I didn't stick my hand in the sump to check, but the head of the pump is screwed into the bulkhead. I don't know if it completely goes through the bulkhead into the sump. If it doesn't, a cap on the inside might work. But as my luck goes, I am sure the pump head probably screws through the bulkhead and into the sump...<a href=showthread.php?s=&postid=12847621#post12847621 target=_blank>Originally posted</a> by michika
Could you just shut the pump off, cap the bulkhead on the inside, and go from there?
If I am lucky, the Blueline 70 pump will only need an impeller which I happen to have a spare in stock.<a href=showthread.php?s=&postid=12847726#post12847726 target=_blank>Originally posted</a> by melev
While I don't envy the task ahead of you, it looks like you need to drain that compartment of the sump, unscrew the nut on the bulkhead and extract the bulkhead with pump and associated plumbing to look into it.
When you reinstall it, you could modify that connection to your sump to avoid that job ever again.
So you think the impeller of the feed pump is calcified in place?
I'm pretty sure that I am going to have to drain and removed the entire bulkhead to get at the pump. It looks next to impossible to be able to get the head of the pump off attached to the bulkhead.<a href=showthread.php?s=&postid=12847736#post12847736 target=_blank>Originally posted</a> by stdreb27
I think you are going to have to empty it. Because you aren't going to be able to remove the pump. Unless you take the head of the pump off while it is attached to the bulkhead. It doesn't look like you have room to spin the pump off.
LOL..it does..I'll let Marc answer your question....<a href=showthread.php?s=&postid=12847940#post12847940 target=_blank>Originally posted</a> by michika
That sucks on too many levels. Do you normally keep stock on quite a few replacement parts?

It's not going to be the impeller. Without water the Bluelines probably overheated and fused. You may not even be able to physically remove the impellers.
If you can't get the pump off without draining the sump I would suggest the following:
-- Get schedule 80 threaded bulkheads. These bulkheads will give you a secondary benefit of being able to plug them with a threaded cap from the inside, should other measures fail;
-- Drain and ditch the crappy bulkhead(s); replace with schedule 80. This may require a slightly larger hole. A larger hole can be made by using a curved file to get an exact fit, or you can make a plug the size of the current hole with scrap wood, and then go up in hole saw size to fit the new bulkhead(s). My preference would be to use a file. This is more work, but you get a much better fit.
-- Ditch the Bluelines and replace with a Sequence Hammerhead and a manifold which feeds the chiller, reactors etc. All of those devices can be run off one good pump. Because the Sequence is not a magnetic drive pump, it is much less likely to seize up in a no-water situation. They provide excellent reliability, less heat, and an extremely good flow curve.
-- When you add the pump, put a ball valve and union between it and the sump, as well as between it and the manifold.
IMO, there is simply no reason to have multiple pumps driving your equipment. Then you can have a spare pump that can be swapped in when you do any cleaning, or in the unlikely event of a pump failure.
My Hammerhead has been running my ENTIRE system for 26 months, 24/7 with ZERO problem. It endures power outages, spikes etc. with no problem, and costs slightly more than the Blueline 70.
More flow, less wattage, and IMO, much safer.
All good points, but at this time, I think that I am going to drain the sump to repair or replace the pump. There isn't enough room to install union ball valves between the pump and sump. See the picture below. They would be nice, but I just don't see any way to install them in the present setup.<a href=showthread.php?s=&postid=12848425#post12848425 target=_blank>Originally posted</a> by jnarowe
