Every water slide rental includes professional delivery, setup, and breakdown. But Manorhaven families often discover they can create an entire entertainment experience by adding bounce houses, dunk tanks, or carnival games to their package.
Our slides come with built-in safety features including safety nets, entrance ramps, and properly sized splash pools. These aren’t backyard inflatable toys – they’re commercial-grade equipment designed for safe, repeated use at events of all sizes.
Many Manorhaven residents use our services for birthday parties, but our equipment works equally well for school functions, community events, and corporate gatherings. The same attention to safety and quality applies whether you’re hosting 15 kids or 150 guests.
Most residential water slides need about 30 feet of length and 15 feet of width, with at least 4 feet of clearance on all sides for safety. The height clearance varies by slide, but most require about 15-20 feet overhead space.
Before your rental date, we will confirm your space meets the requirements for your chosen slide. We’ve set up in hundreds of Manorhaven backyards and can recommend the best slide size for your specific space.
If your yard has limitations, we offer smaller slides or can suggest combination units that provide water fun in a more compact footprint. The goal is finding the right fit for your space and guest list.
Every commercial-grade water slide includes built-in safety features like entrance ramps, safety nets, and properly designed splash pools. Our equipment is inspected before each delivery and meets all safety standards for commercial use.
We provide safety guidelines and require adult supervision during use. We also include ground stakes and proper anchoring to ensure the slide stays secure throughout your event.
As a licensed and insured company, we maintain comprehensive liability coverage. However, the renter is responsible for ensuring guests follow safety rules, including age and weight restrictions, and that an adult supervisor is present at all times.
You’ll need to provide access to water and electricity at your Manorhaven location. Most slides require a standard garden hose connection and access to a regular household electrical outlet within 100 feet of the setup area.
The water keeps the slide surface slippery and fills the splash pool. The electricity powers the blower that keeps the slide inflated throughout your event. These are standard requirements that most residential properties can easily accommodate.
If your setup location is more than 100 feet from power, let us know when booking. We can provide extension cords or discuss generator rental options to ensure your slide works perfectly regardless of your yard layout.
For peak season (May through September), booking 2-3 weeks in advance ensures you get your preferred date and slide choice. Weekends and holidays book fastest, especially for popular slide sizes.
During busy periods, waiting until the last week often means limited selection or no availability. Manorhaven residents have learned that early booking also gives them first choice of the newest and most popular slides.
Off-season bookings (spring and fall) offer more flexibility, but we can sometimes accommodate last-minute requests if equipment is available. Weather policies protect you if conditions aren’t suitable for your outdoor event.
The rental price includes the slide, professional delivery to Manorhaven, complete setup with safety features, and post-event breakdown and removal. You also get safety instructions and emergency contact information.
Setup includes proper anchoring, connecting water lines, testing all safety features, and ensuring the slide is ready for immediate use. Breakdown involves deflating, cleaning, and removing all equipment from your property.
Additional services like attendants, extra water hoses, or combination packages with bounce houses or games are available for an additional fee. Many families find the all-inclusive approach eliminates surprise costs and makes budgeting easier.
Yes, water slides work great for community events, school functions, and permitted park gatherings in Manorhaven. Many local organizations use them for fundraisers, field days, and community celebrations.
You’ll need to verify that your venue allows inflatable rentals and has the necessary water and electrical access. Some locations may require additional insurance documentation, which we can provide as a licensed operator.
The setup requirements remain the same regardless of location – adequate space, power access, and water connection. Our delivery team has experience with various Manorhaven venues and can advise on logistics for your specific location.
