Rolling Hot Tub

It all started one day at my brother-in-laws house….
ME: So, where’d you get the hot tub man?
B-I-L: From a neighbor
ME: What’d it cost ya?
B-I-L: Nothing, just had to roll it down here.
ME: You gonna set it up?
B-I-L: Na, too much work, the cabinet is rotted. You want it?
ME: (duh) YEAH!

So my wife and I commenced to hauling it sans the cabinet to our place for installation. My brother-in-law hasn’t seen it installed at my place yet, but I bet he’ll want it back….

This was a rather short installation process given that I did 99% of everything alone. It took me an evening to the tub hung and 4 days to plumb and do the whole deck.

Below is what I did. You can skip to the notes section here.

Here’s what I did:
I documented EVERYTHING mechanical on the old setup. Pix here:

It’s mine so now I have to move it… don’t have pix, but needless to say doing it in the dark with four people, my brand new-never-scratched-not-even-hauled-anything-yet-Truck didn’t help any. Again- I left the old cabinet behind and took the tub and all the plumbing/electrical.

Next you have to put it some where. I had an unused corner of the house that was perfect for it. Pix here:

The Actual Install…

I decided to “hang” the tub against the house. It really doesn’t hang, but it looks like it. It has support on the absolute bottom and lots of support on the sides. The bare frame looks like this:

Keep in mind, at this point things are VERY rough. I decided to use two of those “foundation blocks” to hold up a set of 4x4s. They handle the weight like a champ and there really wasn’t much prep for putting them down.

I did a temporary plumb-as-it-is water test to see where the leaks were and how bad the plumbing was. The leak was were where I expected it- the spot where I took out a jet…

Notice when I did the plumb-it-as-it-is test, the plumbing wasn’t very good. In fact it was SO bad that I had to replace the heater unit. The idiot that installed it GLUED joints DIRECTLY to the heater. I’m talking joints on joints on joints, no threaded joints in case you ever have to remove it!!! DUH! Cut one and you can’t get anything back together. Not to mention the fact that the inside of the heater was in horrible condition. Check the pix:

Now look at this one, you can really see how bad the heater was, look in the middle of the pic and look at all the turns the pipe made from the filter to the heater!!!!

So that was the original plumb job…geez. Now that the plumbing is setup for a basic test, one must do a temporary electrical next….So out comes the computer power cable, some wire nuts and some wire stripping.

Ok, so it all works now we have to do version 1 of the plumbing, finish the real-to-local-code wiring and finish up the deck.

The final electrical is in conduit, has a dedicated circuit out of the main panel (not a sub panel) and is covered:

I decided to do a two part deck, one around the tub at tub level and one on the ground around the tub and up to the back door. Deck one looks like this:

The bottom deck actually sits on the ground (using pressure treated wood). Pictures tell this part of the story, they are pretty much in construction order from left to right.

Now with an awesome deck, we need a hot tub. Since I replaced the heater I got a new controller too, this handles making sure the heater isn’t on when the pump isn’t etc. Well, the first heat up has taken over 48 hours and hasn’t made it above 90 degrees. I even put my 500 watt fish tank heater in there. Without that it wouldn’t have made it that far! See the heater:

So, a call the manufacturer is warranted. I already opened everything, checked voltages, checked to see that the switches that handle the heating element are working, making sure none of the safety switches are off etc, etc. I really think the only reason we got to 90 degrees was the fish tank heater!!!

After receiving a new heater via over night shipment (Thanks Spa Babes!), the new heater was installed and heating. 24 hours later we had a 105 degree hot tub- no fish heater needed!

Final Pictures!!

  • This one sounds like common sense, but don’t believe it. I had a really nice cordless drill with a DIY super amped battery for when the other two die. Dropping a cordless drill on accident or otherwise into water is BAD. While I was able to save it with some WD40, it only worked for a week after that and then totally shorted out- smoke and all. I did get a nicer drill, but dang it I liked my old drill!
  • It helps to have a somewhat portable saw mill. Mine is a radial arm saw. I prefer this for some reason over table saws for certain cutting.
  • Put valves and unions before and after the pump, heater and filter equipment!!!! If you need to change anything this will keep most of your water in the tub and allow you to disconnect the equipment without cutting the pipe! Unfortunately I was in such a rush to get this working I remembered to put threaded fittings on everything, but not valves or unions….(update: I finally put in unions and on/off valves, it took the replacement of the filter unit before I cared enough to do it, but maintenance is so much easier!)
  • Chemicals– I have never ever used chlorine in my pool or hot tub. It smells funny, bleaches your clothes and hurts your eyes. There are three alternatives that I know of right now. Bacquacil, SoftSwim (by BioGuard) and Clear Comfort by Omni. I am a Bacquacil defectee only because the dealer in the area is a total ass and has no concept of customer service (take note Bacquacil folks!!). So I switched to SoftSwim. SoftSwim like the other two is based on Biguanide. It is very similar to what is used to clean contact lenses. It is extremely easy on your skin, won’t bleach your clothes and won’t hurt your eyes. It has the same components as you’d find in chlorine pools: sanitizer, algicide and a clarifier/shock. It may cost a little more, but you’ll appriciate it I promise- especially if you have an above ground pool and or PVC piping- chlorine will eat your liner and dry out our pipes over time- Biguanide doesn’t harm plastics!

