SOURCE: pentair 320 (inline) clorine not disolving

I am not sure if you have solved this issue, or not, but just in case.

If the tablets are not dissolving, there are two possible reasons. The first is that older tablets do not dissolve that well and if this is the issue, but new ones.

The second is that the 320 has a small screen at the bottom of the tubing. This can become clogged, or some the the tubing, and will need to be cleaned. The best thing to clean the parts on the 320, or other In-Line Feeders, is NON-ACETONE FINGER NAIL POLISH REMOVER. Make sure you use the NON-ACETONE kind since Acetone can melt the plastic parts!

You just need to soak them in the polish remover and rinse. If scrubbing is needed do so with a soft cloth, tooth brush or other non-abrasive material. For a parts breakdown and manual on the feeder, please follow the link below.

SOURCE: Flow issues through MasterTemp 400

I am only asking, because I noticed that you reported that this is a 400,000 BTU heater. And you are speaking of spa jets?
And... You stated that you are seeing pretty good flow coming into the pump, because you can see through the lid of your pump. This provides for me, a red flag. If water is coming into the pump at a good pace, it's got to be going somewhere, right?
you can't have X amount of water coming into the pump and have less then X returning to the spa. If this be the case, then you have an underground leak, and you will be noticing a water loss problem. So... i'm going to take a guess, that this may be a pool/spa combo?
if so, my guess would be that certain valves, are not properly opened or closed. And I would guess that water is returning to the pool, and the remainder of the water is flowing back through the spa jets, that you are reporting.
if this system that you are reporting about, is only a spa, then I will join the club, I too am stumped.

SOURCE: pentair 320 (inline) clorine not disolving

Three possible solutions, and I have personally made use of all of them with great success.

1. A common reason why the flow of water through the Pentair 320 canister is insufficient to dissolve the chlorine tablets is that the pool filter is dirty or just too old with ingrained sediment. If your pump pressure is continuously running high then this usually indicates a dirty or old filter that is making it difficult for the pump to get an adequate flow of water through the chlorinator. If thoroughly cleaning it makes no difference, treat yourself to a new filter; it's often an immediate fix and the pump pressure drop may amaze you. Old filters that have served their time are deceiving. They may look clean but the fine sediment trapped in their fibers can seriously degrade performance downstream in the chlorinator.

2. Another trick to help SEE what is going on is to replace the short black feeder hose to the Pentair 320 canister with PVC tube, 5/8" outside diameter, 1/2" inside diameter, and a short piece of Pyrex tubing inserted into the middle of the PVC tube to serve as a clear sight glass. PVC tube is rated 100 psi and is readily available at just 50 cents a foot at local hardware stores. Pyrex tube with an outside diameter of 1/2 inch (13 mm) can be bought cut to length for about a dollar per inch from EBay sellers. I also strongly recommend swapping this new feed tube assembly to the UPPER inlet of the chlorinator and moving the plug from there down to the lower inlet. See the attached photo.
You will need an 8 inch and 3 inch length of PVC tube, and a 4 inch length of Pyrex tube. Insert the ends of the Pyrex tube 1/2 inch into each piece of PVC tube with some Goop glue smeared all around the outside of the Pyrex ends. Do not get any Goop inside the Pyrex tube, and do this as quickly as possible, rotating the Pyrex as you insert it into the PVC to ensure that the Goop forms a complete seal. Then let it set, preferably for 24 hours.
Now you have a new feed tube 14 inches long in total, 3 inches of which is the Pyrex sight glass. Just take the unions and spring off the original black hose and transfer them to the new PVC tube, putting the spring on the 8 inch piece of PVC tube. The 3 inch piece of PVC tube should be at the top of the feed where it enters the Pentair control valve.
You will now be able to observe the rate of flow of bubbles in the Pyrex tube (transparent PVC tube soon becomes opaque because of the chlorine but Pyrex remains clear) and know if water is proceeding up the tube and then cascading down over the chlorine tablets. Adjust the Pentair control valve to check if the bubbles speed up and slow down.

3. Lastly, when you open the Pentair 320 to insert new chlorine tablets, the water will normally drain down and out of the canister. IMPORTANT - When you restart the pool pump, keep the cap OFF the canister but have it ready. Assuming you have the Pentair control valve set above 0 (zero) flow, you should soon see water starting to flow through your new PVC feeder tube and then entering and rising up in the canister. When it gets past the top of the chlorine tablets screw the cap on until it feels firm but not cranked hard. If it leaks a little, tighten until that stops. Now you have got rid of that potential air trap that can prevent water rising to completely cover the tablets. Do this EVERY TIME you add new tablets to the canister.80edc77f-aab6-45be-854b-dcd213e89f9c.jpg

1986 cadillac when i go to turn the car over the fuel injectors only drip fuel and donot spray... i took the fuel pressure reg apart and cleaned it all up and bought a rebuild kit... still doing the same...


most likely (in the order):
Fuel pump Fuel filter Dirty injectors
To check the fuel pump just put a fuel pressure gauge in the sytem and check the pressure when the pump primes, should be around 40-6- psi. This can be caused by both the pump and filter but most likely the pump unless the filter is VERY dirty and has never been changed (has it?)
if the pressure is good the injectors can be removed and taken some place where they clean and measure them.

Does salt water corrode the metal bands on the inside of thr filter.It is a CleanandClear (CCP-240) Part # 160310


No not at all. Just make sure saline (salt) levels are within recommended range for salt system. Your PH and ALK however are the real culprits. When PH is low metal disolves into water, when PH is high metals come out of solution and cause staining.

I have a Pentair 320 automatic chlorine feeder. I have filled it with chlorine tabs, but I am still getting a zero reading for chlorine when I test my pool water. Can it be plugged?


It can be but probably isn't. A three inch tab is meant only to maintain your chlorine level. You must first bring the chlorine level up to specs, by adding either liquid or powdered chlorine, than add one or two tabs a week to hold it at that level.

first: Low pressure is actually good. It means that every thing is clean and water is flowing freely. Three things can cause the filter to pass things thru. First is a rip or tear that you might have missed in a filter grid. Second is a cracked manifold.(The manifold is what the grids plug into) Third is the spider gasket may be worn or broken. (This is the gasket in the valve)

I installed a new pentair de filter and new multiport valve. at start up the filter pressure reads 40 psi. after multiple backwashes and rinses the pressure goes down to about 15 psi but slowly climbes...


If the pressure is 15 psi on recirculate, and high on filter, the problem is the filter itself, or the valve plumbing. The DE filters are unusal in the fact that they are plumbed like a sand filter, NOT the cartridge filter. If you could give details as to which filter AND multiport valve you have (look on sticker for model number on valve) it would help to figure out if the problem is in the filter or valve.

Pool heater won't kick on


check the gas line pressure; (if this was a homeowner installation you will not be able to check the gas pressure) dirty filters are the number one cause of heater malfunction. before you do anything else break the filter apart and clean completely and recharge with diatomaceous if applicable. also check the pump baskets and make sure there is no debris in the basket or blocking the impeller inside the pump. if this doesn't solve your problem call pentair tehcnical support
