting or disconnecting said spray wand to said outlet port of the valve; means for operably introducing a cleaning chemical into fluid passing through said fluid line; and wireless remote control means for selectively turning said pump on or off from a location outside of said building.

212 words
Apparatus comprising: an enclosed building having outside walls; a water line substantially permanently installed and plumbed inside said building for supplying water at a pressure in a first pressure range; a pump substantially permanently installed and plumbed inside said building said pump having an inlet operably attached to said water line and an outlet for delivering water at a pressure higher than that of the pressure of said first pressure range through a fluid line substantially permanently installed and plumbed for passing fluid at a higher pressure than the pressure in the first pressure range, a valve connected to one of said outside walls, said valve having an inlet port and an outlet port; a fluid conduit substantially permanently installed and plumbed inside said building operably attached at one end thereof to said pump outlet and at the other end thereof to the inlet port of said valve; a spray wand outside said building, said spray wand including an outlet nozzle; means for selectively, operatively connecting or disconnecting said spray wand to said outlet port of the valve; means for operably introducing a cleaning chemical into fluid passing through said fluid line; and wireless remote control means for selectively turning said pump on or off from a location outside of said building.
Claim 3
Dependent Claim
15 words
The apparatus of claim 1 wherein said wireless remote control means operates on radio frequencies.
Claim 4
Dependent Claim
17 words
The apparatus of claim 1 comprising means for operably introducing a second chemical into said fluid conduit.
Claim 5
Dependent Claim
35 words
The apparatus of claim 1 wherein said water line includes a cold water line and a hot water line and connection means for selectively connecting or disconnecting said hot water line from the pump inlet.
Claim 6
Dependent Claim
36 words
The apparatus of claim 1 comprising a pressure relief valve in said fluid conduit for releasing fluid when pressure within said fluid conduit exceeds a predetermined amount, said relief valve having an inlet and an outlet.
Claim 7
Dependent Claim
23 words
The apparatus of claim 5 wherein said pressure relief valve outlet is fluidly connected upstream of said pump inlet through a relief conduit.
Claim 8
Dependent Claim
28 words
The apparatus of claim 6 including means in said relief conduit for turning off the pump when the fluid temperature in the relief conduit exceeds a predetermined level.
Claim 9
Dependent Claim
20 words
The apparatus of claim 1 wherein said valve includes means for preventing said valve from freezing due to outside temperatures.
Claim 10
Dependent Claim
152 words
A freeze-proof valve comprising: a valve body having an inlet port and an outlet port; a valve seat in said valve body in fluid communication with said valve inlet port; a valve head disposed in said valve body and having a closed position in sealing contact with said valve seat and an open position spaced from said valve seat; a fluid passageway associated with said valve body for connecting said valve inlet port to said outlet port when said valve head is in said open position; means for biasing said valve head to said closed position thereof; handle means on the outside of the building for selectively overcoming the biasing means to move the valve head to said open position thereof; and pressure means associated with said valve head for causing said valve head to remain in said open position in response to a buildup of pressure upstream of said valve head.
