We love these little pumps! Very efficient requiring low wattage.

I had a Laing D5 710 B connected directly to a solar panel to circulate water through a solar water heating system. The pump worked flawlessly for 6 years then failed. I was talked into buying a Topsflo TD5 to replace it. The TD5 is obnoxiously loud, I could barely hear the Laing. I'm going to buy another Laing. I derated on star because I wish it lasted longer.

I use this pump to circulate pool water over a waterfall. It keeps water in motion all day and enables chlorination. It is very effective and easy to rig up. I may want to order a larger pump in the future.
Laing D5 solar pumps by Tom Ligon

Ive been using two Laing D5/090B pumps for several years, and they have run trouble-free circulating hot propylene glycol solution in a solar radiant heat floor application. However, the /090 does not move quite enough fluid (even with the check valve removed), so Im back for a /710. My one complaint is that Laing does not seem to distinguish the power consumption of these two pump capacities. One would think the 720 draws more than the 090, but they dont show a difference in the specs.

This pump works great, BUT Dont ever let get the smallest leak in the tubing where a small drip can travel down the side and then gets inside the motor very easily. It will short it out. It seems the seal on these pumps dont seal a thing. When you call the company about it, they deny you any results due to "its your fault for letting it get wet". I called the manufacture and they stated a little water shouldnt hurt it. It seems when you call AltE Store, you dont get anyone who can help you and when you finally do, they deny you any help in the end. I will never do business with this company agagin. First they try to rip me off and only ship 1 of 2 pumps, I had to fight with them to get the second one I paid for and now the pump leaked and fried out. Dont do business with a company like this when they dont care about the customer at all. When you call to complain, dont ever expect to get any help at all either.
