Lets keep going...

Pictures-

1. Cleaning the seals is important for tight fits. We will use garden hose in this DIY for cost and versatility. You can use different types of fittings and I will explain these later.

2. I like using clear flexible and black stiff tubing. Here you can see the 1/2 1/2 black inside the 1/2 5/8 clear. You force this into any garden hose and it will be such a tight seal, that you will get a workout trying to get it in or out, but you will know its safe. You have to insert the black inside the clear, then then clear end into the garden hose, then pull clear through other end of hose till black reaches the garden hose, forming a seal, then you pull it through- this requires just physical strength and a bit of lube if your that kind of person.

3. Once you've pulled it through, thats how it should look from the inside. Black opaque hose 1/2 1/2 in center, clear 1/2 5/8 around it, garden hose (standard type) outside of that. The hose has been pulled through with the black 1/2 1/2 forming the lock in the 1" hole. The garden hoses with the mat finish, rather than a glossy-slippery finish, work better because they don't slip around as much.

4. Here is another example of that self-sealing fitting that I used in another type of bucket- this is an unrelated design so do not let it confuse you. This picture illustrates how this connection has been a very easy, inexpensive, and versatile way for me to connect units within a system.

5. Pulling the hose through the hole to form an airtight seal...