Above Ground Pool Plumbing

I had an above ground pool many years ago. It was a really nice 18′ round setup. The pump/cleaning setup however wasn’t real ideal. In fact it was cumbersome and a lot of times when setting up to clean the pool got you wet in the process. The first thing you’ll notice is that I’m *not* a plumber…

I decided to hard plumb the pump and filter. The stock setup they give you is cheap flex hose that really isn’t all that flexible and tends to restrict the flow a bit.

The hard piping was done to with the following goals in mind:

  • attach the vacuum hose without using the skimmer
  • be able to direct the water output through the vacuum hose to clear out any air in it
  • be able to hook all this up without turning off the pump (if you can turn two valves together so as not to block the water flow completely…)

What I came up with was 5 valves and a really cool solution.

Heres what they do:

Under the skimmer is a valve that turns off the skimmer.

After the pump is a valve to cut off water to the sand-filter from the pump (inconjunction with the skimmer valve this also prevents water from draining from the filter if you remove the pumps filter basket).

These valves together allow you to clean the in-line/in-pump filter without the water draining from the skimmer side or the sand filter side– essentially blocking all water to/from the pump.

The two valves to the right of the skimmer allow you to switch the cleaning hose (the pipe that goes to the right from the middle of the two valves) to either get water from the pool or put water in the pool from the sand-filter.

The valve at the top right of the picture cuts off the water flow to the water return (from the filter normally)

With this setup all of the original design goals were met.  A year or so after this was done I added some unions (the grey things on the pipes) to allow the easy disconnection of the pump from the system for maintenance.

UPDATE! 7-8-09  Thanks to the many readers who have asked very good questions!  I have created the diagrams below to help clarify the plumbing/ water flow.  Let me know if I can be of any help!

The Pond v1

Everyone needs a little pond in their yard. It doesn’t have to be big to take up a lot of your time but it can really add something to your yard. We built ours in ~2001.It’s about 4×8 and as you can see below pretty nice. It’s not as professional as one might like, but for quick and dirty it suits our needs.

We added the small stones and border about 1 year after the main pond. It all started with a kit that had a liner and crappy pump. I’ve since added a 1200gph pump to run the waterfall.

We added lillys to the main water and reeds to the waterfall. As you can see below we had a bloom. What a great looking flower!

Shortly after the lilly bloom we had some late night visitors. I came out one morning to find the pond water filled with what looked like, well, lets call them frog eggs. Shortly after we had hundreds if not thousands of tadpoles in the pond. We fed them for a while and they eventually turned into little frogs that took over the back yard.

See if you can find all the frogs in this picture:

These are some closeups of some of the babies while they still had tails and one of a juvenile that looks like a small version of the adult.

We found out that spashing water around the rocks isn’t necessarily a good thing. This is the pond in the fall of 2003. See the rocks? Yuck!!

We were able to get most of the crud off the rocks with a pressure washer. Well worth the effort to return the rocks to normal.

CD Burning

Ever wondered what happens to a CD if you put it in the microwave? It’s actually pretty cool!

I put a CD in there and in about 4 seconds it was “done”. It actually looks kinda cool, almost like a fractal image or something.

There is a video in addition to still images. Apologies to Office Depot– their discs were the only ones I had on hand. Their discs are my favorite low cost CD medium!

The video shows a CD upright in the little blue holder and one flat. Watch the fireworks! Each disk was in there for about 4 seconds. I didn’t want to melt it or destroy the microwave. I would expect that a weaker microwave would take longer and a stronger one less time.

Jacob’s Ladder

Jacob’s Ladder : A Jacob’s Ladder is the type of high voltage “climbing arc” display seen in many old Sci-Fi movies. Jacob’s Ladders come in all shapes, styles, and sizes.

Back in college my roommate and I set out to make one. This is what it looked like:

This was made using a 11K volt neon sign transformer, a metal clothes hanger, black tape and a box. In its purest form shown above, its extremely dangerous. Cool, but dangerous. “Don’t Try This At Home Kids!”

We later added a large flask over the wires to see what the ozone looked like that was being generated by the spark- ozone is yellow and smelly!!

Recessed Shelving

I saw this idea in a wood working magazine. They were making use of the space under a stair case by making shelves and recessing them into the space under the stairs.I adapted the idea to put shelves into regular walls. The original reason for this was to cover a massively messed up wall patch job. We had a wall heater in the wall from the 60’s that had to go. Unfortunately to get it out required the drywall to be removed. This left a huge hole. The patch job that was done on it really sucked so I had to do something.

The first phase of the shelves is done, now I just need to get the actual shelves made.

Below are pictures of what I did:

Since the first hole was ‘pre cut’ I’ll show the second one that I did from scratch.

The first step is to get the drywall cut out. I matched the first hole from the heater. I kind of cheated by making the shelf only as wide as the space between studs. This has the benefit of being easier…

So after the drywall is gone I needed a 2×4 at the top and bottom in order to have something to attach the veneer to. I ended up with a cross brace in the middle so I cut the nails and used it as the bottom 2×4.

The next step is to prepare/cut/stain the veneer. I purchased 2 4×8 sheets of veneer that’s about 1/4 inch thick. I assembled the veneer from the back to the front. The back piece had to be held in by the sides and top because it’s against the drywall of another room. Nailing through it would ruin the wall on the other side.

I used brads for attaching the sides. The final pieces were the borders, they were attached with brads too.  The final step was filling gaps and putting quarter round trim in the back corners. Overall I think it came out rather well!
