Delta UV system problem

Hello everyone,

Hoping someone here will be knowledgeable and able to help me with my Delta UV system. I have the ES-80 model, to be specific. The quartz tube that sits in the unit is cracked and the whole unit is leaking. I bought a replacement quartz tube, UV light, and seals (O-ring, compression seal, rubber boot), but I can't get the old quartz tube out! For some reason, it is wedged in tight. I have tried putting my finger in and pulling out hard with no success. I've tried needle nose pliers and they just break off small chunks of glass from the tube, but it doesn't budge at all. It is really wedged in there good and I can't really see any way to get it out. I was hoping someone on this forum may have an idea for how to get this out so I can replace it and get the UV system up and running again.

Here is a link to the schematic of the unit:

It is item #2 that is broken and wedged inside. The cost to replace the entire thing is $700! So, I'm hoping to try to avoid that.

Would appreciate any advice. Thanks in advance.
 
Welcome to TFP.

Is your pool indoors? We do not use or endorse the use of UV systems for outdoor pools. UV systems may benefit indoor pools by burning off CCs. So experience here with UV systems is limited. Let’s see if anyone comes out of hiding.

Please create your signature with details of your pool and equipment.
 
I have installed several and repaired more on both pools and spas. They were fairly popular in the boulder area, where I lived for several years. Used in conjunction with H2O2 (hydrogen peroxide) they are one of my favorite maintenance systems. They are also quite common in sports therapy and hospitals. As well as stainless steel spas such as Diamond Spas. The only byproduct is oxygen and water. It is the only system I consider to be chemical free.
I am assuming you removed the compression nut labeled 5 in the drawing? I had one break on me, the glass fell out of the plumbing connection. Rinsed it out good and put it together.
 
How are the bulbs for these? I have used UV for aquariums for algae control and they work quite well but the bulbs lose their effectiveness in under a year. New bulbs are great but they just don't last and are expensive to replace.
 
The use of hydrogen peroxide as an oxidizer must be accompanied by an approved sanitizer. As such it is never recommended here unless in a system alongside biguanide for sanitation. Not that this is actually recommended here, but it is an approved option. Peroxide and UV is not.
 
At the time in Boulder uv peroxide was approved. I can't say now, as that was over a decade ago, but we did not use biguanicide and had no trouble getting a UL listing on our uv peroxide systems. I worked for a manufacturer of steel and copper spas. Traditional maintenance was not really an option. They also use it in hospital physical therapy tubs and professional sports facilities, specifically the St. Louis Blues hockey team and the Rams when they were still in St.L. I personally worked on both teams equipment. No biguanicide there either.
 
Underwriter Laboratory does not get a say in approved sanitation systems. That would be the EPA. And the EPA does not approve the use of a system that does not provide sanitation to the bulk water of a system. UV provides none outside of the reaction chamber, so it is not approved as a primary sanitizer. For a spa primary sanitizers would be Chlorine, Bromine, Biguanide, and Silver Ion/MPS.

Your confusion might be because actual regulation is restricted to public water bodies. This is true, a residential owner may use any or no system as they choose. However, TFP follows the guidelines and only assists in the management of sanitary water care systems.
